Abstract:
This paper aims to investigate the animal welfare spawning poultry farms to analyze production costs and profit structure to foster sustainable spawning poultry farms. According to an analysis of 55 animal welfare certified spawning poultry farms, animal welfare certified spawning poultry farms have 1.6 to 1.9 times higher production costs and lower livestock productivity than general farms, but the income rate is 39.3%, which is three times higher than that of general farms. Animal welfare certification is economical by improving the income rate and increasing total income.

Abstract:
Poultry farming is one of the key branches of agriculture. Every year, the demand for dietary products of poultry farms increases, both consumers and producers are interested in the development of agricultural enterprises that supply poultry meat and eggs. In the market of the region there are a large number of poultry farms that supply meat products. The competitive environment of modern poultry farms is characterized by acute competition for the consumer. The solution to the problem of increasing the competitiveness of enterprises involves the development of measures to achieve and maintain competitive advantages in this market. The article presents the analysis results of the competitiveness for key suppliers of poultry meat and eggs in the regional market of the Krasnoyarsk region. The criteria of poultry farms competitiveness in the region are defined. Expert assessments of competitors based on the "4P"concept are compiled. Based on the results of the analysis, a competitiveness diagram of the largest regional producers of poultry meat and eggs is compiled. On the basis of the competitiveness polygon, the development directions of competitive advantages of poultry farms in the region are identified. The proposed measures to promote sales in the format of outside trade will lead to changes in the competitiveness polygon of poultry farms. The article presents recommendations for the acquisition and development of stable competitive positions in the regional market of poultry products. The key success factors influencing the competitiveness of poultry farms in the regional poultry meat market are identified, the most important trends in the development of the competitive environment and ways to improve the competitiveness of poultry farms and their adaptation to changing conditions are presented.

Abstract:
Biosecurity in poultry farms represents the first line of defense against the entry and spread of pathogens that may have animal health, food safety, and economic consequences. The aim of this study was to assess biosecurity compliance in poultry farms located in a densely populated poultry area in North East Italy. A total of 259 poultry farms (i.e., broilers, turkeys, and layers) were surveyed between 2018 and 2019 using standardized checklists, and differences in biosecurity compliance between the poultry sectors and years (only for turkey farms) were tested for significance. Among the three sectors, turkey farms showed the highest compliance. Farm hygiene, infrastructure condition, cleaning and disinfection tools, and procedures were the biosecurity measures most complied with. Some deficiencies were observed in the cleanliness of the farm hygiene lock in broiler farms, as well as the presence of the house hygiene lock in broiler and layer farms and an adequate coverage of built-up litter in turkey and broiler farms. In conclusion, this study highlighted a generally high level of biosecurity in the visited poultry farms (probably due to the stringent national regulation and the integration of the poultry industry) and identified some measures that still need to be improved.

<em>The study was conducted in Urban Community of Niamey at modern and semi-modern farms provided an overview use of agro-industrial by-products in animal feed. Among 57 farms only 17 farms, including 10 beef farms, 2 sheep farms and 5 poultry farms were systematically surveyed. All farm managers are men. 60 and 33% are respectively officials at the level of poultry farms and ruminant farms. Farmers make up 25%, all of which own beef farms. There is also a predominance of adults, 60% at poultry level and 58.33% at ruminant farms. We note the use of a variety of agro-industrial by-products in animal feeds, in this case by-products derived from vegetable processing (wheat bran, exfoliated cotton cake) and animal processing (fish and fish meal ...). There are also some concentrates for poultry feed. Agribusiness by-products are increasingly used in urban livestock production but their valorization needs to be improved.</em>

