Full textAbstract:
The present study was undertaken to investigate the potential for heavy metals (Fe, Cr, Cd, Pb, and Cu) contamination of goat meat roasted with scrap tyres in Wukari using atomic absorption spectrophotometer (AAS). Goat meat samples were obtained from two slaughter points (new market and Mammara). The results revealed the mean concentrations of Fe, Cr, and Cu in the unroasted goat meat samples (UMN and UMM) in both new market and Mammara slaughtering points as 1.7600 ± 1.4000, 0.0012 ±0.0000, 0.8700, 3.2500 ± 0.0000, 0.0025 ± 0.0000, and 0.7850 ± 0.0071 mg/kg respectively. Cd and Pb were not detected in any of the samples. The mean concentrations of Fe, Cr, Cd, and Cu in the goat meat roasted with scrap tyres (RMN1 and RMM1) in both slaughtering houses (new market and Mammara) were 4.1300 ± 0.0141, 0.0025 ± 0.0001, 0.0011 ± 0s.0000, 1.1250 ± 0.0071, 5.1500 ± 0.0000, 0.0035 ± 0.0001, 0.0012 ± 0.0000, and 1.0500 ± 0.0000 mg/kg respectively. Pb was not detected in all the samples. Also, the mean concentrations of Fe, Cr, and Cu in the goat meat roasted with firewood (RMN2 and RMM2) in slaughtering houses (new market and Mammara) were 3.7750 ± 0.0000 mg/kg, 0.0013 ± 0.0000, 0.9850 ± 0.0000, 4.9150 ± 0.0071, 0.0026 ± 0.0000, and 0.8650 ± 0.021 mg/kg respectively. Cd was detected in the samples obtained from Mammara (0.0012 ± 0.0000) but was not detected in the samples collected from new market. Pb was not detected in any of the samples obtained from both slaughtering houses. The mean concentrations of Fe and Cu in (UMN, UMM), (RMN1, RMM1), and (RMN2, RMM2) in both slaughtering points were above the maximum permissible level set by (FAO) and (WHO).The result of this present study show that the practice of roasting goat meat with scrap tyres is dangerous because the meat could accumulate high and unacceptable levels of heavy metals that could pose a threat to human lives, and hence, should be outlawed.

Full textAbstract:
The study was conducted to ascertain the injuries of cattle and buffaloes at selected livestock markets of Bangladesh during transportation and slaughter. A total of 290 (212 cattle and 78 water buffalo) at Sagorica cattle market and 57 (24 cattle and 33 buffalo) at Fringibazar and Pahartali slaughter houses of Chittagong were examined during the period from January to April 2013. The frequency of different injuries during handling, transportation and slaughtering were assessed. The data of different type of injuries (e.g. abrasion, laceration, bleeding, swelling, scarification and wound) were collected from the market and slaughter houses by using visual observation and palpation method. The frequency of abrasion, laceration, bleeding, swelling and scarification of cattle were 73, 45, 4, 3, 67 and 87%, and of buffaloes were 71, 9, 23 nd 41%, respectively. All the injuries were higher in Haryana than Rajasthani, Shahiwal and Exotic non descriptive cattle breeds. The tail injury in cattle and buffaloes was 65 and 23%, respectively. In the slaughter house, the frequency of abrasion, laceration, penetration and scarification were 79, 75, 8, 75 in cattle, and 85, 70, 0 and 67% in buffaloes, respectively. From these findings it could be concluded that proper handling and care should be taken to avoid different injuries of cattle and buffaloes during transportation and slaughter.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19389 Bang.

