AbstractFarmers of Aranaputa Valley village in the rural interior of Guyana rely on peanut as their primary cash crop. The focus of this study was to document current peanut farming practices in this community. Household surveys and informal interviews were conducted in 2012 to evaluate the 2011 farming season. Farmers relied on distant markets or the community development council for agricultural inputs. More than half of farmers were selling their peanut crop to truck drivers who pass through their community, while 35% sold their peanut crop to the local peanut butter cottage industry. Interviewees indicated the desire for new peanut varieties to produce in their farming systems, suggesting the potential for adoption of new varieties recently evaluated in the region. These results suggest a need for additional agricultural research in the region and development projects that can assist in closing the gap of market accessibility; both for inputs and farm sales.

Abstract The detection of food allergens has been a challenge because of the increasing need to ensure the absence of undeclared allergens in foods. The current trend in the detection of some food allergens, like peanuts, is based on the detection of multiple allergenic and nonallergenic proteins, and this is the approach that kit manufacturers have adopted. Because commercial kits differ in their ability to detect allergens, regulatory agencies, the food industry, and kit manufacturers are working together to standardize the detection methods. Three kits for the detection of peanuts have been evaluated for performance by the AOAC Research Institute. For this evaluation, a peanut butter suspension was used as a reference material. Several kit components contribute to between-kit analytical variation, even when the same sample is used. One component of commercial kits, which may be contributing to this variability, is the sample extraction buffer. In this study, differences in extractability of 3 allergenic foods were evaluated by using 4 different extraction buffers. The conclusion is that optimum allergen extractability was buffer-dependent, and no single buffer is appropriate for use as a universal extraction solution for all allergenic foods. Therefore, a thorough evaluation of sample preparation buffers needs to be performed for every individual allergenic food. In light of the results obtained, the current approach used for detection of peanut allergens based on the detection of multiple allergenic and nonallergenic proteins is being analyzed.

ABSTRACT Recent recalls and outbreaks due to foodborne pathogens in thermally processed low-moisture foods highlight the need for the food industry to validate their thermal process. The purpose of this study was to validate baking as an adequate lethality step in controlling Salmonella and Listeria monocytogenes during the production of peanut butter (PB)–filled pretzels and whole wheat (WW) pita chips. Two dough types, PB-filled pretzel and WW pita chip with varying water activities (0.96 to 0.98), were inoculated (target level, ∼108 to 109 CFU/g) with a multistrain cocktail of Salmonella and L. monocytogenes in separate trials and were baked at 300°F (148.9°C) and 350°F (176.6°C) for 0, 5, 10, 17, 25, and 30 min. Following baking, samples were rapidly cooled and analyzed for Salmonella and L. monocytogenes by the pour plate method. Uninoculated samples were analyzed for total viable aerobic plate count (APC) and Enterobacteriaceae counts. Water activity analysis was also performed. The experiment was replicated three times. Nonlinear regression was used to estimate the baking times required to achieve a minimum of 4- and 5-log reduction in APC, Salmonella, and L. monocytogenes. A 4- and 5-log reduction in APC was predicted following a treatment at 350°F for 3.3 and 5.6 min in WW pita chip product, respectively. Following a treatment of 350°F for 10 and 25 min, Enterobacteriaceae and APC counts were below the detection limit (<1 log CFU/g), respectively, in all of the PB-filled pretzel samples. Salmonella and L. monocytogenes counts decreased with increasing baking time regardless of the temperature used. Significant reductions (≥5-log reduction) were estimated in Salmonella and L. monocytogenes in product baked at 350°F for 15.5 and 17.5 min in WW pita chip dough and PB-filled pretzel dough, respectively. Both pathogens were below the detection limit (<1 log CFU/g) in PB-filled pretzel and WW pita chip products under baking conditions of 350°F for 25 and 30 min, respectively. This study demonstrates that PB-filled pretzel and WW pita chip products, when baked to saleable quality, will not present a public health risk from the standpoint of Salmonella or L. monocytogenes.

