Abstract
The climate crisis significantly impacts the health and well-being of older adults, both directly and indirectly. This issue is of growing concern in Canada due to the country's rapidly accelerating warming trend and expanding elderly population. This article serves a threefold purpose: (i) outlining the impacts of the climate crisis on older adults, (ii) providing a descriptive review of existing policies with a specific focus on the Canadian context, and (iii) promoting actionable recommendations. Our review reveals the application of current strategies, including early warning systems, enhanced infrastructure, sustainable urban planning, healthcare access, social support systems, and community engagement, in enhancing resilience and reducing health consequences among older adults. Within the Canadian context, we then emphasize the importance of establishing robust risk metrics and evaluation methods to prepare for and manage the impacts of the climate crisis efficiently. We underscore the value of vulnerability mapping, utilizing geographic information to identify regions where older adults are most at risk. This allows for targeted interventions and resource allocation. We recommend employing a root cause analysis approach to tailor risk response strategies, along with a focus on promoting awareness, readiness, physician training, and fostering collaboration and benchmarking. These suggestions aim to enhance disaster risk management for the well-being and resilience of older adults in the face of the climate crisis.

Berger N, Koch S, Jungnickel K, Böl GF. Food safety in the aging population: Qualitative findings on what to communicate and how. RISK ANALYSIS : AN OFFICIAL PUBLICATION OF THE SOCIETY FOR RISK ANALYSIS 2023; 43:1843-1854.

Abstract
The present study investigated older adults' risk perception, beliefs, and self-perception in the field of kitchen hygiene and food safety. A qualitative study with semi-structured focus groups was conducted. A total of 37 older adults (60-80 years of age) from Germany participated in four focus groups that were stratified by gender. Focus groups covered older adults' food-handling practices, their perceptions of vulnerability, and their informational needs in the field of food safety. A thematic analysis approach was adopted. The coding categories and subcategories were developed inductively by the researchers based on the data. The coded data were then used to identify overarching themes and subthemes. Main results showed that older adults had confidence in their knowledge and skills with regard to food safety, perceived their post-war generation overall to be resistant and other so-called at-risk groups to be more vulnerable. Moreover, they expressed low informational needs in the area of food safety. The results suggest that age-specific aspects play a role in older adults' risk perception and highlight the need to develop age-specific risk communication strategies that take into account older adults' beliefs, knowledge, and informational needs.

Abstract
Noncholera vibriosis is a rare, opportunistic bacterial infection caused by Vibrio spp. other than V. cholerae O1/O139 and diagnosed mainly during the hot summer months in patients after seaside activities. Detailed knowledge of circulating pathogenic strains and heterogeneities in infection outcomes and disease dynamics may help in patient management. We conducted a multicenter case-series study documenting Vibrio infections in 67 patients from 8 hospitals in the Bay of Biscay, France, over a 19-year period. Infections were mainly caused by V. alginolyticus (34%), V. parahaemolyticus (30%), non-O1/O139 V. cholerae (15%), and V. vulnificus (10%). Drug-susceptibility testing revealed intermediate and resistant strains to penicillins and first-generation cephalosporins. The acute infections (e.g., those involving digestive disorder, cellulitis, osteitis, pneumonia, and endocarditis) led to a life-threatening event (septic shock), amputation, or death in 36% of patients. Physicians may need to add vibriosis to their list of infections to assess in patients with associated risk factors.

Abstract
Seafood (fish in particular) is one of the main food groups in nutrition models with proven health benefits. Seafood has long been considered a very valuable dietary component, mainly due to presence of n-3 polyunsaturated fatty acids (n-3 PUFA) but it is also an important source of protein (including collagen), anserine, taurine, iodine, selenium, vitamin A, vitamin K, vitamin D, tocopherols, B vitamins and astaxanthin. Considering the beneficial effects of these ingredients on blood pressure, lipid profile and the inflammatory process, seafood should be an essential component of the diet. Non-communicable diseases (NCD) such as cardiovascular diseases, cancer, diabetes and mental disorder, chronic respiratory diseases are common diseases associated with advanced age. Promotion of a healthy lifestyle (including proper nutritional behavior) and prevention of diseases are the most effective and efficient ways to decrease premature mortality from NCD and to maintain mental health and well-being. This review article shows the potential preventive and therapeutic effects of seafood with an emphasis on fish. Our narrative review presents the results of systematic reviews and meta-analysis.

