LONDON, Oct 24 (Reuters) Shops across Britain have withdrawn batches of lamb after it was found they were unfit for human consumption, the Food Standards Agency said today.
Supermarket Asda and wholesaler Makro have pulled the lamb and offal products, distributed by Welsh Country Foods, after it was found they might contain meat from sheep sold for breeding purposes.
''Some of the sheep had been treated with veterinary drugs to combat sheep scab that was not given enough time to pass through the animals' systems,'' the FSA said in a statement.
One of the drugs, Doramectin, had been found to cause sickness and other effects in laboratory animals repeatedly exposed to it.
Asda recalled the products last Friday while Makro has also withdrawn the lamb from sale and displayed notices in its stores.
''The likelihood of people eating meat from the affected part of the animal is very low. However, as a precautionary measure, Asda has removed batches of lamb from sale that could be affected,'' the supermarket said in a statement.
The FSA said the batches, which should not have entered the human food chain, had been distributed to other premises and its investigations were continuing.