Small amounts of sesame can trigger allergic reactions in sesame-allergic patients. Because sesame is a widely used food ingredient, analytical methods are needed to support quality control and food safety programs in the food industry. In this study, polyclonal antibodies against sesame seed proteins were raised, and an enzyme-linked immunosorbent assay (ELISA) was developed for the detection and quantification of sesame seed residue in food. A comparison was made between this ELISA and other assays, particularly focusing on recovery of sesame seed residue from different food matrices. The developed ELISA is sensitive with a lower limit of quantification of 0.5 ppm and shows essentially no cross-reactivity with other foods or food ingredients (92 tested). The ELISA has a good recovery for analyzing sesame-based tahini in peanut butter, outperforming one other test. In a baked bread matrix, the ELISA has a low recovery, while two other assays perform better. We conclude that a sensitive and specific ELISA can be constructed based on polyclonal antibodies, which is suitable for detection of small amounts of sesame seed relevant for highly allergic patients. Furthermore, we conclude that different food products may require different assays to ensure adequate quantification of sesame.

Abstract The VIDAS®Salmonella (SLM) Easy Salmonella method is a specific enzyme-linked fluorescent immunoassay performed in the automated VIDAS instrument. The VIDAS Easy Salmonella method is a simple 2-step enrichment procedure, using pre-enrichment followed by selective enrichment in a newly formulated broth, SX2 broth. This new method was compared in a multilaboratory collaborative study to the U.S. Food and Drug Administration's Bacteriological Analytical Manual, Chapter 5 method for five food matrixes (liquid egg, vanilla ice cream, spinach, raw shrimp, and peanut butter) and the U.S. Department of Agriculture's Microbiology Laboratory Guidebook 4.04 method for deli turkey. Each food type was artificially contaminated with Salmonella at three inoculation levels. A total of 15 laboratories representing government, academia, and industry, throughout the United States, participated. In this study, 1583 samples were analyzed, of which 792 were paired replicates and 791 were unpaired replicates. Of the 792 paired replicates, 285 were positive by both the VIDAS and reference methods. Of the 791 unpaired replicates, 341 were positive by the VIDAS method and 325 were positive by the cultural reference method. A Chi-square analysis of each of the six food types was performed at the three inoculation levels tested. For all foods evaluated, the VIDAS Easy SLM method demonstrated results comparable to those of the reference methods for the detection of Salmonella.

A snack made of 36% by byproducts of grape and tomato pomaces was developed, also including other ingredients, such as oats, chia, quinoa, honey and peanut butter. The recipe was defined as tasty and healthy by a focus group. The snack was produced by using forced air at three different drying temperatures (50 °C, 60 °C and 70 °C). The Newton, Page, Henderson and Pabis, and Midilli–Kucuk models fit the drying curves well. The average values for the Newton’s model drying constants were k50 = 2.71 × 10−1 ± 3 × 10−3 min−1, k60 = 2.76 10−1 ± 4 × 10−3 min−1 and k70 = 3.91 × 10−1 ± 8 × 10−3 min−1 at 50 °C, 60 °C and 70 °C, respectively. The product’s quality was assessed in terms of storage with respect to water activity and texture (hardness, springiness, cohesiveness, chewiness and resilience). There were no differences among the three tested processing temperatures in terms of their influence the final product’s quality. As there were no significant differences between initial and final water activity and texture attributes at any temperature and they were mainly unaltered during storage, the snack bar was considered stable during this period. This new snack, which includes byproducts from the food industry, reduces food waste and contributes to a circular economic model, simultaneously presenting environmental and economic advantages.