Abstract
BACKGROUND The early detection of enteric infections in older adults is challenging because typical signs and symptoms of disease may be less common, absent, or overlooked. Understanding illness characteristics of enteric infections among older adults could improve the timeliness and accuracy of clinical diagnoses, thereby improving patient outcomes and increasing cases reported to surveillance. METHODS Here, we describe illness characteristics (percentage reporting bloody diarrhea, fever, vomiting, abdominal pain; percentage hospitalized; duration of hospitalization; and duration of illness) among older adults (≥65 years) with acute gastroenteritis and culture-confirmed Campylobacter and nontyphoidal Salmonella infections in Australia, Canada, and the United States and compare these characteristics with those among younger people (<5 years, 5-24 years, and 25-64 years). RESULTS A significant negative correlation was found between all symptoms and increasing age group, except for bloody diarrhea in cases of acute gastroenteritis. Adults aged ≥85 years reported bloody diarrhea in only 9% of nontyphoidal Salmonella and 4% of Campylobacter infections compared with 59% and 55% among children aged <5 years. Conversely, a greater percentage of older adults (≥65) than younger persons (<5, 5-24, 25-64) reported being hospitalized, with an increasing linear relationship in age groups 65 years and older. CONCLUSIONS Although older adults are more likely to have severe illness and be hospitalized, we found that the proportion of persons reporting symptoms typically associated with enteric infections decreases with age. These findings have implications for clinical recognition and treatment of gastrointestinal illness, as well as for public health research.

Abstract
Unsafe food handling behaviors are common among consumers, and, given the venue, individuals attending a tailgating event may be at risk for foodborne illness. The objective of this study was to measure the association between Health Belief Model variables and self-reported usual food handling behaviors in a convenience sample of men and women at a tailgate event. Participants (n = 128) completed validated subscales for self-reported food handling behaviors (i.e., cross-contamination, sanitation), perceived threat of foodborne illness (i.e., perceived severity, perceived susceptibility), and safe food handling cues to action (i.e., media cues, educational cues). Perceived severity of foodborne illness was associated with safer behaviors related to sanitation (r = 0.40; P < 0.001) and cross-contamination (r = 0.33; P = 0.001). Perceived severity of foodborne illness was also associated with exposure to safe food handling media cues (r = 0.20; P = 0.027) but not with safe food handling educational cues. A large proportion of participants reported that they never or seldom (i) read newspaper or magazine articles about foodborne illness (65.6%); (ii) read brochures about safe ways to handle food (61.7%); (iii) see store displays that explain ways to handle food (51.6%); or (iv) read the "safe handling instructions" on packages of raw meat and poultry (46.9%). Perceived severity of foodborne illness was positively related to both dimensions of safe food handling as well as with safe food handling media cues. Except for the weak correlation between media cues and perceived severity, the relationships between safe food handling cues and perceived threat, as well as between safe food handling cues and behaviors, were nonsignificant. This finding may be due, in part, to the participants' overall low exposure to safe food handling cues. The overall results of this study reinforce the postulate that perceived severity of foodborne illness may influence food handling behaviors.