Abstract:
Poultry and poultry products are the common sources of Salmonella,which is one of the serious food-borne bacterial diseases in humans. Little is known about the status of Salmonella and their antimicrobial susceptibility in poultry farms in Addis Ababa. This study was conducted to estimate the prevalence and antimicrobial susceptibility of Salmonella isolates and to investigate possible risk factors for the occurrence of Salmonella in poultry farms in Addis Ababa. We recruited 58 poultry farms, from which 471 poultry-related samples and 44 stool samples from in-contact humans were collected. The isolates were tested for their susceptibility to 11 antimicrobials using the Kirby–Bauer disk diffusion assay. The farm-level prevalence of Salmonella was 36.2% and the sample-level prevalence was 6.4% for samples taken from poultry farms and 4.5% in human stool samples who have contact with poultry. On-farm waste disposal practices and chicken being purchased from different multiplication farms were significantly associated with Salmonella positivity of the farms (p<0.05). Eleven (34.4%) Salmonella isolates were resistant to streptomycin, and nine (28.1%) were resistant to tetracycline. Thirteen (40.6%) Salmonella isolates were resistant to two or more antimicrobials tested in this study, whereas resistance to 3 or more antimicrobials was detected in seven (21.9%) isolates. In conclusion, a high prevalence of Salmonella and a high rate of resistance to multiple antimicrobials were detected in poultry farms in Addis Ababa. Hence, implementation of strong biosecurity measures and rational use of antimicrobials are recommended.

Abstract:
The subject of this research article is the investigation of factors and the rate of mortality in broiler chickens in poultry farms in Maymana city. This article examines the technical, technological, and managerial factors related to poultry farms and aims to assess their impact on the mortality rate of broiler chickens in Maymana city farms. This research can contribute to improving the conditions of chick rearing and reducing mortality rates in the broiler poultry industry. The investigation of factors and the rate of mortality in broiler chickens in poultry farms in Maymana city holds great importance in the broiler poultry industry. The mortality of chicks in the early stages of the production chain leads to profitability and performance decline in poultry farms due to technical, technological, and managerial issues. A detailed examination of these factors and the determination of appropriate strategies to reduce chick mortality can enhance the performance and efficiency of the broiler poultry industry. Therefore, this subject is of significant importance and contributes to sustainable development and improvement in the quality of broiler chicken rearing. The objective of this research article is to investigate the technical, technological, and managerial factors and their impact on the mortality rate of broiler chickens in poultry farms in Maymana city. In this research, using a descriptive research method, the status of the poultry rearing industry and the relationship of its dependent variables were examined. After preliminary investigations, 17 active poultry farms were selected using the systematic sampling method (SD) for conducting face-to-face interviews and completing questionnaires. The results showed that many of the examined farms did not reach a satisfactory level in terms of technical, technological, and managerial factors. The influence of each of these factors on animal losses in broiler farms was 31.71%, 33.08%, and 34.19%, respectively. Additionally, disease factors also had an impact on animal losses. The common diseases in broiler farms in Maymana city included Newcastle disease, avian influenza, and Gumboro, which caused significant losses in the chickens.

Abstract:
Poultry farming is a common practice in Ghana. Antibiotics are used, particularly in commercial poultry farming, as growth promoters and to prevent and cure infections. However, there is little information on antimicrobial usage in domestic poultry farming in Ghana. This study aimed to describe antimicrobial usage in commercial and domestic poultry farming. A cross-sectional survey was conducted within the Ashanti region of Ghana including 33 commercial farms and 130 households with domestic poultry farming. The median poultry population on commercial farms was 1500 (IQR: 300–3000) compared with 18 (IQR: 10–25) on domestic farms. The majority (97%, n = 32) of commercial farms used antimicrobials, compared with 43% (n = 56) of the domestic farms. Commercial farmers were 6.1 (CI: 3.2–11.8) times more likely to read and follow instructions on antimicrobials in comparison with domestic poultry keepers. About 11% of domestic and 34% of commercial farmers had received education on antimicrobial usage. None of the commercial farmers used herbal remedies; however, 40% (n/N = 52/130) of domestic farmers administered herbs. The misuse of antimicrobials in domestic poultry production calls for stricter regulations and training to limit the emergence and spread of antimicrobial-resistant bacteria among poultry.