Abstract Salmonella, one of the most common causes of foodborne illness, is a significant public health concern worldwide. There is a need in the food industry for methods that are simple, rapid, and sensitive for the detection of foodborne pathogens. In this study, the Samsung Salmonella Detection Kit, a realtime PCR assay for the detection of Salmonella, was evaluated according to the current AOAC guidelines. The validation consisted of lot-to-lot consistency, stability, robustness, and inclusivity/exclusivity studies, as well as a method comparison of 10 different food matrixes. In the validation, the Samsung Salmonella Detection Kit was used in conjunction with the Applied Biosystems StepOnePlus™ PCR system and the Samsung Food Testing Software for the detection of Salmonella species. The performance of the assays was compared to the U.S. Department of Agriculture/Food Safety and Inspection Service-Microbiology Laboratory Guidebook (USDA/FSIS-MLG) 4.05: Isolation and Identification of Salmonella from Meat, Poultry, Pasteurized Egg, and Catfish and the and U.S. Food and Drug Administration/Bacteriological Analytical Manual (FDA/BAM) Chapter 5 Salmonella reference methods. The validation was conducted using an unpaired study design for detection of Salmonella spp. in raw ground beef, raw pork, raw ground pork, raw chicken wings, raw salmon, alfalfa sprouts, pasteurized orange juice, peanut butter, pasteurized whole milk, and shell eggs. The Samsung Salmonella Detection Kit demonstrated lot-to-lot consistency among three independent lots as well as ruggedness with minor modifications to changes in enrichment incubation time, enrichment incubation temperature, and DNA sample volume for PCR reaction. Stability was observed for 13 months at –20°C and 3 months at 5°C. For the inclusivity/exclusivity study, the Samsung Salmonella Detection Kit correctly identified 147 Salmonella species isolates out of 147 isolates tested from each of three different enrichment broths (a total of 441 isolates detected), and correctly excluded all 31 nontarget strains analyzed. For the method comparison, statistical analysis was conducted according to the Mantel-Haenszel Chi-square formula for unpaired test portions, and there was no significant difference in the number of positive samples detected between the Samsung Salmonella Detection Kit and the USDA/FSIS-MLG and FDA/BAM reference methods for all 10 food matrixes.

Abstract Magic bullets refer to single interventions, vertically delivered (i.e. from the centre), expected to have a dramatic effect, and often in practice circumventing or displacing more locally appropriate and sustainable activities. Once policies have defined intended outcomes – here childhood malnutrition is considered – decisions on programme specifics should take full account of trade-offs (including opportunity costs), and these decisions at present are often unduly influenced by vested interests. Magic bullets have times-and-places where they may be effective. These may get superseded, for example with changing disease patterns or other conditions, or because of new technologies. Regular transparent assessments of current applicability, with some estimate of benefits and costs, are essential, but uncommon. Six examples of single purpose interventions are summarized considering times-and-places: protein supplements, infant formula, high dose vitamin A capsules (HDVAC), the vitamin supplement industry, ready-to-use therapeutic foods (RUTFs), and oral rehydration therapy (ORT). HDVAC and RUTFs are compared to community-based nutrition programmes. Protein is rarely the binding constraint in preventing or treating infant and child malnutrition. Infant formula is hardly ever to be preferred to breastfeeding; and in poor countries with inadequate hygiene its use carries much increased mortality risk. HDVACs were shown to have a mortality impact in the 1980’s and early 90’s, leading to global programs now covering a reported 200 million children; however recent studies have shown that this effect is no longer seen, but policies and programmes have yet to change in most countries. The vitamin supplement industry is included as it contributes to misguided views of nutrition and health, which should be mitigated. RUTFs are very useful for the narrowly defined group of children with severe acute malnutrition still with an appetite (most severely malnourished children have a poor or zero appetite, and require liquid diets first). However, the off-label use of these sweetened peanut butter pastes for moderately (or less) malnourished children is becoming widespread: it has many immediate and long-term disadvantages, including on children’s food preferences; local foods, maybe enhanced with micronutrient mixes, are far preferable, including for rehabilitation of severely malnourished children. Oral rehydration provides a further example of where local solutions are preferable – but still seldom applied. Community-based programmes have known effectiveness, are more sustainable than magic bullet approaches, and in all the examples above can contribute to local problem solving. The implications for resource allocations are that shifting resources from magic bullet programmes to local, community- (and facility-) based activities will have many advantages. While cost estimates are hard to find, it seems that some such as HDVAC cost around $1 per child per year, and RUTFs for SAM around $5 per child per year (in the overall population; per SAM case treated the estimated cost is more than $100). Effective community-based programmes cost about $10 per child per year, but address not one but most of the nutrition problems faced by children in those communities. Major donors have allocated 50% or so of their budgets to such supplies, and these funds go to the manufacturers in the rich countries, not to the countries in need. Allocation of resources to the countries themselves, and to local activities, could amount to billions of dollars, leading to improved nutrition, if single purpose interventions like HDVAC and RUTFs were no longer soaking up time, efforts of frontline workers, and funds.
