The Muslim community has called on the city council to take action after a halal lamb burger made by a company supplying Leicester schools contained up to 50% pork.
The products were made by Doncaster-based Paragon Quality Foods Limited, which said it had never knowingly bought or handled pork.
Under Islamic law, Muslims are strictly forbidden to eat pork.
