A majority of foodborne illnesses result from inappropriate food handling practices. One proven practice to reduce pathogens is to perform effective hand-hygiene before all stages of food handling. In this paper, we design a multi-camera system that uses video analytics to recognize hand-hygiene actions, with the goal of improving hand-hygiene effectiveness. Our proposed two-stage system processes untrimmed video from both egocentric and third-person cameras. In the first stage, a low-cost coarse classifier efficiently localizes the hand-hygiene period; in the second stage, more complex refinement classifiers recognize seven specific actions within the hand-hygiene period. We demonstrate that our two-stage system has significantly lower computational requirements without a loss of recognition accuracy. Specifically, the computationally complex refinement classifiers process less than 68% of the untrimmed videos, and we anticipate further computational gains in videos that contain a larger fraction of non-hygiene actions. Our results demonstrate that a carefully designed video action recognition system can play an important role in improving hand hygiene for food safety.

ABSTRACT Food handling across the custody chain from production to consumption is one of the most important stages in which microbes can enter food from infected food handlers or due to cross-contamination. The wholesale produce market (WSPM), located in Doha, Qatar, is a good example of a custody chain in which a large amount of produce from different origins are purchased daily by restaurants, retailers, and individuals. However, no information is available on the food handling practices applied at the WSPM. Hence, this study was conducted to assess the self-reported hygiene practices and food safety knowledge of produce handlers at the WSPM as a baseline for food safety outreach. One hundred twenty produce handlers participated in this study to complete a structured questionnaire assessing food safety knowledge and hygiene practices. In addition, survey respondents' hands were swabbed to determine microbiological hand hygiene levels. Survey results revealed that none of the produce handlers had food safety knowledge or received training on safe produce handling practices. The median age group was 31 to 40 years, and over 57% had less than high school education. The level of self-reported knowledge on “food safety practices” displayed by produce handlers was not influenced by demographically based differences (e.g., age and years of experience), except education level. Note that 77% of produce handlers claimed to wash their hands four times per day; however, this good self-reported practice was not reflected in the microbial assessment of produce handlers' hands that had total aerobic and coliform counts ≥2 log CFU/cm2. Bacillus circulans (40%), Staphylococcus sciuri (25%), and Klebsiella pneumoniae (17%) were the most common bacteria isolated from produce handlers' hands. These findings may help public health agencies in Qatar establish guidelines for compulsory on-site training for produce handlers to improve knowledge on safe produce handling. HIGHLIGHTS

In several areas, Kentuckians practice more risky health behaviors than most of the rest of the nation. The Health Belief Model states that individuals with lower perceived risks practice less healthy behaviors. This study sought to determine if this was true for food safety by assessing food safety perceptions and behaviors of Kentucky consumers. Data were collected through a telephone questionnaire based on a survey by the U.S. Food and Drug Administration; 728 respondents participated. Food safety perceptions were analyzed by examining participants' responses to confidence in the safety of the food supply, perception of likelihood of people becoming sick because of foodborne illness, and perception of where food safety problems are most likely to occur. Significant differences were found in food safety perceptions for age, gender, household income, education, and employment in the food industry. Analysis of food safety behaviors revealed differences in food handling behaviors for gender, education level, household income, race, and households with a member aged 65 years or older. Significant relationships were found between respondents' food safety perceptions and behaviors. In general, Kentucky consumers who perceived higher risks exhibited safer food handling behaviors. Strategies to increase the understanding of real and perceived food safety risks in the home combined with strategies that target specific demographic groups may be the most effective approach to improve food handling practices. A better understanding of consumers' food safety risk perceptions and behaviors could lead to more effective food safety education materials and messages.

Foodborne diseases have always been linked to numerous food manufacturing elements and home practices of purchasers and the latter does play a critical role in disease prevention. Consumers have the ultimate responsibility for handling and storing food safely and take adequate safety precautions when preparing and consuming food at home to avoid health related problems associated with microbial hazards. The objectives of this survey were to evaluate current knowledge of consumers pertaining to food hygiene and food safety concepts as well as to assess food handling practices that residents adopt to reduce microbial hazards in the domestic environment. A sample of 300 Mauritian residents were selected to participate in a questionnaire based survey. Questions in the questionnaire were based on hygienic practices with respect to food handling, food safety and personal hygiene. SPSS (Statistical Package for Social Sciences) was used to analyze the results and Microsoft excel was used to generate pie charts, and bar charts. The results obtained demonstrated that the level of knowledge pertaining to food safety and food hygiene and how to reduce microbial hazards were above average. Majority of the residents were knowledgeable about major aspects related to proper food handling behaviors but need more education pertaining to the use of thermometers to check for food temperature. The nature of the risk, personal and environmental factors (psychological, demographic and socio-economic factors, cultural and economic) were found to be the factors affecting food safety behaviors among consumers. Consumers can become more motivated to improve their behaviors if they are made aware of the impact of risky practices. Although, most consumers had basic knowledge pertaining to food safety, food hygiene and food handling practices, it is important to continually inform consumers about safe food handling practices through various channels.

