Newport City Council’s trading standards department is working with Newport company Welsh Bros. Foods Ltd following positive test results for horsemeat.
Investigations into the source of the contamination are ongoing and a product withdrawal is being overseen.
All action being taken is in line with Food Standards Agency guidelines.
Newport schools do not use this supplier; however, investigations into whether council care homes have purchased this specific product are being carried out.
Approved supplier Welsh Bros Foods confirmed a sample of its frozen minced beef has 'potentially tested positive' for above 1% horsemeat.
The Welsh Government says it is working with the police to ensure allegations of horse meat at a plant in west Wales are dealt with.
