The horsemeat found in burgers for sale overseas poses no health risk. However, there is no explanation for how the traces of horsemeat wound up in the offending burgers. The strange ingredient was found in burgers for sale in the United Kingdom and Ireland. According to a Jan. 15, 2013 report by Yahoo! News, several stores had meat that tested positive for horse DNA: Tesco, Dunnes Stores, Lidl, Aldi and Iceland.
Although the amount of horsemeat found in the burgers has been called "trace," one product in particular contained a whopping "29% horse meat relative to beef content." That product was Tesco Everyday Value Beef Burgers.
The mystery is how the horsemeat was found in the burgers when the plants that processed them do not process meat from horses.
Although it doesn't pose a health risk, how would you feel if you knew your burgers were tainted with horsemeat? Even though this type of meat is fit for human consumption, some people simply don't like the idea of eating horses. Meat sold in the United States was not affected.
