Food safety and older people: the Kitchen Life study.

Indigenous populations are often at higher risk for foodborne illness than the general Canadian population. To investigate the extent of the literature on the link between food safety and the occurrence of foodborne and waterborne illness in Canadian Indigenous populations. A scoping review was conducted using search strings in five databases and grey literature to identify all papers that studied a Canadian Indigenous population and referred to any potential associations between food safety (including consumption and preparation of traditional foods and retail foods) or water safety practices and food or waterborne illness. Two authors screened papers based on inclusion and exclusion criteria. Included documents were analyzed for emergent themes. From 1,718 unique records identified, 21 documents were selected. Foodborne illness was most common in children up to 14 years old. Walrus, seal, caribou and whale were the most common traditional foods tied to foodborne illness and were primarily associated with botulism and trichinosis. Aside from consuming the food raw, fermentation was the most common traditional preparation method linked to foodborne illness. There was concern about the safety of retail food but no clear link was identified with foodborne illness. Lastly, although there was concern about tap water, the use of alternate water sources, such as untreated brook water, and hygiene and cleaning practices in communities with boil water advisories were the most common risk behaviours associated with waterborne illness. Consumption of certain game meats, as well as the use of traditional fermentation practices may lead to an increased risk of foodborne illness among Indigenous populations. Concern about tap water may lead to use of unsafe alternate water sources. Further research is needed to examine potential culturally appropriate food and water safety opportunities.

Young, older, pregnant, and immunocompromised (YOPI) people are most vulnerable to foodborne illnesses due to impaired or underdeveloped immune systems(1). There is a lack of information regarding how YOPI groups access, receive or use information about food safety, what influences their food safety behaviour, and their preferences for receiving food safety advice. The objective of this research was to develop a better understanding of how YOPI consumers in New Zealand access and use food safety information, the types and sources of food safety information used, how information and advice are obtained, and how these influence their decision-making about food safety practices and related behaviours. Research questions were guided by a rapid review of literature. Twenty qualitative focus groups (comprising of either young, old, pregnant, or immunocompromised individuals) based in one of three locations in New Zealand were conducted. This was complemented with data from health care providers from relevant sectors (nutritionists, dietitians, aged care providers, cancer nurses, Well Child Tamariki Ora providers, and midwives). Recruitment included a focus on ethnic groups (Māori and Pasifika) to ensure diversity of experiences and perspectives were represented in the research and to reflect NZFS’s interest in developing fit-for-purpose messages and resources for these YOPI populations. Thematic and segmentation analysis was conducted to understand current food safety behaviours and how to best communicate food safety matters. Typologies of participants were developed by grouping participants based on common features: attitudes, beliefs, and experiences. The research revealed most participants are comfortable with their food safety practices and reported habitual behaviours. Many YOPI did not perceive themselves to be at a greater risk of foodborne illness, particularly older people. A key finding was that access to information does not necessarily lead to behaviour change. Groups undergoing periods of change (immunocompromised, pregnant and young) were more likely to seek additional information. Families and health professionals are trusted sources of information, with all groups reporting some use of the internet as an information source. An individual’s risk perception was the main motivating factor for obtaining and following advice. Habit, cost of food, and lack of information were key barriers to obtaining or acting on information, along with pregnant people reporting social pressures as a reason to not obtain or act on relevant advice. In general, there are three key types of food-safety messaging all groups would like to receive: situation-specific advice; information received alongside other key information (e.g., starting solids); and general information for the whole population. Gaining insights into YOPI preferences on food safety matters can aid the development of appropriate communication and engagement methods of the risks and impacts of food safety matters to vulnerable people.

In Maryland, county Food Protection Programs (FPP), housed within Environmental Public Health (EPH) Divisions, maintain responsibility for regular inspection of all food service facilities (FSF). With growing concerns about how our food supply is protected, it is important to determine the state and effectiveness of our food safety systems. This research elucidates the roles, responsibilities, strengths, and weaknesses of Food Safety and Protection Programs in Maryland. A 16-question survey tool, which addressed facets of the local food protection infrastructure, including FSF inspections, staffing, budget, and foodborne illness surveillance, was distributed to all 24 county FPP. The number of FSF in Maryland increased 97% from 2001 to 2006 and counties had an average inspection completion rate of 73%, with a 4% increase over the time period. Statewide, there were 4.1 EPH full-time employees (FTE) per 10 000 population and 1.6 FPP FTE per 10 000 population. EPH Division budgets increased 63% statewide, from $19.5 million in 2000 to $31.9 million in 2007. FPP budgets also increased 59% over the period, from $6.2 million in 2000 to $9.8 million in 2007. This study offers new quantitative measures of the demands, capacities, and performance of Food Protection and Safety Programs in Maryland. This assessment of local EPH and FPP capacity also offers insight into the strengths and weaknesses of the local food protection and safety infrastructure. Importantly, it reveals an infrastructure and dedicated food protection workforce that inspects the food supply and responds to foodborne illness outbreaks. Yet, resources vary substantially from county to county, impacting which services can be provided and how well they can be performed. This can, in turn, impact the potential risk of foodborne illness and the public's overall health.

