However, the gender and social dimensions of food safety are often overlooked and undervalued. Women, who are primary caretakers in households, play a vital role in food preparation, storage, and consumption. Gender inequality can result in limited access to resources and information needed for safe food handling and storage, increasing women's vulnerability to foodborne illnesses. Cultural practices, education, and income levels also impact food safety. These factors can contribute to disparities in food safety and increase the risk of foodborne illnesses among certain populations. Promoting gender equality, cultural sensitivity, and addressing income inequality are essential to ensure safe and secure food for all. Addressing these issues can lead to a more equitable and sustainable food system.</p>","PeriodicalId":93795,"journal":{"name":"JSFA reports","volume":"4 7","pages":"280-285"},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jsf2.211","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141679038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