Abstract:
This study aimed to characterize farming practices and the use of antibiotics in the process of peri-urban poultry farming in Burkina Faso. Surveys were carried out on poultry farms with a questionnaire sent to 121 breeders in Ouagadougou and its surrounding areas. The results showed that poultry farming is dominated by males (79.3%) with a low level of education. Most poultry farmers make very little use of the services of an animal health specialist. Almost half (50.4%) of poultry farmers used a combination of modern treatment and decoction obtained from local plants. Self-medication was estimated at 73.6% while 38% of the drugs used came from unauthorized street sales. Poultry farmers (36%) said they didn't respect the recommended doses. Unhygienized poultry manure is discarded in nature or sold for use in fields or gardens. These practices present risks of spreading multi-resistant bacteria. This study provides an overview of husbandry practices and antibiotic use in peri-urban livestock in Burkina Faso. Good breeding practices and rational use of antibiotics in poultry farming will limit the misuse of antibiotics but also the proliferation of antibiotic resistance.

Abstract:
Campylobacteriosis, a human infection caused by thermophilic Campylobacter spp. (particularly C. jejuni and C. coli), is the most commonly reported zoonosis in the European Union and one of the main bacterial causes of human gastroenteritis worldwide. Domestic poultry are the main reservoir of these microorganisms and harbour them without clinical manifestations. Handling and consumption of contaminated poultry meat has been reported as main source of human infection. Although campylobacteriosis is generally a self-limiting illness, severe cases require antimicrobial treatment, with macrolides and fluoroquinolones used as first-line therapy, while tetracyclines are second-choice drugs. Nowadays resistance to these antimicrobials is increasingly observed in C. jejuni and C. coli, determining a worldwide concern for public health, since resistant strains can be easily transmitted from animals to humans via the food-chain. Despite the high number of commercial broiler and turkey farms in Northern Italy and the economic importance of this sector in the Italian animal production, few on-farm studies have been carried out to investigate on the colonization of poultry with thermophilic Campylobacter spp. in this area. Considering that, together with the remarkable public health implications of the presence of Campylobacter spp. in poultry farms, the present study was aimed at determining the occurrence, the genetic diversity and the antimicrobial resistance of thermophilic campylobacters in the two leading poultry species reared for meat production in Italy, i.e. broilers and meat turkeys. A total of 10 broiler flocks reared in 7 different farms in Veneto and Lombardy regions and 3 turkey flocks belonging to 3 farms located in Veneto region were examined for the presence of thermophilic Campylobacter spp. by collecting cloacal swabs from randomly selected birds. Broiler flocks were sampled once, while turkeys were monitored with several samplings for the whole production cycle in order to evaluate the development of the colonization over time, because it has not been deeply studied in turkeys. Campylobacter isolates were genetically characterized by flaA-SVR typing and then examined for their phenotypic antimicrobial resistance to a wide range of antimicrobial drugs by the disk diffusion method. The occurrence of class 1 and class 2 integrons was also investigated. A wide colonization by C. jejuni and C. coli was observed both in broiler flocks (7 positive out of 10) and in turkey flocks (all positive), with differences among flocks in the Campylobacter species distribution, although an overall dominance of C. jejuni was detected. Interestingly, the onset of colonization differed considerably among turkey flocks, but in all of them it persisted up to the time of slaughter. A high genetic diversity among isolates was detected both in broilers and turkeys, with most genotypes showing a flock- or farm-specificity. Most strains isolated from both avian species were resistant to a high number of antimicrobials, including those of first and second choice for human campylobacteriosis therapy. Conversely, either class 1 or class 2 integrons were not detected. However, it should be noted that differences between broilers and turkeys were detected both in genotypes colonizing them and in antimicrobial resistance, suggesting discrepancies among the two poultry species in the epidemiological dynamics of Campylobacter spp. Overall, this study provides new insights into the epidemiology of thermophilic Campylobacter spp. in commercial broilers and meat turkeys in Northern Italy and suggests that they may represent a concrete risk for the transmission of multidrug-resistant strains to humans in our country
