The Food Safety Authority of Ireland (FSAI) have discovered that some burgers sold in UK supermarkets Aldi, Iceland, Lidl and Tesco contained horse DNA. In most cases it was found in very low levels although in the Tesco Everyday Value Beef Burgers the level of positive DNA indicated horsemeat accounted for 29% relative to the beef content. Products have all been withdrawn from the shelves.
