Horsemeat found in beef burgers sold in the UK

The presence of horse DNA has been found in some beef burgers sold in UK and Irish supermarkets, according to a study by the Food Safety Authority of Ireland.

Of the 27 beef burgers tested, 37% tested positive for horse DNA and 85% tested positive for pig DNA. The products were sold in Tesco, Lidl, Aldi and Iceland. The FSAI said:

"In one sample from Tesco, the level of horse DNA indicated that horsemeat accounted for approximately 29% relative to the beef content."