La campilobatteriosi, un’infezione umana provocata dalle specie termofile di Campylobacter (soprattutto da C. jejuni a C. coli), è la zoonosi più frequentemente riportata nell’Unione Europea e una delle principali cause di gastroenterite batterica nell’uomo a livello mondiale. Le specie avicole domestiche sono il principale reservoir di questi microrganismi, dei quali sono carrier asintomatici, e infatti la manipolazione e il consumo di carne avicola contaminata rappresentano le principali fonti d’infezione per l’uomo. Nonostante la campilobatteriosi sia una malattia autolimitante, nei casi gravi è necessario un trattamento antimicrobico. Macrolidi e fluorochinoloni costituiscono la terapia d’elezione, seguiti dalle tetracicline come molecole di seconda scelta. Attualmente il fenomeno dell’antimicrobico-resistenza è sempre più comune in C. jejuni e in C. coli, e in tutto il mondo rappresenta motivo di grande preoccupazione per la sanità pubblica, poiché ceppi antimicrobico-resistenti possono essere trasferiti dagli animali all’uomo attraverso gli alimenti. Nonostante l’elevata concentrazione di allevamenti intensivi di polli e tacchini da carne nel Nord Italia e l’importanza economica di questo settore nel comparto delle produzioni animali italiane, sono poche le indagini svolte negli allevamenti di quest’area geografica per valutare la presenza di Campylobacter termofili a livello di produzione primaria. Alla luce di questo e delle importanti implicazioni di sanità pubblica della presenza di questi microrganismi zoonotici negli allevamenti avicoli, questo studio è stato intrapreso allo scopo di valutare la presenza, la diversità genetica e l’antimicrobico-resistenza di Campylobacter termofili nelle due specie avicole da carne maggiormente allevate in Italia: polli broiler e tacchini. In totale sono stati esaminati 10 gruppi di broiler di 7 diversi allevamenti di Veneto e Lombardia, e 3 gruppi di tacchini di 3 allevamenti veneti. In ciascun gruppo di animali sono stati eseguiti tamponi cloacali a soggetti scelti causalmente. In ciascun gruppo di broiler è stato eseguito un campionamento, mentre nei tacchini sono stati svolti numerosi campionamenti per valutare l’andamento della colonizzazione durante tutto il ciclo produttivo, aspetto poco studiato in questa specie avicola. I Campylobacter isolati sono stati caratterizzati geneticamente mediante flaA-SVR typing e quindi sottoposti ad antibiogramma secondo il metodo della diffusione in agar per valutarne la sensibilità a più antimicrobici. Inoltre è stata valutata la presenza di integroni di classe 1 e 2. È stata rilevata una notevole diffusione di C. jejuni e C. coli sia nei broiler (7 gruppi positivi su 10), sia nei tacchini (positività di tutti e 3 i gruppi), con differenze tra i gruppi nella distribuzione delle due specie termofile e una complessiva predominanza di C. jejuni. Nei gruppi di tacchini la positivizzazione è avvenuta in tempi molto diversi, ma in tutti è persistita fino al termine del ciclo produttivo. É stata riscontrata una notevole diversità genetica nei ceppi isolati sia dai broiler, sia dai tacchini e la maggior parte dei genotipi era esclusiva di un gruppo di animali o di un allevamento. Inoltre, la maggioranza dei ceppi isolati da entrambe le specie avicole era resistente a molti antimicrobici, compresi quelli di prima e seconda scelta nella terapia della campilobatteriosi. Al contrario, non sono stati riscontrati integroni né di classe 1 né di classe 2. É importante notare che sono state riscontrate differenze tra broiler e tacchini sia relativamente ai genotipi dai quali erano colonizzati, sia nell’antimicrobico-resistenza, riscontri che suggeriscono il sussistere di differenze tra le popolazioni di Campylobacter che colonizzano l’una e l’altra specie avicola. Nel complesso, questo studio apporta nuovi elementi sull’epidemiologia di Campylobacter spp. in polli e tacchini da carne del Nord Italia, che possono rappresentare un rischio concreto per la trasmissione di ceppi multi-resistenti all’uomo