Food safety has become a global issue due to the morbidity and mortality associated with it, particularly in developing countries. The objective of this community-based study is to examine food safety practices and its associated factors among postnatal mothers in the Western Region of Ghana. A cross-sectional survey study was conducted from August 1 2019 to January 31, 2020 from which data was obtained from the postnatal mothers ( N = 300 ). The data was analysed using SPSS v.23. The findings suggest that majority (86%) of the respondents exhibited good food handling practices. Also, 66.3% and 91.7% of the respondents exhibited good food preparation and proper storage practices, respectively. Results also revealed that the odds of performing good handling practice among respondents within the age group of 36-45 years were five times higher compared to those within the age group of 18-25 years [ OR = 4.92 (95% CI: 1.44–16.86), p = 0.011 ]. Moreover, respondents who had tertiary education qualifications were more likely to have proper food handling practices compared to those with primary education [ OR = 0.27 (95% CI: 0.09–0.71), p = 0.009 ]. These findings provide useful insights for policy directions. The government of Ghana and other stakeholders should develop a communication strategy to increase and sustain publicity and education on food safety particularly to postnatal mothers and the citizenry in general.

Food safety training has been the primary avenue for ensuring food workers are performing proper food handling practices and thus, serving safe food. Yet, knowledge of safe food handling practices does not necessarily result in actual performance of these practices. This research identified participating food service employees' level of agreement with four factors of motivation (internal motivations, communication, reward-punishment, and resources) and determined if respondents with different demographic characteristics reported different motivating factors. Data were collected from 311 food service employees who did not have any supervisory responsibilities. Intrinsic motivation agreement scores were consistently the highest of all four motivational factors evaluated and did not differ across any of the demographic characteristics considered. In contrast, motivation agreement scores for communication, reward-punishment, and resources did differ based on respondents' gender, age, place of employment, job status, food service experience, completion of food handler course, or possession of a food safety certification. In general, respondents agreed that these motivation factors influenced their likelihood to perform various safe food handling procedures. This research begins to illustrate how employees' demographic characteristics influence their responses to various motivators, helping to clarify the complex situation of ensuring safe food in retail establishments. Future research into why employee willingness to perform varies more for extrinsic motivation than for intrinsic motivation could assist food service managers in structuring employee development programs and the work environment, in a manner that aids in improving external motivation (communication, reward-punishment, and resources) and capitalizing on internal motivation.

Street foods have become a major source of cooked food for most households and individuals in many developing countries including Ghana. However, the rising concern about food-borne illness has questioned the knowledge of the street food vendors to constitute safety practices for food handling. This study assessed the knowledge of street food vendors on food safety and food-handling practices in the Ejisu-Juaben Municipality of Ghana. The study used a cross-sectional mixed approach involving 340 participants selected by simple random sampling. A structured questionnaire and an observational checklist were used to collect data and analyzed using STATA version 12. The results indicated that 98.8% of the food vendors had good knowledge on food safety and handling. The knowledge on food safety was associated with training (p value ≤0.011), license status (p value ≤0.002), marital status (p value <0.001), and religion (p value ≤0.038). Good food-handling practices were associated with training (p value ≤0. 001) and license (p value ≤0.002) and not their educational levels. The study found training of food vendors as the most effective way to increase knowledge on food safety and enhance food-handling practices. The study recommended for collaborations of municipal assemblies with other agencies to strengthen, sustain, and organize regular training programs for new entrants and existing food vendors as well as retraining of trainers to equip them adequately with knowledge and skills to enable them effectively facilitate training programs for food vendors.

