The Contrast Pressures on Consumer-Level Food Waste During a Pandemic: The Impact of Infection Salience Versus Lockdown Salience
Have you ever wondered why some people threw away more food during the COVID-19 pandemic, while others became more cautious about waste? This matters because food waste significantly impacts climate change, inflates food prices, and worsens global hunger. This research, authored by Huachao Gao and forthcoming in the Journal of Consumer Research, provides clear answers and actionable solutions to this important puzzle.
Two Faces of Pandemics: Infection vs. Lockdown
This research finds that pandemics influence consumer food waste through two main psychological pathways: infection salience and lockdown salience. When people primarily think about the infectious nature of a disease, they become highly concerned about food safety. Their fears about leftover contamination increase significantly, prompting them to discard more food, especially leftovers. During COVID-19, exaggerated concerns led many people to discard edible food, despite official guidelines confirming its safety. These heightened safety fears led to a notable increase in consumer food waste.
On the other hand, when attention shifts towards lockdown measures and the accompanying resource scarcity, consumers become more cautious and resource-conscious. Issues like grocery shortages, financial uncertainties, job losses, and restricted access to fresh foods drive people to better manage and conserve their food. As a result, they substantially reduce their food waste. This dual psychological effect clearly explains why media and research reports about food waste during COVID-19 appeared conflicting.
Intervention Strategies
Given that many infectious diseases amplify safety concerns without necessarily causing lockdowns, it is critical to find effective strategies to curb food waste during periods of heightened infection awareness. This research introduces a practical “safety-health intervention” specifically designed to reassure consumers about the safety and healthiness of consuming leftovers. The intervention was tested in multiple real-world contexts, proving effective across various applications:
- Restaurant table tents emphasized that provided to-go boxes offer a safe and healthy method for storing and later consuming leftovers.
- Napkins printed with reassuring messages like “Safe & Healthy Way of Eating & Packing” effectively prompted diners to reconsider throwing away perfectly edible food.
- To-go boxes clearly labeled with safety messages (“Safe and Healthy”) significantly increased the likelihood that consumers would pack and later consume their leftovers compared to traditional sustainability-focused messaging (“Green and Easy”).
These interventions were straightforward, cost-effective, and easily implementable, demonstrating substantial real-world effectiveness in reducing food waste.
Why Does This Matter?
Reducing food waste is critical for policymakers, businesses, and individual consumers. Internationally, the United Nations and governments like the U.S. strongly emphasize food waste reduction as vital for achieving sustainability goals, addressing climate change, and alleviating global hunger. Policymakers can leverage this research to create targeted campaigns highlighting food safety, especially during health crises.
Businesses, especially restaurants and food retailers, benefit significantly by adopting these insights to improve customer trust, satisfaction, and loyalty through socially responsible and relevant messaging. For individual consumers, understanding the psychological drivers behind their food waste behaviors helps improve their resource management skills, leading to increased financial savings and better psychological well-being.
Overall, this research provides valuable insights into the distinct ways pandemics affect consumer behavior regarding food waste and offers practical, actionable strategies for addressing this critical issue. Adopting these solutions will meaningfully contribute to environmental sustainability, economic efficiency, and enhanced individual and community well-being.