Abstract:
Biodegradable wastes cause high emissions of greenhouse gases (GHG) if not properly treated. The emissions can be reduced by the development of an effective waste management strategy. Waste-to-energy technologies, such as anaerobic digestion (AD) can be utilised for this purpose. Biomass energy from wastes is of particular interest to Cyprus that has to meet legal commitments for reducing its GHG emissions by 5% compared to 2005 levels and increase the contribution of renewable energy sources to 13% by 2020. This research project is making a significant contribution to this effort. The research considered the quantities and distribution of biodegradable waste in Cyprus and developed the necessary methodologies and tools for their estimation and determination of the potential for energy production through AD. The study identified that the predominant biodegradable wastes in Cyprus are the biodegradable fraction of municipal solid waste (MSW), sewage sludge, solid and liquid agricultural residues and solid and liquid wastes from the food and drinks industries. According to the estimated amount of solid and liquid biomass from these waste streams, at least 4,200 TJ of energy can be produced through AD, which represents 4% of the national energy demand. Livestock production is a very important source of waste due to the high potential of biogas production with the aid of AD. The produced energy can satisfy the needs of a farm, reduce the consumption of fuel and provide renewable energy to the national grid. Simple methodologies were developed and implemented for the estimation of energy consumption of the farm and the respective GHG emissions. It was found that in Cyprus the annual energy consumption per animal is lower than most other countries, due to favourable weather conditions which reduce the energy needs for heating. The emissions from energy use in livestock production contribute 16% to the total agricultural energy emissions. Literature review on AD, confirmed the complexity of the process, due to the many microorganisms involved. To estimate the potential of biogas production from animal waste through AD, three methods were developed based on the accepted relations that exist between Chemical Oxygen Demand (COD), volatile solids (VS), waste digested and biogas production. The results show that livestock production could cover the complete agricultural energy demand and make a considerable contribution to the renewable energy targets of Cyprus. Due to the identified importance that AD could have for Cyprus and to overcome deficiencies of existing models, the software FARMS was developed. The tool can be used by any farmer, consultant or policy maker for the estimation of the potential of biogas production, associated costs, reduction in GHG emissions and comparison of scenarios for waste management. Furthermore, the validation of the tool is presented. This was done through comparison against data collected from existing AD plants and through testing by potential users.

Abstract:
This study analyzes the change in whole-farm net revenues and nutrient reduction from the implementation of five best management practices (BMPs) on a typical beef and beef-poultry farm in Shenandoah County. Whole-farm net revenues, resource allocation, nutrient loss reductions, and the cost efficiency of reducing nutrient losses were analyzed to assess which BMPs are the most cost efficient to implement, assuming the baseline scenarios have no voluntarily applied BMPs. The effects of stacking additional BMPs, in combinations of two or more, were also assessed. No-till cropping, winter wheat cover crop, herbaceous riparian buffer, fencing, and P-based NMP were the BMPs that were analyzed. Incentive payments from state and federal governments were incorporated into the cost of BMP adoption. A brief analysis of a farmerâ s time value of money, with respect to incentive payments, was also conducted. Results indicated that no-till crop management was the most cost efficient BMP, and was the only BMP to increase net revenues for both farm models. Fencing and P-based NMP were the least cost efficient for the beef farm. For the beef-poultry farm, fencing was the least cost efficient. The implications of this study are that farmers that choose to adopt BMP should evaluate both their interests in maintaining (or increasing) farm net revenues along with their interest in improving water quality through the reduction of nutrient losses. There is potential for implementing multiple BMPs, while increasing net revenues from a farmâ s baseline scenario. For farmers and policy makers, no-till cropping can be a profitable and therefore cost efficient BMP to implement. Incentive payments are intended to encourage the adoption of BMPs by subsidizing a portion of the start-up costs. Policy makers should attempt to make cost-share payments reflect nutrient reduction goals. This can be done by analyzing both the compliance cost to farmers and the nutrient reduction effectiveness of BMPs.

