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."
The horsemeat scandal demonstrates how long and complicated the food chain we all depend on is. Regulating our food supply is expensive.
Some of the best, and worst, jokes and gags from Twitter users discussing the discovery of horse DNA in some supermarket beef burgers.
We've seen the jokes on Twitter but the discovery of horse and pig DNA in beefburgers poses a serious question; where did it come from?