Preventive Strategy Against Infectious Diarrhea—A Holistic Approach

Ensuring a safe and adequate food supply is a cornerstone of human health and food security. However, a significant portion of the food produced for human consumption is wasted annually on a global scale. Reducing harvest and postharvest food waste, waste during food processing, as well as food waste at the consumer level, have been key objectives of improving and maintaining sustainability. These issues can range from damage during processing, handling, and transport, to the use of inappropriate or outdated systems, and storage and packaging-related issues. Microbial growth and (cross)contamination during harvest, processing, and packaging, which causes spoilage and safety issues in both fresh and packaged foods, is an overarching issue contributing to food waste. Microbial causes of food spoilage are typically bacterial or fungal in nature and can impact fresh, processed, and packaged foods. Moreover, spoilage can be influenced by the intrinsic factors of the food (water activity, pH), initial load of the microorganism and its interaction with the surrounding microflora, and external factors such as temperature abuse and food acidity, among others. Considering this multifaceted nature of the food system and the factors driving microbial spoilage, there is an immediate need for the use of novel approaches to predict and potentially prevent the occurrence of such spoilage to minimize food waste at the harvest, post-harvest, processing, and consumer levels. Quantitative microbial spoilage risk assessment (QMSRA) is a predictive framework that analyzes information on microbial behavior under the various conditions encountered within the food ecosystem, while employing a probabilistic approach to account for uncertainty and variability. Widespread adoption of the QMSRA approach could help in predicting and preventing the occurrence of spoilage along the food chain. Alternatively, the use of advanced packaging technologies would serve as a direct prevention strategy, potentially minimizing (cross)contamination and assuring the safe handling of foods, in order to reduce food waste at the post-harvest and retail stages. Finally, increasing transparency and consumer knowledge regarding food date labels, which typically are indicators of food quality rather than food safety, could also contribute to reduced food waste at the consumer level. The objective of this review is to highlight the impact of microbial spoilage and (cross)contamination events on food loss and waste. The review also discusses some novel methods to mitigate food spoilage and food loss and waste, and ensure the quality and safety of our food supply.

SummaryFood safety, whether actual or perceived, is one of the major reasons for food waste along the agri‐food supply chain. Food safety hazards at farm level such as mycotoxin contamination of feed, overuse of antimicrobials in livestock disease control, and zoonotic disease incursion may lead to food unfit for human consumption and thus waste. Given the importance of safety as one of the most important attributes of food, the appropriate management of risks along the supply chain can contribute to reductions in food loss and waste. However, a better coordination between food waste and safety policies is also needed, which requires: balancing the scientific evidence and the precautionary principle; reviewing current food safety regulations to identify areas potentially leading to avoidable waste; combining the monitoring of safety hazards and waste along the agri‐food chain; provision of tailored information on linkages between food safety and waste; and investment in technologies to accurately assess the edibility of food. Attention needs to be paid to policies and practices on food labelling and packaging to ensure that they do not lead to unintended or unnecessary impacts on food safety and waste, which are not justified by scientific evidence.

Cutting edge technologies to end food waste

Older adults are at greater risk for foodborne illness due to age and weakened immune function. Despite higher susceptibility to foodborne illness, older adults have low knowledge of food safety risk. It is essential to identify unsafe food handling behaviors among older adults so that interventions can be developed to decrease the likelihood of foodborne illness. Targeted, needs‐driven education materials and programs are the best methods to increase risk awareness among older adults and to provide the necessary prevention steps. The study purpose was to assess food handling behaviors that are increasing community‐residing older adults’ risk for foodborne illness. A convenience sample of 720 older adults from 67 congregate meal sites in a Midwest state completed a 10‐item food safety knowledge questionnaire that asked about the frequency of performing food safety behaviors. Participants were primarily widowed (54.3%), white (95.9%), females (75.4%), with a mean age of 78.6 years, who had a high school education (46.6%), and reported being in “average” health (31.9%). Review of descriptive statistics identified safety practices; chi‐square tests evaluated the associations between frequency of food safety practices, age, and gender. The majority of participants reported regularly practicing these specific safe food handling practices: refrigerating cold food immediately (97.6%), washing cutting boards after contact with meats (93.6%), discarding suspicious leftovers (93.6%), keeping sponges and towels clean (92.3%), and washing hands before food prep (91.4%). Conversely, a number of safety behaviors were not observed including: (1) thaw meat in refrigerator (50.0%), (2) pick up refrigerated/ frozen food just before checking out (38.5%), (3) check “sell‐by” and “use by” dates on packages (35.8%), or (4) use separate cutting boards for meat (21.0%). Age category was associated with picking up refrigerated / frozen food just before checking out (χ2[3] = 8.45, p = .038) and refrigerating leftovers immediately (χ2 [3] = 8.18, p = .043); participants aged 71–80 years reported a higher frequency of responding “no” than other age groups. Gender was associated with washing cutting boards after contact with meat (χ2 [1] = 12.25, p < .001) and keeping towels and sponges clean (χ2 [1] = 9.86, p = .002); a higher percentage of males reported “no” to these behaviors. Future food safety education for older adults should target these aforementioned food safety practices to reduce the risk of foodborne illness. Specific education should be targeted to older adults age 71–80 related to refrigeration safety and to older males regarding cleaning of food prep materials.Support or Funding InformationFunded by USDA's SNAP, an equal opportunity provider and employer, in collaboration with the Iowa Department of Public Health