Full textAbstract:
Two hundred and fifty slaughtered pigs for meat purpose, in various localities ofKathmandu Metropolitan City and Dharan Municipality were examined for Taenia cystsduring January 1997 to April 1998. A surveillance study was also carried out with butchers, meat sellers, farmers and porkconsumers to study the awareness of taeniasis cysticercosis.Data was collected from the hospitals to determine the status of taeniasis/cysticercosisinfection in humans. Out of 250 slaughtered pigs examined, thirty-four (13.6%) were found positive for cysticercosis. The sex wise prevalence rate of infection was 8.77% in male pigs and 24.05% in female pigs. The result reveals that females are infected more than the males. Out of 196 slaughtered pigs examined in Kathmandu, 28 (14.28%) were found positive, whereas in Dharan, out of 54, 6 (11.11%) were found positive. The result further reveals that the number of infected pigs is higher in Kathmandu than Dharan. It is due to the importation of infected pigs to Kathmandu both from rural areas of Nepal and India. The results show that pork consumption is risky from a public health point of view. In environments where animal cysticercosis is prevalent, human taeniasis/cysticercosis is likely to be present.Prevalence of Taenia solium infection in pigs was therefore observed and recorded for the first time in Dharan Municipality and Kathmandu Metropolitan Municipality in Nepal.Human cysticercosis cases were also studied. Out of 23,402 human biopsy casesrecorded from Patan Hospital alone during July 1993 - Feb 1998, sixty-two patientswere confirmed to have cysticercosis infection. Out of 62 taeniasis/cysticercosispatients, 40 cases were from Kathmandu and 22 were from outside Kathmandu. Amongthe 62 infected patients, 38 were females while 24 were males. The result reveals that the infection rate is higher in Kathmandu than outside Kathmandu. Sexwise data againreveal that females are infected more frequently than males.The surveillance study findings reveal that taeniasis and cysticercosis are prevalentin Kathmandu and Dharan due to various factors, viz,uncontrolled slaughtering, lack of a meat inspection program, lack of awareness aboutmeat borne diseases, unhygienic conditions of slaughtering places due to lack of slaughter houses, environmental pollution etc.The incidence of human taeniasis/cysticercosis could be controlled by raising pigsunder hygienic condition and improving the environmental quality in the pig slaughtering abattoirs under the supervision of medical and veterinary technicians. An effective veterinary public health activities should immediately be established in all 56 municipalities of the country for meat inspection and construction of slaughter houses.

Full textAbstract:
A survey was conducted to appraise the location, infrastructures, and slaughter operational activities in three abattoirs at Rumuokoro, Trans-Amadi and Rumuosi in Obio-Akpor Local Government Area of Rivers State, Nigeria. Thirty butchers of 10 per abattoir were purposively sampled for the study. The instrument used for data collection was a structured questionnaire. Data were analyzed using frequencies, percentages and mean statistics Results of the socio-demographic characteristics of the butchers revealed that they were all males, married, within the age of 35 - 44years, literate, with a butchering experience of 16 years upwards in private or public/Government owned abattoirs. The slaughter houses were located in areas devoid of bad odours, smoke, dust and close to coastal areas affected by tides to promote good sanitation. There were no adequately constructed lairages, Ante-mortem inspection and isolation pens were inadequate. There were no facilities and rooms for handling hides and skins, treatment of inedible and condemned carcass and meat. Animals were poorly restrained and not stunned before slaughtering. The slaughter houses had planned and controlled cleaning programs but lacked efficient disinfection operations and this will contribute to bacterial contamination of carcasses. The operational lapses by butchers were due to the use of obsolete facilities that lacked maintenance and inadequate supervision. This condition had brought about poor hygienic practices that undermine the quality of carcasses. The recommendations proffered are: the provision and maintenance facilities for effective operations to ensure carcass quality, to adequately enforce enacted laws on abattoir operations, there should be enlightenment for butchers and meat sellers, and there should be effective management of the wastes from slaughterhouses through regular fumigations and disposal systems.

