The purpose of this study was to determine the causes of food waste at the lowest level, i.e. in the household, and to determine the most effective information channels for educational campaigns that provide consumers with ways to minimise this phenomenon. The study was based on a survey questionnaire developed by the authors and administered to a total of 1384 respondents. The statistical analysis, including descriptive statistics and the ANOVA test, was performed with the use of Statistica 13.3 PL. Also used were linear regression statistics. The study provided a basis for the conclusion that Generation Z consumers, who participated in the study, perceive the information contained on the label as relevant and important at the time of purchase. Specifically, consumers checked the product's ingredients, expiration date and price. As the main reason for food waste in households, consumers indicated that they do not track the expiration dates of purchased products when found again in the kitchen, and are already past their best-before date. The respondents identified as the key information and educational channels that contribute to raising consumer awareness: web pages run by institutions, bloggers/influencers, experts, social media, and, as the least important one, TV programs.
