More than 200 children are being treated in hospital with lead poisoning in north-west China, after school chefs used inedible paint to decorate their food.
Eight people have been arrested after tests showed the food samples from a kindergarten had lead levels that were 2,000 times over the national safety limit.
BBC News reported 233 children fell ill after eating steamed red date cake and sausage corn bun, with lead levels of 1052mg/kg and 1340mg/kg respectively, both exceeding the national food safety standard limit of 0.5mg/kg.
Chinese state media aired footage which it said was from CCTV cameras in the kitchen which showed staff adding paint pigment to the food.