Resumo: Os sistemas de produção animal em confinamento são ambientes artificiais que favorecem o aparecimento da comunidade de artrópodes, devido à oferta de recursos que beneficiam o desenvolvimento desses organismos em acúmulo de esterco. Muitos ácaros encontram condições adequadas de sobrevivência nesses ambientes. Neste trabalho estudamos a dinâmica da associação forética entre ácaros e coleópteros predadores, analisando a ocorrência, abundância das famílias de ácaros associadas a histerídeos, bem como a diversidade acarofauna, a ocorrência de forésia entre os mesmos, através do estudo das infrapopulações e infracomunidades e dos índices de prevalência, dominância e uniformidade em granja de aves poedeiras em São João da Boa Vista - SP. Foram usadas duas metodologias de coletas para este estudo: amostras coletadas manualmente do esterco e armadilhas de solo. Foram realizadas oito coletas nas estações do ano 2002 e 9 coletas no ano de 2001. Foram encontradas 4 espécies de ácaros associadas aos histerídeos. A família Ascidae foi registrada como sendo nova associação com histerídeos no esterco de granjas. A prevalência de ácaros foréticos predominou em Hololepta quadridentata
Abstract: Animal production systems under confinement are artificial agroecosystems which favor the development of an exuberant arthropod fauna, due to their high manure offer. These environments may provide adequate survival conditions for a number of mites. The purpose of this work was to study the phoretic association dynamics between mites and predaceous coleopterans, also focusing on the occurrence and abundance of histerids-associated mite families, as well as their infrapopulations and infracommunities, related indexes of constancy, dominance and prevalence. The sampling methodology included hand-collected manure samples and pitfalltraps. Eight gathering activities occurred in different seasons in 2002, and 9 gathering activities during the period of 2001. Associated to histerids 4 mites species were found. A new association has been found between histerids and the Ascidae family in poultry farms manure. Phoretic mites prevalence was prevailing in Hololepta quadridentata

Abstract:
The paper explores which farm types by specialisation direction2 (ten different types) and at what farm sizes by physical size3 (five categories) of specialised farms backed more production growth and productivity development in Central and Eastern European Countries (CEECs, EU104) over the period of 2005-2016. We compare EU10 average figures to EU27/15 averages and outline the changes by specialisation in total resource use of (i) labour (AWU), (ii) land (UAA) as well as in (iii) average farm size (UAA/specialised farms), (iv) total farm productivity (SO/farm), (v) labour productivity (SO/AWU) and (vi) area productivity (SO/UAA). We conclude that production and productivity growth of specialised farms in EU 10 differs by country, and by type and size of farming and, each CEEC has followed her own path of farm structure development in line with the country’s tradition and economic possibilities. We give regional characteristics of development in main specialisation types broken down to 5 farm size categories. We concluded the number of cereal farms increased in 6 out of 10 countries in all farm size categories and that of cattle farms went up in 5 out of EU 10 from 2005 to 2016. Farms with these two specializations have significantly extended agriculture land use and more than tripled production, but used more labor compared to basis year. SO/Farm/UAA/AWU productivity indicators of cereal farms increased quite a bit in most farm size categories in all EU 10 countries to a less extent in cattle, poultry pig and dairy farms. Growth in area productivity was led by pig, poultry, and cereal farms at E 10 level. Growth of the three productivity indicators in EU 10 are scattered quite a bit by farm types, and by countries but generally was headed by three farm size categories as 5-19.9 ha, 20-49.9 ha and 50-99.9 ha. However, the distance between EU10 and EU15 related to the level of production, land, and labour productivity still shows wide gap which needs to further narrow in the coming years.

