Thousands of children are at risk of food poisoning from dirty school canteens where inspectors have found mouse droppings, filthy plates and staff who handle the food without washing their hands.
At least 60,000 children attend schools with dangerous food hygiene levels, according to analysis of data from the Food Standards Agency.
It shows that 207 schools and nurseries need to improve their food safety standards to comply with the law.
This means the schools were given zero, one or two stars out of five by inspectors in England, Wales and Northern Ireland or “improvement required” in Scotland.