<p class="1"><span lang="EN-US">The purpose of this research was to analyze the perceptions and practices of participants involved in safe food handling. The sample was composed by 204 participants. To assess behavior, knowledge and psychosocial factors, the instrument used was divided in six topics: sociodemographic characteristics; behavioral measures regarding safe food production; measures about knowledge and practices in pest control and food purchase; Food Safety scale with two factors and Cronbach's alpha of 0.75; Credence declaration scale with three factors and Cronbach's alpha of 0.78, both scales with seven points, Likert type; Self-efficacy scale with one factor and Cronbach's alpha of 0.86, also Likert type with five points. A linear model of multiple variance analysis was used to evaluate if the variables gender, age, income, education and professional experience were used to determine the behavioral, knowledge and psychosocial measures. When the detected differences were significant, a post-hoc analysis was used with the Tukey adjustment. The knowledge about safe food production and food poisoning showed that 95.1% of participants consider <em>very important</em> hygiene precautions in food preparation in their homes; 30.4% of participants said that they or someone in their family have developed symptoms related to food poisoning in the last 12 months. The data obtained for self-efficacy showed significant differences for the variables gender, age and education. Women and college graduates replied that they <em>Are Sure they Can Do That </em>when asked about the execution of tasks that promote food safety. </span><span lang="EN-US">These results substantiate the need for educational initiatives tailored to develop the food safety knowledge and food-handling practices in Brasil.</span><strong></strong></p>

ABSTRACT The incidence of foodborne illness is higher in older adults because of their increased susceptibility; therefore, food safety practices are important. However, inadequate knowledge and negative attitudes toward food safety have been reported, which may increase use of unsafe food handling practices. Data on the actual food safety behaviors of older adults are lacking. In this study, food safety practices of older adults were observed and linked to microbiological analysis of kitchen surfaces to identify suspected routes of contamination. Older adults (≥60 years, n = 100) prepared a set meal in a model domestic kitchen sanitized according to a validated protocol to ensure minimal and consistent microbiological loads. Food safety behaviors were observed using ceiling-mounted cameras and recorded using a predetermined behavioral checklist. Surface microbiological contamination also was determined after food preparation. Overall, older adults frequently implemented unsafe food handling practices; 90% failed to implement adequate hand decontamination immediately after handling raw chicken. For older adults who used a larger number of adequate hand decontamination attempts, microbiological contamination levels in the kitchen following the food preparation session were significantly lower (P &lt; 0.001). The novel utilization of behavioral observation in conjunction with microbiological analysis facilitated identification of potentially unsafe food handling practices as suspected routes of microbiological cross-contamination in a model domestic kitchen. Findings indicate the potential impact on domestic food safety of unsafe food handling practices used by older adult consumers. This innovative approach revealed that a large proportion of older adults implement behaviors resulting in microbiological cross-contamination that may increase the risk of foodborne illness in the home.

ABSTRACT Pet food has been identified as a source of pathogenic bacteria, including Salmonella and Escherichia coli. A recent outbreak linked to Salmonella-contaminated pet treats infected &gt;150 people in the United States. The mechanism by which contaminated pet food leads to human illness has not been explicated, and pet owners' food safety knowledge and their pet food handling practices have not been reported. This study was conducted to evaluate pet owners' food safety knowledge and pet food handling practices through an online consumer survey. The survey consisted of 62 questions and assessed (i) owners' food safety knowledge and pet food handling practices; (ii) owners' interaction with pets; and (iii) owners' risk perception related to their own health, their children's health, and their pets' health. The survey was pilot tested among 59 pet owners before distribution to a national consumer panel managed by Qualtrics XM (Provo, UT). All participants (n = 1,040) were dog and/or cat owners in the United States. Almost all pet owners (93%) interacted with their pets, and most cuddled, allowed their pets to lick them, and slept with their pets. Less than one-third of pet owners washed their hands with soap after interacting with their pets. Over half (58%) of the owners reported washing their hands after feeding their pets. Most pet owners fed their pets dry pet food and dry pet treats. Some fed their pets raw meat or raw animal product diets because they believed these diets to be beneficial to the pet's overall health. Many owners (78%) were unaware of pet food recalls or outbreaks associated with foodborne pathogens. Less than 25% considered dry pet foods and treats as a potential source of foodborne pathogens. Pet owners were more concerned when seeing news about pets becoming ill from pet food and less concerned when seeing news about people becoming ill from pet food. The findings of this study indicated the need for consumer education about handling pet food. These results can help researchers develop more accurate risk assessment models and consumer education messages related to pet food handling. HIGHLIGHTS
