The Impact of Social Disruption on Food Safety: Evidence from COVID-19 and Vegetable Pesticide Residue

Huang, Kaixing and Liu, Pengfei and Liao, Yuxi and Wang, Zhengcong (2024): The Impact of Social Disruption on Food Safety: Evidence from COVID-19 and Vegetable Pesticide Residue.

Abstract

Vegetable pesticide residues are a pervasive food safety concern. Utilizing over half a million records of vegetable tests from 287 cities, we find that COVID-19 increases the national average pesticide residue by 11% during the peak months of the pandemic in China. The pandemic nearly doubled the pesticide testing failure rate in cities with the highest infection rates. Empirical evidence suggests that the estimated effect stems from pandemic-induced disruptions in vegetable production and transportation, which result in untimely pest control and subsequent overuse of pesticides. Pandemic-related vegetable pesticide residue changes increase health risks by up to 10% in cities with the highest COVID-19 infection rates. Our findings underscore the significant impact of social disruptions on food safety through a channel largely overlooked in the literature.
