Maybe you’ve never been a fan of cafeteria food. Maybe for you, lunch was the time you dreaded the most. But however bad your school lunches were, they likely weren’t accused of being made with pig feed and rotten food like one Shandong school.

About a hundred parents descended on the Haiyang Yingcai Experimental School in Yantai on Monday to protest the school’s alleged use of pig and chicken feed to prepare meals for its schools.

The scandal spread when photographs shared online showed the cafeteria’s unpalatable food being prepared. One showed an opened bag of chicken feed with a chicken outline stenciled on the bag.

The school explained that nothing is wrong with its food. Eggs suspected of being rotten by the parents were explained to be “tea eggs”, while the opened bags of chicken feed were explained away as not being used as part of the students’ lunches.

While a government investigation is pending, the photos of the food suggest that it is may not be suitable for humans or animals.