Full textAbstract:
OF 3,900 non-gravid zebu ovaries examined at 3 Zaria slaughter houses, 2,652 (68%) were active, Ovarian activity was highest during the rainy season and anestrus highest during the dry season (P < 0.01). Anestrus non-gravid cows and empty cows with active ovaries had the lowest (135+41 kg) and the highest (170 +43 kg) carcass weight respectively. Aged anestrus empty COWS had the lowest carcass weight (127+28 kg) and mature empty cows with active ovaries had the highest (180 +47 kg). The incidence of anestrus increased with age. The magnitude of slaughtering of young and mature empty cows with active ovaries was discussed and it was recommended that rectal examination be done before culling animals in order to reduce this major source of loss of reproductively active cows.

Full textAbstract:
In 1984, we monitored 4 ranches with a total of 24 houses (15,000–20,000 birds/house) for 3 consecutive generations (January–August). On epidemiologic grounds, infection of birds did not originate at the hatcheries or the central water and feed. Considering all lots of birds, the infection rate increased from 2.3% by the 10th day to 9.5, 29.7, 47.9, 65.7, 78.6 and 81.8% by the 20th, 30th, 40th, 45th, 50th day and at slaughter times, respectively. Transmission from one generation of chickens to the next via the old litter is suspected, but not proven microbiologically. A 5-log reduction of Campylobacter jejuni was shown in experimentally inoculated litters stored at 17 and 30°C for 6 d and 8°C for 11 d. The houses remained empty for 9–29 d before being filled with new chicks. Carrier flocks contaminated the slaughterhouse equipment to such an extent that negative flocks processed afterwards resulted in contaminated meat. Lack of effective sanitation at the end of the day contributed to the contamination of meat from Campylobacter-free birds processed the next day. Feather picker drip water was positive 94% of the sampling times at levels of log10 3.4 (1.0–4.7). Scalding temperatures did not affect the level of contamination in the finished products (P>0.2). An ELISA based on heat-stable antigens was adapted for the detection of circulating antibodies. Of 56 broilers aged 50 to 68 d, only 2 (3.5%) 68 d old with log10 5.4 C. jejuni/g of feces were considered as positive. Birds considered negative harbored C jejuni in their ceca at levels of log10 2.0 to 5.4/g of feces. Five out of 6 (83%) 18 month-old hens were considered as positive. Yet, none of these birds were found carrying C. jejuni in their feathers or ceca.

Full textAbstract:
Based on the last national livestock census in 2013, the population number of cattle and buffalo have reduced by 15% compared to that in 2011. The highest reduction happened in Java that reached around 24-27%, while that in Bali and Nusa Tenggara was 25%. One of the reasons was caused by decreasing number of cows due to the increase of productive cows slaughtered every year. Number of cows slaughtered in Bali, Nusa Tenggara, and South Sulawesi had reached on average of 72% from total slaughtered, where more than 90% were productive cows. Reasons for slaughtering productive cows were due to: (1) Lower cows price; (2) Limited bulls supply; (3) Local government regulation on inter-island trade; (4) Weak and inconsistent law enforcement; and (5) Lack of understanding on criteria for productive cows by farmers. Increased rate of slaughtered cattle and increasing rate of inter-island trade volumes that higher than the rate of cattle population had caused the decrease of national cattle population. There are currently needs to improve and develop operation slaughter-houses under management of local state enterprise. The management applies on certain mechanisms that sort of incoming productive females according to different grades into allowable to be slaughtered and selected for breeding females, which could be further traded inter-island as supplier of cows for other regions. This strategy may help the central government to meet the demand for productive cows, particularly in Sumatera and Kalimantan which have abundance of feed biomass resources. Policy support is needed as instruments for all interested stakeholders including those who are willing to invest in cattle development such as oil-palm estates.