Abstract
OBJECTIVE To explore factors associated with self-reported food poisoning among Western Australian adults between 1998 and 2009. DESIGN Data were pooled from four Nutrition Monitoring Surveys Series which included information on suspected food poisoning among Western Australian adults. Descriptive statistics and multinomial regression analyses were used to describe factors associated with self-reported food poisoning, food safety knowledge and behaviours. SETTING Population of Western Australia estimated to be 2·5 million in 2009. SUBJECTS A representative sample of 4494 adults aged between 18 and 64 years. RESULTS There was no significant change in self-reported food poisoning over time, with about 18 % saying they had suspected food poisoning in the last 6 months. Overall, 2·1% said they had confirmed their food-borne illness with a nurse of doctor. People less than 34 years old, those with a university degree and people who ate meals out on the day prior to the survey (one meal: OR = 1·30, 95% CI 1·04, 1·62; two meals: OR = 2·21, 95% CI 1·30, 3·76) were the most likely to report food poisoning. Younger people were also more likely to have their food poisoning confirmed by a health professional. Use of refrigerator thermometers and cool bags for storing food increased significantly between 2004 and 2009. CONCLUSIONS Findings support the inclusion of food safety advice in dietary recommendations. Food safety and handling education and training is recommended for food businesses, particularly the takeaway food sector, and for consumers. Because food poisoning is reported more often by younger people, food safety education should begin during childhood.

Abstract
Bi-functional antibodies with the ability to bind two unrelated epitopes have remarkable potential in diagnostic and bio-sensing applications. In the present study, bispecific antibodies that recognize human red blood cell (RBC) and the food borne pathogen Listeria monocytogenes (L. monocytogenes) were engineered. The procedure involves initial reduction of a mixture of anti-RBC and anti-Listeria antibodies followed by gradual re-oxidation of the reduced disulphides. This facilitates association of the separated antibody chains and formation of hybrid immunoglobulins with affinity for the L. monocytogenes and human RBC. The bispecific antibodies caused the agglutination of the RBCs only in the presence of L. monocytogenes cells. The agglutination process necessitated the specific presence of L. monocytogenes and the red colored clumps formed were readily visible with naked eyes. The RBC agglutination assay described here provides a remarkably simple approach for the rapid and highly specific screening of various pathogens in their biological niches.

Abstract
OBJECTIVE To determine content, education channels, and motivational factors that influence what health professionals teach about safe food handling to populations who are highly susceptible for foodborne illnesses. To assess the differences in information provided by health professionals to highly susceptible populations. DESIGN Descriptive, cross-sectional, Web-based survey. SETTING National convenience sample from across the United States. PARTICIPANTS Registered nurses (RNs; n = 232) and registered dietitians (RDs; n = 267). MAIN OUTCOME MEASURE(S) Content, motivation, and education channels used to educate highly susceptible populations. ANALYSIS Various nonparametric tests were applied to measure differences. Significance was declared at P < .05. RESULTS Although both RDs and RNs were providing some food safety information to their high-risk clients, RDs had more training than RNs in safe food handling and were more likely to provide comprehensive food safety messages to their highly susceptible clients; however, neither professional type provided consistent food safety information to patients at high risk for foodborne illness. CONCLUSIONS AND IMPLICATIONS There is a need for more information about what motivates the health professional to teach safe food handling and a need for a universally adopted, evidence-based practice for teaching safe food handling to patients at high risk for foodborne illness.

Abstract
BACKGROUND Listeriosis can cause severe disease, especially in fetuses, neonates, older adults, and persons with certain immunocompromising and chronic conditions. We summarize US population-based surveillance data for invasive listeriosis from 2004 through 2009. METHODS We analyzed Foodborne Diseases Active Surveillance Network (FoodNet) data for patients with Listeria monocytogenes isolated from normally sterile sites. We describe the epidemiology of listeriosis, estimate overall and specific incidence rates, and compare pregnancy-associated and nonpregnancy-associated listeriosis by age and ethnicity. RESULTS A total of 762 listeriosis cases were identified during the 6-year reporting period, including 126 pregnancy-associated cases (17%), 234 nonpregnancy-associated cases(31%) in patients aged <65 years, and 400 nonpregnancy-associated cases (53%) in patients aged ≥ 65 years. Eighteen percent of all cases were fatal. Meningitis was diagnosed in 44% of neonates. For 2004-2009, the overall annual incidence of listeriosis varied from 0.25 to 0.32 cases per 100,000 population. Among Hispanic women, the crude incidence of pregnancy-associated listeriosis increased from 5.09 to 12.37 cases per 100,000 for the periods of 2004-2006 and 2007-2009, respectively; among non-Hispanic women, pregnancy-associated listeriosis increased from 1.74 to 2.80 cases per 100,000 for the same periods. Incidence rates of nonpregnancy-associated listeriosis in patients aged ≥ 65 years were 4-5 times greater than overall rates annually. CONCLUSIONS Overall listeriosis incidence did not change significantly from 2004 through 2009. Further targeted prevention is needed, including food safety education and messaging (eg, avoiding Mexican-style cheese during pregnancy). Effective prevention among pregnant women, especially Hispanics, and older adults would substantially affect overall rates.

