Batches of lamb have been pulled from supermarket shelves because they may contain traces of a potentially dangerous veterinary drug.
The affected meat and offal products from Welsh Country Foods could contain meat from sheep not meant to be eaten.
Some of the sheep had been treated with veterinary drugs, including Doramectin, to combat sheep scab.
But the drug was not given enough time to pass through the animals’ systems.
The affected batches were withdrawn from Asda and Makro Self Service Wholesalers Ltd last week. This is the list of the products withdrawn from Asda.
Any concerned customers who bought lamb from the affected batches should return it to their nearest Asda store for a refund.
Welsh Country Foods has contacted all its customers and instructed them to remove the affected products from sale.
Concerns around Doramectin relate to repeated exposure that has caused sickness and other effects in laboratory animals.
Asda has also had to withdraw batches of its own-brand jaffa cakes and cans of its Baked Beans in Tomato Sauce (215g) due to allergy scares.
The Asda Jaffa Cakes (12, 24 and 36 in a pack, with batch codes that go up to and include best before 11 February 08) were found to contain milk, which was not shown on the label.
Asda has also withdrawn cans of its Baked Beans in Tomato Sauce (215g, with a best before date of end of October 2009; and a production code: 7276) as some cans of Asda Beans and Sausages had been wrongly labelled as Beans in Tomato Sauce.
This meant they contained wheat and gluten, which was not shown on the label, and were therefore unsafe for people allergic or intolerant to wheat and gluten.
