Parents of students at a primary school in Chengdu City in southwestern China have been posting videos and photos of a moldy food canteen they say has led to diarrhea among the children. An investigation by local authorities found that one out of 19 batches of food samples had mold on its surface. And surveillance videos showed several people sneaking into the canteen, tearing up food wrappings and deliberately throwing them on the ground and then taking photos.