Slaughter-houses are the places from where people get the meat for consumption, but the time is to utilize the by-products to increase the GDP’s rate from livestock. A field survey was conducted regarding usage of the by-products of slaughterhouses and/or meat selling centers in Dhaka city of Bangladesh. Data were collected from total 60 slaughterhouses and/or meat selling centers randomly from different part of Dhaka city consisting 20 large animal (cattle, buffalo), 20 small animal (goat, sheep) and 20 poultry bird (chicken, duck) slaughterhouses and/or meat selling centers. Following slaughtering process huge amount of different by-products are also produced that have good economic and nutritive value. The results revealed that edible by-products such as head trimmings, brain, tongue, heart, stomach, lungs, liver, pancreas, spleen, kidney and tail were used by 100% as human food. Inedible by-products had diversified uses but to some extent they were also rejected. However, no one of the inedible by-products was fully rejected. Among the inedible by-products the hides had a great industrial value. Poultry by-products like blood, intestines and feather wastes were generally found to utilize as fish feed. Most slaughterhouses were found to maintain moderate to poor hygienic conditions where very few maintained good condition. Almost two-third (61.67%) slaughterhouses were used water container as water supply followed by hose pipe (33.33%) and tape water (5%) for cleaning purpose. It can be concluded that by-products are valuable materials but due to lack of management and industrial mind slaughterhouses of the Dhaka city cannot utilize those materials. Therefore, proper usages of by-products can run a new prospective business in Bangladesh.

Problems associated with prediction of saleable meat yield, price haggling and monetary worth of cattle purchased due to difficulties in accurately relating visual appearance of animals and the weight with their price have always been in existence. This study was carried out to determine the accuracy in the use of heart girth tape as an alternative to the use of weighing bridge and crush, dressing percentage and expected cut yield from three indigenous breeds of cattle in Nigeria using linear body measurement. Thus, a total number of 51 healthy and mature White Fulani (n=17), Sokoto Gudali (n=17) and Red Bororo (n=17) cattle breeds were randomly purchased from Ilesha Baruba cattle market Kwara State, Kotangora cattle market, Niger State and Akinyele cattle market, Ibadan, Oyo state and were subjected to heart girth measurements. The study lasted for 32 weeks. Live weights of animals were determined at the point of purchase using a specialized measuring tape (girth tape) calibrated in kilogram (kg) and centimeter (cm).The live weights were recorded in kilogram which was used in price negotiation at the market. The live weight of the cattle ranged from 164 – 463 kg. The mean girth tape values were White Fulani (286.53 51.06)kg, Sokoto Gudali (293.35+77.51)kg and Red Bororo 261.88+60.65)kg respectively. Post slaughtering data collected were dressing percentage, weight of head(kg),neck(kg), shanks(kg), forearm(kg), thigh(kg),skin(kg),liver(kg),heart(kg), intestine(kg)and kidney(g).The study revealed that heart girth measurement had high correlation coefficient with live weight (r=0.99, p<0.001). This implies that the use of heart girth tape in weight prediction is accurate and reliable. There were significant (p<0.05) differences in the dressing percentage among the breeds (43.55-46.52) %. Significant (p<0.05) differences were observed in the cut yield percentage between Red Bororo (33.16 4.12) and other breeds but none between White Fulani (37.14 4.50)% and Sokoto Gudali (34.53 5.26)%.There were significant (p<0.05) differences in the head (13.52-13.42)kg, Neck (14.70-18.07)kg, left thigh (27.92-29.41)kg, right forearm (22.91-27.24)kg, left forearm (24.84-27.57)kg, liver (3.60 – 3.84)kg, skin (15.03 -15.39), shank (2.20-2.41)kg, tail (5.23-5.92)kg but none for right thigh, kidney and lungs among the breeds. The variations in the yield may be as a result of genetic, management, weight and age of the animals. It can be concluded that heart girth tape may be used where weighing crush is not available because of its accuracy and reliability. The study also revealed that White Fulani has higher meat yield than Sokoto Gudali and Red Bororo and will therefore be more profitable to cattle sellers, abattoir centers, slaughter houses andmeat shops.

