Compliance With Recommended Food Safety Practices in Television Cooking Shows

Exploring Food Safety Messages in an Era of COVID-19: Analysis of YouTube Video Content

ABSTRACT

Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not a proven foodborne pathogen, the COVID-19 pandemic has put the food system on alert, and food safety has been identified as an important pillar in mitigating the crisis. Therefore, an understanding of how popular media are used as a vital disseminator of food safety and health information for the public is more important than ever. YouTube deserves particular attention as one of the most highly trafficked Web sites on the Internet, especially because YouTube has been blamed during the pandemic for spreading misleading or untrustworthy information that contradicts validated information. This study was conducted to evaluate the food safety information and practices circulating on YouTube during the COVID-19 pandemic and the alignment of these practices with recommendations from government agencies. A search for videos on YouTube was conducted using the key words "food and COVID-19," "food safety and COVID-19," and "groceries and COVID-19." After applying a series of inclusive and exclusive criteria, 85 videos from the United States and Canada were evaluated. More than half (69%) of the videos presented hand washing procedures, 26% showed kitchen disinfection, and most (86%) showed take-out food or grocery store practices. Multiple produce washing procedures were also shown throughout videos. Food was not considered hazardous in 39% of the videos, but 24% mentioned that food packaging is potentially hazardous. Most videos cited government agencies and had a host or guest who was a health care professional, professor, or expert. Three videos were not aligned with a government agency's guideline or information cited; two were presented by a health care professional. These findings reveal the need to develop educational interventions that increase YouTube video host and guest awareness of social media use as a tool for food safety dissemination and the need to provide trustworthy information.

"My Roommates Would Laugh at me": Young Males Reveal Embarrassment over Lack of Food Skills

Purpose: This descriptive qualitative study explored young males' perceptions of food skills in 3 domains: food selection and planning, food preparation, and food safety and storage.Methods: Semi-structured interviews were audio-recorded and transcribed verbatim. Data were analyzed using the constant comparative method.Results: Forty-four young men (aged 17-35) reported varying levels of food skills, from little/no confidence to very confident and skilled. Most participants learned food skills from their mothers. Greater involvement in food selection and planning at a young age appeared to be related to parental influence and encouragement, exposure to food skills at school, and interest in food-related activities, which, in turn, provided a solid foundation for being confident cooks as young adults. Most notable was the lack of knowledge about, or confidence in, food safety and storage. Young men with low self-perceived food skills were deeply embarrassed about this deficiency in front of peers who had higher levels of confidence and skills.Conclusions: Future interventions or curricula should emphasize food safety and storage. This research also illustrates the importance of the home environment in teaching food skills to youth and ensuring that food skills are taught well before young adults begin living independently.

Kitchen Hygiene in the Spotlight: How Cooking Shows Influence Viewers' Hygiene Practices

Poor hygiene when handling food is a major cause of foodborne illness. To investigate whether hygiene practices visible in television cooking shows influence viewers' kitchen hygiene, a study on the adoption of demonstrated hygiene behavior was conducted under controlled, experimental conditions. In a study ostensibly on cooking by following recipes participants (n = 65) were randomly assigned to one of three conditions, in which they watched a cooking video that differed only with regard to the hygiene behavior of the chef. In condition 1, the chef engaged in poor hygiene practices while preparing the dish, in condition 2 the chef's hygiene behavior was exemplary and in condition 3, the chef's hygiene behavior was not visible (control condition). After watching the video, participants were instructed to cook the recipe individually in the fully equipped laboratory kitchen. Cooking sessions were videotaped and experimenters blind to condition coded hygiene lapses committed by participants. The level of kitchen hygiene displayed in the cooking video significantly affected hygiene practices of participants cooking the recipe. Participants who had watched the cooking video with correct hygiene practices committed significantly fewer hygiene lapses than those who had watched the video with poor hygiene practices. From a risk communication perspective, TV cooking shows are well placed to convey knowledge of essential hygiene practices during food preparation to a broad audience. To facilitate behavioral change toward safer food-handling practices among viewers, visibly performing correct hygiene practices in cooking shows is a promising strategy.

Growth and Survival of Foodborne Pathogens during Soaking and Drying of Almond (Prunus dulcis) Kernels

ABSTRACT

The practice of soaking almonds prior to consumption is popular both commercially and at home. The food safety implications of soaking almonds was investigated through analysis of blogs and videos (n = 85 recipes) to identify both the reasons for soaking almonds and the common practices employed. Among the recipes analyzed, the most common reasons for soaking almonds (94.1%) were perceived benefits such as improved digestion and nutrient uptake. Most recipes (34.1%) suggested soaking at "room temperature" for times that ranged from 4 to 24 h or, more commonly, "overnight" (51.8%). Postsoaking drying instructions were provided in 40 recipes (47.1%). Among those providing a drying temperature (31.8%), 85% specified 66°C and lower. To evaluate the growth of foodborne pathogens during almond soaking, separate cocktails of Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella enterica were inoculated onto raw almonds or into the soak water (almonds-to-water ratios of 1:1 and 1:3 [w/v]). Populations were monitored during soaking at 15, 18, and 23°C for up to 24 h, and during postsoak drying at 66°C for 14 h (for Salmonella only). At 15°C and a 1:1 almond:water ratio, no significant population increase (P > 0.05) was observed between 0 and 24 h for any of the pathogens. At 18°C, increases of 0.63, 1.70, and 0.88 log CFU per sample were observed over 24 h for populations of E. coli O157:H7, L. monocytogenes, and Salmonella, respectively. Populations of E. coli O157:H7, L. monocytogenes, and Salmonella increased by 3.48, 3.22, and 3.94 log CFU per sample, respectively, after 24 h at 23°C. When soaked almonds were dried for 14 h at 66°C, moisture and water activity decreased from 40 to ∼6% and 0.99 to 0.60, respectively, but no significant reduction in Salmonella populations was observed. Recommendations for using shorter times (<8 h) and cooler temperatures (≤15°C) should reduce the potential for foodborne pathogens, if present, to grow during soaking of almonds.