Abstract
Listeria monocytogenes causes listeriosis, an uncommon but potentially fatal disease in immunocompromised persons, with a public health burden of approximately $2 billion annually. Those consumers most at risk are the highly susceptible populations otherwise known as the immunocompromised. Health professionals have a considerable amount of interaction with the immunocompromised and are therefore a valuable resource for providing appropriate safe food handling information. To determine how knowledgeable health professionals are about Listeria monocytogenes, a nationwide Web-based survey was distributed targeting registered nurses (RNs) and registered dietitians (RDs) who work with highly susceptible populations. Responses were received from 499 health professionals. Knowledge and understanding of Listeria monocytogenes was assessed descriptively. Parametric and nonparametric analyses were used to detect differences between RNs and RDs. The major finding is that there are gaps in knowledge and a self-declared lack of understanding by both groups, but especially RNs, about Listeria monocytogenes. RDs were more likely than RNs to provide information about specific foods and food storage behaviors to prevent a Listeria infection. Notably, neither group of health professionals consistently provided Listeria prevention messages to their immunocompromised patients. Pathogens will continue to emerge as food production, climate, water, and waste management systems change. Health professionals, represented by RNs and RDs, need resources and training to ensure that they are providing the most progressive information about various harmful pathogens; in this instance, Listeria monocytogenes.

Abstract
Elderly populations are vulnerable and generally have the highest incidence of morbidity related to foodborne illnesses and this problem may be aggravated in institutional or communal eating settings. The objective of this investigation was to examine the potential risk of food contamination in selected skilled nursing and assisted-living residences using bacteria indicator tests for Listeria spp., Salmonella spp. and E. coli. Of the 45 samples tested for Listeria, three (6.67 %) were found to be contaminated; Salmonella or E. coli contamination was not found in any of the samples. Reported incidents of foodborne illnesses are increasing in institutional settings, therefore there is an urgent need to collect information on practices that can prevent bacterial contamination of food served in elderly residences.

Abstract
OBJECTIVES Older adults are considered more vulnerable to foodborne illness due to lowered immune function. We compared the food safety perceptions and practices of older and younger adults and determined associations with demographic characteristics. METHODS We focused on 1,317 participants > or = 60 years of age from the U.S. Food and Drug Administration's 2006 Food Safety Survey, a telephone survey of a nationally representative sample of American consumers. We used data on participants < 60 years of age to compare younger and older adults, and used Pearson's Chi-square tests to determine whether perceptions and practices differed by age, gender, level of education, living arrangement, and race/ethnicity. We conducted multiple logistic regression analysis to assess relationship of demographic characteristics and food safety perceptions with food safety practices of older adults. RESULTS We found that adults > or = 60 years of age were more likely to follow recommended food safety practices than those < 60 years of age. Sixty-six percent of adults > or = 60 years of age reported eating potentially hazardous foods in the past year compared with 81% of adults < 60 years of age. Among people > or = 60 years of age, women, those with less education, and nonwhite individuals generally had better food safety practices and a greater awareness of food safety risk. CONCLUSIONS These findings suggest that certain subsets of the older adult population are less likely to follow recommended food safety practices and, thus, are at greater risk of foodborne illness. Food safety education for older adults should target men and those with more education and higher incomes.

