Consumers' practices and safety perceptions regarding the use of materials for food preparation and storage: Analyses by age group.

Abstract

Food Contact Materials (FCM) are those intended to be in contact with food, during its production, handling, and storage. FCM contain chemicals that could migrate to the foodstuff, posing potential health concerns, and usage practices influence the level of migration. This study assesses the preferences, safety perceptions, and usage practices of Portuguese consumers regarding FCM used for cooking and food storage (cookware). An observational, quantitative, and transversal study was performed through an online survey created for this purpose, which involved 1179 Portuguese adults. Results were analyzed according to age. Safety was the factor considered most important when choosing cookware materials, although the choice criteria varied with age. The majority of respondents recognize the risk of food contamination through cookware. Stainless steel and glass were considered the safest materials for cooking. The materials most used to reserve food are glass and plastic. Older individuals carry out more maintenance of cookware and have greater knowledge about how to wash and store it. Regarding the FCM symbology, there is a general lack of knowledge. Our study demonstrates the need to disseminate reliable information to the general public about cookware, contributing to greater literacy in health and to less exposure to food contact chemicals.
