Authorities have called for nationwide enforcement of food standards in schools amid an ongoing investigation into a Shanghai-based food supplier accused of serving low-quality lunches with expired ingredients at a private school in the city.

The Shanghai Municipal Food and Drug Administration confirmed in a statement on Tuesday that students at the SMIC Private School in the Zhangjiang Hi-Tech Park were served expired food, including rotten and moldy produce. Expiration dates on the packaging of some products had been altered. The investigation confirmed what the students’ parents reported during a surprise inspection of the school’s kitchen on Friday.

The State Administration for Market Regulation and the Ministry of Education urged local education and food authorities on Tuesday to strengthen inspections of campus canteens to ensure their safety. On Saturday, SMIC Private School apologized to students, staff and parents and promised to take full responsibility for failing to supervise the vendor, according to its website. The principal of the school has been dismissed.
