Recent studies have reported that climate change is affecting the occurrence of food poisoning. However, research on the impact of heat waves, a representative extreme weather event, on the occurrence of mass food poisoning is still lacking. Therefore, to fill the research gap, this study estimates the effects of heat waves on the incidence of mass food poisoning cases using yearly administrative panel data from 2002 through 2020. Using an instrumental variable approach, we find that an extra day of heat waves would increase the incidence of mass food poisoning cases by approximately 7.4%, resulting in social and economic costs of 137.1 billion won per year. It implies that precautionary measures to adapt to heat waves are needed.