Full textAbstract:
Background: Meat industries in developing countries including Bangladesh are found to be challenged by severe hygienic and sanitation problems which are associated with heavy bacterial load on the different sites of carcasses and meat. Objectives: The major objectives of this study were to determine the bacterial load at the different risk sites of bovine carcasses and identification of pathogenic bacteria as well as to assess the associated hygienic and sanitation practices with public health significance of the isolated bacteria. Materials and Methods: The study on bacterial load of bovine carcasses was conducted on 200 swab samples of different risk sites of 20 bovine carcasses in the different slaughterhouses of Barishal City Corporation during the period from April to October 2017. The aseptically collected swab samples from different sites of bovine carcasses were processed and analyzed individually by standard bacteriological procedures for Total viable count (TVC), Total coliform count (TCC), Total Staphylococcus count (TSC) and Total Salmonella count (TSAC) and the bacterial species were identified by the conventional aerobic cultural, morphological and biochemical tests. The hygienic status and practices of slaughterhouses and workers were evaluated through a structured questionnaire survey and also a visual inspection. Results: Staphylococcus aureus (78.5%), Salmonella spp. (64.5%) and Escherichia coli (64.0%) were found widely prevalent bacteria on the surface of freshly slaughtered bovine carcasses. The mean TVC of bacteria at pre-and post-washing of the different risk sites of carcasses including neck, shoulder, rump and their used knife and workers’ hand was calculated and highest one was recorded for neck at both pre (8.17 ± 1.22) and post (8.41 ± 0.92) washings. These TVC were found higher compared to standards set by WHO. The TSC was found highest at shoulder site at both pre (7.26 ± 0.94) and post (7.43 ± 1.02) washing, whereas the neck site was found highest contaminated with E. coli (6.69 ± 1.06 and 6.87 ± 1.04) and Salmonella spp.(5.73 ± 1.05 and 6.07 ± 0.92), respectively. The questionnaire survey and visual inspection of slaughter houses revealed that none of the slaughterhouse workers received any training on slaughterhouses management and hygiene, not used any head and hair covering, protective clothes and hand gloves whereas only 25.33% workers washed their hands and 34.67% used clean water at slaughterhouses during processing of carcasses and meat. Conclusions: The slaughtering of the animals on the ground and then skinning and evisceration in the same place under poor hygienic conditions are the major risk factors for heavy bacterial contamination of carcasses which has been recognized as a threat to food safety and consumers health to foodborne illness. Therefore, it requires a serious attention from all relevant authorities to apply and maintain the basic hygienic slaughterhouse practices to prevent the bacterial contamination of carcasses to prevent food borne illness. However, these data should serve as a baseline for future comparisons in measuring the bacteriological status of beef carcasses in other districts and further research works.

Background: Most of the developing countries including Bangladesh where humane treatment of slaughter animals is not satisfactorily practiced mainly due to poorly developed and implemented animal welfare legislation resulting in stress conditions and excessive suffering of animals. Objectives: The objective of this study was to assess the animal welfare knowledge and attitudes of animal transporters and butchers during transportation and slaughtering animals in local slaughter houses in Bangladesh Materials and Methods: This study was carried out from July to October 2017 at 40 local slaughter houses of 10 Upazilas in Mymensingh district. A pre-structured questionnaire was used to collect information from butchers at pre- and during slaughtering animals. The welfare data of 123 ruminant animals (84 cattle, 31 goats and 8 sheep) which were subjected to slaughter was collected by direct observation and examination. Results: Meat animals are usually purchased from the local market, some from farms and even from imported Indian cattle are usually transported from far away to slaughter houses. Significantly (p < 0.01) highest percentage of animals were transported by walking (42.28%), followed by truck (22.76%), pick-up van (20.33%), local vehicle (11.38%) and lowest by auto-rickshaw (3.25%). Small ruminants were kept in a lair-age for 1 to 2 days but most of the cattle were slaughtered upon arrival. Out of 123 animals investigated, 0.81 to 4.07% had lameness, 0.81 to 10.57% had skin lesions and 4.06 to 18.69% had dirty conditions in the different body regions. Diarrhea was recorded in 4.88% animals whereas 7.32% had nasal and 4.07% had ocular discharges. Lair-age was found in 85% slaughter houses with pacca (15.0%), kaccha (45.0%) and semi-pacca (40.0%) conditions but 80% had no bedding materials and 92.5% dirty floor condition. Mostly jute rope (89.43%) and halal method (100%) were used for casting and slaughtering of animals respectively without regular veterinary inspection. The stress caused by transportation and slaughtering of animals were not minimized due to lack of practice of animal welfare legislation in Bangladesh. Conclusions: The insufficient knowledge of animal transporters and butchers about animal behavior and animal welfare suggests that there is a need to improve animal welfare situation through training to the concerned people. Humane slaughter of animals may reduce the incidence of injury to the animals and less bruise to the carcasses that improve the meat quality.

