Halal meat has been taken off the menu at 18 schools in Luton after concerns were raised by Muslim groups.
Luton Borough Council, which has served the meat in schools for 15 years, said it had suspended the service while it looked into how the meat was certified.
The decision followed a meeting with Luton Council of Mosques and Sunni Council of Mosques.
A council spokesperson said it did not relate to the "safety of the food or whether it has been contaminated".
Children at the schools affected by the decision, which was made at the end of April, are being served vegetarian meals while the checks are being made. [BBC] Read more
