Abstract
Food safety is a global health issue, leading to foodborne illnesses and economic burdens worldwide. Ensuring high food safety standards is challenging because of the variations in knowledge, attitudes, and practices (KAP) among consumers and vendors. This umbrella review synthesizes reviews on consumer and vendor food safety KAP research from the last 20 years. Therefore, a comprehensive Web of Science, Scopus, and Google Scholar search was conducted. The eligibility of the review studies was assessed using the Population, Concept, and Context (PCC) framework, targeting systematic, scoping, and integrative reviews that examined one or more KAP components related to food safety. The quality assessment was accomplished using the ROBIS tool, with findings synthesized narratively. The review incorporates 20 review studies, covering 839 primary articles on food safety KAP across diverse contexts and regions. The quality assessment revealed a low risk of bias in most studies. Findings show that consumers are generally more knowledgeable and better adherent to food safety guidelines, driven by personal health motivations. However, vendors often exhibit inconsistent practices due to limited education and resources. Both groups exhibit positive attitudes but fail to apply safe practices consistently. The inadequacy of food safety KAP highlights the influence of regional, cultural, economic, and socio-demographic factors on practices. Future research should focus on underrepresented regions, improve methodologies, and explore vendor-consumer relationships. Emphasizing longitudinal studies, qualitative research and crossregional comparisons will enhance understanding of food safety KAP. Key recommendations include continuous training, community awareness, policy improvements, enhanced enforcement, increased investment in education, and public-private partnerships to strengthen food safety standards and safeguard public health.