Full textAbstract:
Introduction: Chicken meat is a source of protein in the human diet. Protein content and values define the quality of chicken meat. This research aimed to analyze variations of protein profiles in chicken breast muscles from different slaughtering houses by using proteomic strategies. Methods: Total proteins of chicken breast muscles from three different slaughtering houses (Sample A, Sample B and Sample C) were extracted and quantified by using Bradford assay. Then, the proteins were separated by SDS-PAGE to monitor the quality of extracted proteins. Protein profiles in different samples were compared by 2D-GE analysis. Results: The most highly expressed protein band was located between the molecular size of 37-50 kD in all samples and it was expected to be betaactin. While resolved in 2D-PAGE, differences in protein expression were observed between samples. There were three spots expressed with highest intensity in Sample B compared to others. The protein spot detected at pH 5.28 and the size range between 50- 75 kD was predicted to be NADPH-cytochrome P450 reductase (CPR), at pH 6.45 and molecular weight between 37-50 kD was expected to be creatine kinase M-type (M-CK) while at pH 6.78 and molecular size nearly 25 kD was expected to be αB-crystallin. Conclusions: It can be mentioned that these proteins could play a vital role in mechanisms that contribute to the poor quality of chicken meat.

Full textAbstract:
The aim of this study was to investigate the occurrence of antibiotic residues in the poultry meat. The effect of different thermal treatment on antibiotic residues were studied. Eighty Carcass of poultry were examined, the samples were taken from locally poultry Slaughter houses in Thamar city, from each Carcass three Samples were examined (muscles, liver, and kidneys). The test was done by direct microbiological method and by extraction method, Bacillus subtilus was selected for detection of antibiotic residues. Results revealed presence of antibiotic residues in muscles , livers and kidneys , and the percentage of this residues according to direct microbiological method were (6.3%) , (8.8%) and (12.5%) ,while the percentage of this residues according to extraction method were (5.0% ), (6.3%) and (11.3%) respectively. This study registered that the cooling temperature at 4 C˚ for a period of 3 days gave the affect on the remains of antibiotics in muscles and livers, the percentage of this residues according to direct microbiological method were (60.0%) and (57.1%), while the percentage of this residue according to extraction method were (50.0%) and (60.0%) respectively .Also the freezing at (-18) C˚ for a period of 4 week gave the affect on the remains of antibiotics in muscles, livers and kidneys, the percentage of this residues according to direct microbiological method were ( 60.0%) , (71.4%) and (80.0%) , while the percentage of this residue according to extraction method were (50.0%) , (80.0%) , and (77.8%) respectively .As for the cooking (boiling) temperature for 30 minutes for muscles and 15 minutes for livers showed full affect on the presence of remains of antibiotics for all samples undergoing examination in muscles and livers 100%, the result of examination was negative. This results highlights a potential public health problems and health risks to the consumers reflected in antibiotic resistance, teratogenicity, carcinogenicity, hepatic and renal failure. Veterinary control of withdrawal period between administration of antibiotic in poultry farm and slaughtering can reduce the occurrence of antibiotic residues and improve the quality of poultry meat
