Analysis of changes in shopping habits and causes of food waste among consumers before and during the COVID-19 pandemic in Poland

ABSTRACT

Food waste is a worldwide phenomenon that needs to be reduced. The causes of this problem vary widely. The study used the Computer-Assisted Web Interview method. There were 500 respondents from all over the country and among them 60% women and 40% men. The sample selection was purposeful. Before the pandemic began, the highest percentage of consumers shopped two to three times a week. As of March 2020, the frequency of this activity has decreased for every fourth respondent. Also during this period, an increase in the frequency of shopping alone was observed, as well as an increase in the number of people who outsource their shopping list to others. Nowadays, the vast majority of respondents usually create a shopping list before doing it and follow it. Before the pandemic, this was the case for only 46% of respondents, while during the pandemic it was the case for 81%. Exceeding the expiration date was the most common reason for throwing products in the trash before as well as during the pandemic. Over-shopping as a cause of food waste increased almost fourfold during the pandemic. A positive aspect is noticeable for the 'I don't throw food away' response. The percentage of respondents increased from 16% to 21%. During both survey periods, respondents most often indicated that they throw away fruits, vegetables, bread, and dairy products. During the COVID-19 pandemic, consumers' shopping behaviour changed. They attended grocery stores far less frequently, mostly on their own, and purchased larger quantities of products. Nonetheless, consumers planned their purchases and checked expiration dates before putting food in their shopping carts. Households were thus forced to respond quickly, adjusting their shopping behaviour. These behaviours have implications for the subsequent activities of retail merchants.
