Though numerous interventions have been implemented in school foodservice, foodborne illness continues to be an issue in the United States. Ultimately, an understanding of recurring food safety violations would inform development of targeted food safety training interventions that could mitigate the number of foodborne illness outbreaks. The aim of this study was to analyze food safety violation trends from 2010 to 2019 in a large urban school system to explore research and educational opportunities. Over 20% of food safety inspections resulted in failure; 9.0% of all violations were critical, 11.9% were serious, and 79.1% were minor. These findings underscore the need to reevaluate current food safety educational interventions and food safety handling practices. Key critical and serious violation trends were lack of food safety knowledge, lack of temperature controls throughout the food preparation process, and lack of appropriate supplies. Recurring minor violations pertained to cleanliness of the facility (ventilation, flooring,","PeriodicalId":38649,"journal":{"name":"Food Protection Trends","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41570176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The OFRR tool was created to align the FSMA PSR provisions with relevant farming practices in time and space; it also linked recommendations for implementation of PSR requirements and offered evaluation criteria to assess PSR compliance before inspection. The developed tool is composed of a decision tree, walk-around questions, and a resource manual. The tool is the foundation of the training curriculum. The tool and curriculum were piloted and evaluated by participants to inform additional development of the final product. OFRR trainings were held nationally, and participants were trained on how to use the tool to conduct a confidential on-farm assessment of a farm’s readiness for a FSMA PSR inspection. The tools and training have had a beneficial impact on participants understanding of the FSMA PSR, have increased the assessors’ ability to apply the PSR to the farm, and have developed trained assessor teams that are able to evaluate inspectional readiness in their home state.","PeriodicalId":38649,"journal":{"name":"Food Protection Trends","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49142372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UV light is a suitable alternative for treating drinking water but is not always effective for surface irrigation water due to interference caused by turbidity and high microbial loads. The effectiveness of UV treatment for reducing Escherichia coli and Salmonella in surface water used in agriculture was evaluated. Six pond water samples were collected on each of 16 sampling dates over a 3-year period. On each corresponding testing date, three samples were inoculated with Salmonella enterica serovars Hartford, Montevideo, and Gaminara and the other three samples were inoculated with E. coli ATCC 25922, targeting a concentration of 7 log CFU/mL. Inoculated water was UV treated with a commercially available juice processing UV device at a constant UV dose of 14.2 mJ/cm2 and a turbulent flow regime. The effects of date, initial bacterial counts, and water pH and turbidity on log reductions of both microorganisms were determined. Initial bacterial counts and test date significantly predicted microbial reduction (multivariate P < 0.001), but neither pH nor turbidity influenced microbial reductions (P > 0.05). UV treatment reduced both Salmonella and E. coli by a mean of >6 log CFU/mL.","PeriodicalId":38649,"journal":{"name":"Food Protection Trends","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45680745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CDC created 27 Facebook posts for nine multistate foodborne outbreaks (one to eight posts per outbreak), and 2,612 comments were analyzed. The CDC used two Web tools to deliver outbreak information: food safety alerts (FSAs) and investigation notices (INs). Qualitative analyses were conducted separately for Facebook posts resulting from FSAs and INs. Using an inductive coding approach, we identified nine categories of comments: information sharing (e.g., tagging others), actions (e.g., discarding contaminated food), convictions and beliefs (e.g., food-related preconceived notions), questions (e.g., clarifying outbreak location), emotional responses (e.g., worry), blame (e.g., responsibility for outbreak), food specific (e.g., repackaging ground beef and losing identifying information), promoting another cause (e.g., vaccine hesitancy), and unrelated.

The proximity of animals to production areas, animal types and densities, an animal operation’s management practices, and weather conditions are some of the areas explored by researchers to better understand how pathogens contaminate unharvested crops. Water, inputs, airborne particulates, wildlife, and insects may serve as vectors linking pathogens from their animal hosts to produce production areas. Studies have shown a positive correlation between rainfall and pathogen concentrations in agricultural water downstream from animal operations. Bacteria attached to airborne particulates can be deposited onto crops or open water sources. Wildlife and insects share habitat with domesticated animals in rangelands, pasture settings, pens, and feedlots. Plant conditions (injuries, disease) and characteristics (surface topography, genetic traits, age, native microbiota) and environmental conditions (relative humidity, moisture, temperature) play a major role in determining pathogen survival on unharvested produce. This article explores recent research findings elucidating human pathogen dispersion and deposition, subsequent transfer from animals to crops, and the various environmental risk factors along the way that play a role.","PeriodicalId":38649,"journal":{"name":"Food Protection Trends","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42664802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Listeria 5-point control plan to manage the occurrence of Listeria in high hygiene food manufacturing areas has been developed and trialed in the United Kingdom and Ireland since 2016; it comprises these points: • Prevent entry of Listeria into high hygiene food manufacturing areas using effective barriers. • Ensure that the high hygiene manufacturing infrastructure (building structure, equipment, and utensils) cannot harbor and/or allow the growth of Listeria (Listeria sources). • Ensure that high hygiene good manufacturing practices limit the cross-contamination vectors that can carry Listeria from sources to product or product- contact surfaces. • Design an effective cleaning and disinfection program that will kill or remove any Listeria that has entered the high hygiene area since the previous cleaning program. • Provide an environmental monitoring and microbiological verification sampling program that monitors and verifies Listeria control procedures.

With increased Salmonella testing standards required by the U.S. Department of Agriculture (USDA) on the horizon for the pork industry, it is important to improve understanding of Salmonella contamination within a variety of swine tissues, including lymph nodes. This study was designed to provide preliminary information about Salmonella prevalence in multiple lymph nodes within market hog carcasses at slaughter. From each carcass (n = 50), four lymph nodes were aseptically collected at slaughter: mesenteric, tracheobronchial, inguinal, and subiliac. A total of 197 lymph nodes were analyzed, with an overall Salmonella prevalence of 21.8% (n = 43). Salmonella was detected in the lymph nodes of 62% (n = 31) of carcasses, with 21.6% (n = 11) of carcasses harboring Salmonella in two or more lymph node types. Although not statistically significant (P = 0.1167), Salmonella prevalence did vary based upon lymph node type (mesenteric, 34%; inguinal, 18.4%; subiliac, 18.4%; tracheobronchial, 16.3%).