Full text
Abstract:
Reticuloendotheliosis virus (REV) is an avian retrovirus that can cause immunosuppression, growth retardation and tumors. An attempt to define the extent of the economic damage to the poultry industry that it causes is discussed in this report. In addition to losses experienced by commercial laying flocks, reduced rates of hatchability and embryo developmental disorders were demonstrable due to vertical transmission of the virus. I. Eradication of REV In this project a comprehensive national program was applied for the eradication of REV from Israeli breeding stocks by the elimination of antibody-positive birds from the breeding program. The prevention of REV-infected breeders entering Israel was also implemented by serological examination of imported day-old chickens and turkeys for maternal antibody. At the same time commercial breeding flocks in Israel were surveyed routinely to measure the extent of environmental exposure to REV throughout Israel. II. Economic factors associated with vertical transmission on breeders and progeny It was observed that on some poultry farms exposure of breeding flocks to viral infection, if it occurs when the birds are immunocompetent, leads only to a seroconvertion event. In these flocks no differences were demonstrated between the performances of seronegative and seropositive birds. When the F1 generation was selected according to seronegativity of the parents, all the progeny were seronegative, indicating that tolerantly infected birds did not form a significant proportion of the parent flock. In sharp contrast, breeding flocks that became exposed to the virus about the point of lay or during the laying period, shed virus vertically for a brief period of time through the egg. Our epizootiological observations lead us to conclude that the progeny (laying pullets) becomes tolerantly infected and are immunosuppressed as they increase in age. Increased mortality and susceptibility to intercurrent diseases were recorded.

Full text
Abstract:
Avian influenza (AI) viruses cause infections primarily in bird species, although they are capable of spill-over infections into mammalian species, including humans. Many different strains of AI viruses are found in birds, but they can be divided into two groups based on their virulence in poultry: high pathogenicity (HPAI) and low pathogenicity (LPAI); both are capable of quickly spreading through a flock. HPAI infections often lead to severe clinical signs and high mortality while LPAI infections may not present with any clinical signs. Certain strains of AI have been associated with human case fatality rates of over 50%. Since October 2021, there has been a substantial increase in the number of AI infections reported both at commercial premises and in wild birds in the UK. The last FSA assessment on the risk to consumers of exposure to AI from the food chain was in 2015. Since the increase in infections may lead to an increased likelihood that poultry products from infected birds are entering the retail market, an updated risk assessment was commissioned to ensure advice relating to the consumption of poultry products is still appropriate. This risk assessment did not focus on the currently circulating outbreak strain but considered any AI virus. This assessment considered the risk of consumers acquiring an AI infection from poultry products, including commercial poultry, game birds, and table eggs. The risk of home processing of birds was also considered. The farm to fork risk pathway spanned from the probability that products from infected poultry would reach market to the ability of AI to cause infections in humans via the gastrointestinal route.

Gherman, Iulia, Victoria Cohen, Daniel Lloyd, Wioleta Trzaska, Niall Grieve, Johanna Jackson, Elaine Pegg, and Anthony Wilson. Risk of campylobacteriosis from low-throughput poultry slaughterhouses. Food Standards Agency, July 2023. http://dx.doi.org/10.46756/sci.fsa.xkw971.