Abstract
Given the federal cost-containment policy to rebalance long-term care away from nursing homes to home- and community-based services, it is the position of the American Dietetic Association, the American Society for Nutrition, and the Society for Nutrition Education that all older adults should have access to food and nutrition programs that ensure the availability of safe, adequate food to promote optimal nutritional status. Appropriate food and nutrition programs include adequately funded food assistance and meal programs, nutrition education, screening, assessment, counseling, therapy, monitoring, evaluation, and outcomes documentation to ensure more healthful aging. The growing number of older adults, the health care focus on prevention, and the global economic situation accentuate the fundamental need for these programs. Yet far too often food and nutrition programs are disregarded or taken for granted. Growing older generally increases nutritional risk. Illnesses and chronic diseases; physical, cognitive, and social challenges; racial, ethnic, and linguistic differences; and low socioeconomic status can further complicate a situation. The beneficial effects of nutrition for health promotion, risk reduction, and disease management need emphasis. Although many older adults are enjoying longer and more healthful lives in their own homes, others, especially those with health disparities and poor nutritional status, would benefit from greater access to food and nutrition programs and services. Food and nutrition practitioners can play a major role in promoting universal access and integrating food and nutrition programs and nutrition services into home- and community-based services.

Abstract
OBJECTIVE to explore midwives' perceptions of food-related risks and their approaches to Listeria education during pregnancy. DESIGN an exploratory design within a qualitative framework. SETTING one private and two public hospitals in New South Wales, Australia. PARTICIPANTS 10 midwives providing antenatal care in the selected hospitals. FINDINGS midwives had a range of approaches, from active to passive, to Listeria education. The main education provided was focused only on some of the high Listeria-risk foods with little education on safe food-handling practices. Midwives' perception of food-related risks was a function of their limited scientific knowledge and their reliance on their experiential knowledge and their common sense. System constraints such as temporal pressure, limited availability of educational materials and low adherence to Listeria recommendations within the health system were also identified to influence midwives' practice. KEY CONCLUSIONS professional practice guidelines regarding food safety and Listeria education are needed, together with relevant professional training and review of hospital practices in relation to this important health issue.

Abstract
We describe recent epidemiological changes in salmonellosis. Linking 1968-2000 National Salmonella Surveillance System to census data, we calculated population-based age- and sex-stratified rates of non-urinary salmonellosis for the top 30 non-typhoidal serotypes. Using 1996-1997, 1998-1999, and 2000-2001 population-based FoodNet surveys, we compared reported diarrhoea, medical visits, and stool cultures. Despite an overall female-to-male incidence rate ratio (FMRR) of 0.99, the sex-specific burden of salmonellosis varied by age (<5 years FMRR 0.92; 5-19 years 0.85; 20-39 years 1.09; 40-59 years 1.23, and 60 years 1.08) and serotype (FMRR range 0.87 for Mississippi to 1.25 for Senftenberg). Serotype-specific FMRRs and median age (range 2 years for Derby to 29 years for Senftenberg) were related (correlation 0.76, P<0.0001). Recently, the relative burden of salmonellosis in women has increased. FoodNet data suggest that this change is real rather than due to differential reporting. Excess salmonellosis in women may reflect differences in exposure or biological susceptibility.

Abstract
This study examined the effects of an educational intervention on improving home food safety practices (HFSP) in 136 older adults (mean age: 79 years; 74% female; 61% Caucasian). At the pre-test, adherence to 16 HFSP was variable and ranged from <or= 17% for checking temperatures of the refrigerator and cooked meats to >or= 76% for other practices. Following the intervention, participants were more likely to wash their hands with warm water and soap for 20 seconds before eating (76% vs. 90%, P <or= 0.01) and preparing food (76% vs. 92%, P <or= 0.01). In a series of regression analyses, younger age was the most consistent predictor of adherence to HFSP at the pre-test, and older age was the most consistent predictor of improvements in adherence after the intervention. This intervention improved several aspects of HFSP; however, additional interventions are needed to increase HFSP in older adults.
