Almost 300 schools in west Wales are being told to return food intended for school dinners after rats were found in a supplier's warehouse.
The council said Skelfayre had put in place a product recall
Pembrokeshire Council said rats were found during a routine inspection at the Skelfayre warehouse, Pembroke Dock.
The warehouse supplies food for school meals in Pembrokeshire and neighbouring Carmarthenshire and Ceredigion.
Pembrokeshire council said contaminated food will be destroyed and described it as an isolated incident.
The warehouse was closed on Tuesday after being visited by officers from Pembrokeshire Council.
The council said it found "rat infestation with evidence of product damage and contamination".
The company supplies between 400 and 500 catering businesses each week, including schools, residential care homes, hotels, and restaurants across three counties in mid and west Wales.
The leader of Pembrokeshire County Council, John Davies said: "There is no danger, and the proper procedure has been followed with regards to this kind of incident.
"I'm sure with the total co-operation with the company, as we have experienced, normal service will be resumed as soon as it effectively possible."
The council added that a food product recall has been put in place by Skelfayre, covering food supplied before 5 July.
Council officers are contacting businesses to confirm that they are aware of the recall and will supervise the destruction of the food.
The council added that it was an isolated incident.
There was no-one from Skelfayre available for comment.