Full text
Abstract:
Campylobacter is the most common cause of bacterial foodborne illness in the UK. Every year there are an estimated 300,000 foodborne cases in the UK, of which more than half are related to poultry meat. Campylobacter naturally lives in the guts of poultry. Undercooked chicken meat is the main source of exposure to Campylobacter. Thorough cooking kills Campylobacter. Cross-contamination of other food or work surfaces during preparation or storage of chicken can also cause illness. Campylobacter levels are routinely monitored in chicken carcases that are processed in high-throughput slaughterhouses, but this testing is not currently carried out in some low-throughput slaughterhouses. Each high-throughput slaughterhouse processes more than 7.5 million birds per year and each low-throughput slaughterhouse processes less than 7.5 million birds per year. Of the 1 billion birds that are slaughtered annually in the UK, around 5% come from low-throughout slaughterhouses. This report estimates the difference in risk of campylobacteriosis for products from low-throughput and high-throughput poultry slaughterhouses in the UK. This was necessary work to assist the FSA in establishing an appropriate level of sampling for low-throughput slaughterhouses. We considered the whole pathway of the chicken from farm to fork using the scientific literature, data from our own survey of Campylobacter in slaughterhouses (FS9990010), and business data and information on UK levels of infection. Campylobacter levels over a 3-month period (September to December 2021) from chicken processed by low and high-throughput slaughterhouses were the main data used for our comparison. We could find no data on differences in the supply of birds to low- versus high-throughput abattoirs, and no data on differences in the use of the meat after leaving the slaughterhouses. Based on analysis of the limited survey data available, we could not detect a significant difference between the proportion of highly contaminated samples from low- and high-throughput slaughterhouses. We also could not detect a significant difference in Campylobacter levels in slaughterhouses that perform religious slaughter versus those that do not. Based on the number of chickens per year that are processed by low and high-throughput slaughterhouses, we estimated the number of Campylobacter cases in the UK annually that are likely linked to low- and high-throughput slaughterhouses respectively. Based on the evidence available, we conclude that the frequency of occurrence of campylobacteriosis in the total UK population from chicken produced in low-throughput slaughterhouses is medium and for high-throughput slaughterhouses is high, with a medium uncertainty, as a direct consequence of the relative volume of chicken produced by each type of plant. The severity of campylobacteriosis is low, with low uncertainty. This assumes that the proportion of the total domestic consumption of chicken meat originating from low-throughput slaughterhouses does not change. The current sampling regime requires samples to be taken once a week. If more than 15 out of 50 of samples have high levels of Campylobacter, this is considered a failure and mitigations need to be put in place. We predicted that if samples are taken once every two weeks or once every four weeks instead, that would still allow us to identify some slaughterhouses failing to comply with the 15/50 exceedance rate. However, identifying issues will take longer and may not detect some failing slaughterhouses. Sampling requirements are not consistently applied in low-throughput slaughterhouses, and we did not have access to data on the steps taken when slaughterhouses recorded high levels of Campylobacter. Therefore, it was not possible to state the effect of changes in sampling requirements on per-portion risk. However, due to the small proportion of total poultry meat consumed in the UK that is produced at low-throughput slaughterhouses, changes to the official sampling requirements at low-throughput slaughterhouses are unlikely to result in a large difference in the frequency of occurrence of campylobacteriosis in the UK population.

Abstract:
This article is devoted to the presentation of the semantic interoperability of research and scientific results through an ontological taxonomy. To achieve this, the principles of systematization and structuration of the scientific/research results in scientometrics databases have been analysed. We use the existing cognitive IT platform Polyhedron and extend it with an ontology-based information model as main contribution. As a proof-of-concept we have modelled two ontological graphs, “Development of a rational way for utilization of methane tank waste at LLC Vasylkivska poultry farm” and “Development a method for utilization of methane tank effluent”. Also, for a demonstration of the perspective of ontological systems for a systematization of research and scientific results, the “Hypothesis test system” ontological graph has created.

Abstract:
A feasibility study was conducted, aiming to explore the potential effectiveness of UV/TiO2/O3 photooxidation technologies for simultaneous treatment of odorant and pathogen emissions from livestock and poultry operations. Several key parameters were tested in laboratory (US) and semi-pilot (Israel) scale conditions including: the effects of light energy dose (treatment time and light intensity), relative humidity and air temperature, UV wavelength, presence of photocatalyst (TiO2) and the presence of ozone. Removal and conversion of odor, target gases (sulfur-containing volatile organic compounds S-VOCs, volatile fatty acids (VFAs), phenolics, and ammonia), and airborne pathogens was tested. Up to 100% removal (below method detection level) of S-VOCs, VFAs, and phenolics, the overall odor, and up to 64.5% of ammonia was achieved with optimized treatment. Treatments involving deep UV band (185 nm) and photocatalyst (TiO2) were more efficient in removal/conversion of odorous gases and odor. The estimate of the operational cost of treatment was based on measured emissions of several odorous VOCs from full scale, commercial swine farm ranges from $0.15 to $0.59 per finisher pig. This figure represents significantly lower cost compared with the cost of biofiltration or air scrubbing.
