This study characterized microbial transfer of vegetative bacteria (Listeria innocua and Escherichia coli), spores (Bacillus cereus), and a virus (MS2 bacteriophage), to large surfaces, using a “cloth and bucket” method with a commonly used quaternaryammonium compound (QAC) disinfectant (with or without 5% soil) and a phosphate-buffered-saline (PBS) control. We also characterized concentrations of organisms in the bucket solutions after wiping. With disinfectant (with or without soil), there was little transfer of vegetative bacteria. Transfer occurred readily with the PBS control (4.8 ± 1.0 and 3.3 ± 0.9 log CFU/surface for Listeria innocua and Escherichia coli, respectively). Spores were transferred efficiently, regardless of whether PBS or QAC was used or whether test was with or without soil (range, 6.5 to 7.8 log CFU/surface). MS2 bacteriophage appeared to be eliminated relatively quickly. When the QAC did not inactivate the organism (regardless of soil load), high microbial loads (> 87.9% of initial inoculum) were detected in the bucket solution after wiping experiments. This study suggests that reusable cloth can potentially promote contamination of surfaces, sometimes in the presence of disinfectant. This is concerning for food service and other settings in which disinfection practices rely on the cloth and bucket system.","PeriodicalId":38649,"journal":{"name":"Food Protection Trends","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45695788","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}

Few studies have used the Social Cognitive Theory to predict food safety behaviors, especially in independent ethnic restaurants. This study aimed to determine whether self-efficacy, self-regulation, outcome expectations, and environmental determinants are predictive of self-reported food safety behaviors through examining the behavioral intentions of food handlers in independent Chinese and Mexican restaurants. A questionnaire was developed and self-administered. It was translated to Chinese and Spanish and backtranslated to English to ensure accuracy. A multistage random sampling technique was utilized to collect data onsite, targeting a minimum of 250 food handlers from independent Mexican and Chinese restaurants. A total of 204 food handlers responded; 201 responses were usable, for a response rate of 80.4%. Multiple regression and mediation analyses were used to analyze the data. Only self-regulation, environmental determinants, and outcome expectations were statistically significant predictors of food safety behavioral intentions. Behavioral intentions were a significant mediator of the relationships between all predictors and self-reported food safety behaviors. The findings suggest that self-regulation, outcome expectations, and environmental factors in the form of equipment and supplies can promote positive food safety behaviors through behavioral intentions. INTRODUCTION Ethnic restaurants are defined as those that serve food from countries other than the traditional cuisine of the host country (18). Ethnic restaurants, especially Chinese, Italian, and Mexican have gained popularity and have become mainstream in the diet of most Americans (3, 47, 51). The ethnic food market continues to grow, with Mexican food having 62% of the market share (45). The increased interest in ethnic food in the United States has been driven by the diverse population, the growing number of immigrants who seek their traditional food, and young people who like to try new and different foods (57, 64).","PeriodicalId":38649,"journal":{"name":"Food Protection Trends","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46998542","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}

This paper seeks to define the flow of vegetable crops within the vegetable value chain in Cambodia and provides insight into potential contamination points for bacterial hazards. A total of 102 vegetable farmers, 21 vegetable collectors, 30 vegetable distributors, and 100 vegetable vendors were interviewed about sanitation and hygiene practices. Visual assessments of vegetable handling practices and market conditions, as they pertain to food safety, were also conducted at the market level. Findings showed several deficiencies in food safety practices, including (1) the use of inadequately composted manure and improper harvest intervals after manure application; (2) the common practice of cutting out bruised portions of vegetables; (3) a lack of cool storage; (4) a lack of hygienic practices during transport and marketing, and (5) a lack of adequate infrastructure (tables, roofing, etc.) and hygienic infrastructure (functioning drains, cleanable surfaces, etc.) within markets. These factors increase the likelihood of bacterial contamination of vegetables, posing a threat to public health and weakening consumer confidence in vegetables produced and sold in Cambodia. These findings can support the development of suitable food safety intervention strategies for Cambodia.","PeriodicalId":38649,"journal":{"name":"Food Protection Trends","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43287628","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}
