A joint campaign by multiple Chinese government departments to investigate and rectify campus food safety has led to the filing of 10,200 illegal cases and the suspension of 85 companies. The campaign, which started in December 2023, has also revoked six licenses and banned 14 companies from operating without a license. Additionally, measures such as equipment maintenance, guidelines for pest control, and increased supervision have been implemented to prevent rats in school canteens. Critics suggest that the complexity of school canteens and the pursuit of profit maximization by enterprises operating them contribute to campus food safety issues.
