Horse DNA was discovered in canned sliced beef on sale at Home Bargains in Grantham in tests carried out by Lincolnshire County Council Trading Standards.
Officers took samples from the store, in the Sankt Augustin retail park, on September 3 during routine tests which began when the horse meat scandal erupted earlier this year.
The 320g packs were labelled as ‘Food Hall Sliced Beef in Rich Gravy’ and were manufactured in Romania. They were supplied to Home Bargains and Quality Save stores in the UK.
Samples were found to contain horse DNA at a level of between one and five per cent.
The meat was withdrawn from sale and Trading Standards in Liverpool, where Home Bargains’ head office is based, was made aware.
Customers who have bought the contaminated meat are advised to return it to the store where they bought it. The affected batch has a ‘best before’ date of January 2016 and a batch code of 13.04.C.
Batches manufactured after that date are not affected.
