CNN:

The discovery of horse DNA in hamburgers on sale at supermarkets in Ireland and Britain is testing the appetite of meat lovers there.
The Food Safety Authority of Ireland said Tuesday that 10 out of 27 hamburger products it analyzed in a study were found to contain horse DNA, and 23 of them tested positive for pig DNA.

In nine out of the 10 burger samples, the horse DNA was found at very low levels, the authority said, but in one sample from Tesco, Britain's largest retailer, the horsemeat accounted for about 29% of the burger.

I wonder if this has anything to do with the whole austerity thing.
