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 < 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.

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.

Background. Foodborne diseases remain a major public health problem globally, but the problem is severe in developing countries like Ethiopia. The objective of this study was to assess food safety practices and associated factors among food handlers of Fiche town. Methods. A cross-sectional study was conducted among 422 food handlers working in food and drink establishments. The data were collected using a structured questionnaire and observational checklist. Data were entered and coded into SPSS for analysis. Multivariable logistic regression was used to identify the predictor variables associated with the practice of food handlers ( p < 0.05 ). Result. 61.6% of food handlers knew the potential risk of contaminating food with dirty hands, and 70% washed hands with soap before working with food. 52.8% of food handlers covered the hair with restraints. 66.8% of food handlers used outer garments, and the majority of food handlers (71.1%) had a trimmed fingernail. Two hundred thirteen (50.5%) of food handlers had good food handling practices. Medical checkup (AOR = 3.16; 95% CI 1.89, 5.26), sanitary inspection (AOR = 1.76; 95% CI 1.16, 2.69), knowledge (AOR = 2.31; 95% CI 1.53, 3.48), service year (AOR = 3.11; 95% CI 1.53, 6.31), and educational status (AOR = 3.42, 95% CI 1.29, 9.04) were found to be significantly associated with food handling practices. Conclusion. The food handlers should take various training concerning food hygiene and safety to enhance their knowledge and practice. Regular sanitary inspection of food and drink establishments is recommended.

An informed consumer can compensate for several potential food safety violations or contaminations that may occur earlier in the food production chain. However, a consumer can also destroy the work of others in the chain by poor food handling practices, e.g., by storing chilled ready-to-eat foods at abusive temperatures. To target risk-reducing strategies, consumer groups with high-risk behavior should be identified. The aim of this study was to identify demographic characteristics associated with high-risk food handling practices among Norwegian consumers. More than 2,000 randomly selected Norwegian consumers were surveyed, and the results were analyzed with a risk-based grading system, awarding demerit points for self-reported food safety violations. The violations were categorized into groups, and an ordinary multiple linear regression analysis was run on the summarized demerit score for each group and for the entire survey group as a whole. Young and elderly men were identified as the least informed consumer groups with the most unsafe practices regarding food safety. Single persons reported poorer practices than those in a relationship. People with higher education reported poorer practices than those with lower or no education, and those living in the capital of Norway (Oslo) reported following more unsafe food practices than people living elsewhere in Norway. Men reported poorer food safety practices than women in all categories with two exceptions: parboiling raw vegetables before consumption and knowledge of refrigerator temperature. These findings suggest that risk-reducing measures should target men, and a strategy is needed to change their behavior and attitudes.

Purpose Medeiros et al. (2001) estimate 3.5 million cases of foodborne illness in the USA annually are associated with inadequate cooking of animal foods or cross-contamination from these foods. Past research shows home food handling practices can be risk factors for foodborne illness. The purpose of this paper is to evaluate the communication of food safety guidance, specifically safe endpoint temperatures and cross-contamination risk reduction practices, in popular cookbook recipes. Design/methodology/approach Recipes containing raw animal ingredients in 29 popular cookbooks were evaluated through content analysis for messages related to safe endpoint temperature recommendations and reducing cross-contamination risks. Findings Of 1,749 recipes meeting study criteria of cooking raw animal ingredients, 1,497 contained a raw animal that could effectively be measured with a digital thermometer. Only 123 (8.2 percent) of these recipes included an endpoint temperature, of which 89 (72.3 percent) gave a correct temperature. Neutral and positive food safety behavior messages were provided in just 7.2 percent (n=126) and 5.1 percent (n=90) of recipes, respectively. When endpoint temperatures were not included, authors often provided subjective and risky recommendations. Research limitations/implications Further research is needed on the effect of these results on consumer behavior and to develop interventions for writing recipes with better food safety guidance. Practical implications Including correct food safety guidance in cookbooks may increase the potential of reducing the risk of foodborne illness. Originality/value Popular cookbooks are an underutilized avenue for communicating safe food handling practices and currently cookbook authors are risk amplifiers.

Pork is the most commonly consumed meat in Vietnam, and Salmonella enterica is a common contaminant. This study aimed to assess potential S. enterica cross-contamination between raw and cooked pork in Vietnamese households. Different scenarios for cross-contamination were constructed based on a household survey of pork handling practices (416 households). Overall, 71% of people used the same knife and cutting board for both raw and cooked pork; however, all washed their hands and utensils between handling raw and cooked pork. The different scenarios were experimentally tested. First, S. enterica was inoculated on raw pork and surfaces (hands, knives and cutting boards); next, water used for washing and pork were sampled to identify the presence and concentration of S. enterica during different scenarios of food preparation. Bootstrapping techniques were applied to simulate transfer rates of S. enterica cross-contamination. No cross-contamination to cooked pork was observed in the scenario of using the same hands with new cutting boards and knives. The probability of re-contamination in the scenarios involving re-using the cutting board after washing was significantly higher compared to the scenarios which used a new cutting board. Stochastic simulation found a high risk of cross-contamination from raw to cooked pork when the same hands, knives and cutting boards were used for handling raw and cooked pork (78%); when the same cutting board but a different knife was used, cross-contamination was still high (67%). Cross-contamination between was not seen when different cutting boards and knives were used for cutting raw and cooked pork. This study provided an insight into cross-contamination of S. enterica, given common food handling practices in Vietnamese households and can be used for risk assessment of pork consumption.

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.

ABSTRACT Salmonella and Campylobacter are among the most common causes of foodborne disease in the United States. Most illnesses are associated with eating raw or undercooked poultry or cross-contamination. Young children and older adults are more susceptible to contracting foodborne illness and have serious infections compared with other age groups. We conducted a Web-based survey of parents of young children (n = 1,957) and older adults (n = 1,980) to estimate adherence to recommended food safety practices for raw poultry and to identify differences in practices between the two groups. The findings present adherence rates for 20 practices. In both groups, less than 50% of respondents reported adherence to seven practices; thus, improvements are needed in these areas. Parent respondents were significantly more likely than older adult respondents to report following eight practices, with most related to avoiding cross-contamination and using a food thermometer. For example, parents (39%) were significantly more likely than older adults (31%) to report not rinsing or washing raw poultry (P &lt; 0.001). Older adult respondents were significantly more likely than parent respondents to report following seven practices, with most related to chilling to proper temperatures and thawing. For example, older adults (87%) were significantly more likely than parents (69%) to report cooking, freezing, or discarding raw poultry within 1 to 2 days of purchase as recommended (P &lt; 0.001). For the remaining five practices, no differences were found between groups. To motivate behavior change, food safety messages and materials must target specific at-risk populations as their practices are different. Additional research is needed to better understand how parents of young children and older adults like to receive food safety information and how to tailor the information to different generations.

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.
