The 2013 meat adulteration scandal is ongoing in Europe; foods sold as containing beef were found to contain undeclared horse meat, as much as 100% of the meat content in some cases,[1] and other undeclared meats, such as pork.[2] The issue came to light on 15 January 2013, when it was reported that horse DNA had been discovered in frozen beefburgers sold in several Irish and British supermarkets. While horsemeat is not harmful to health and is eaten in many countries, it is considered a taboo food in many countries including the UK and Ireland, in addition to being a lower-cost ingredient than beef.
