On 7 February 2013, it was revealed that the Findus beef lasagne range in the UK, France and Sweden and the shepherd's pie and moussaka ranges in France contained horse meat without proper declaration. The contamination may have gone on since summer 2012 according to a leaked document. Out of 18 products, 11 tested positive for horse meat. It was also revealed that some of the products sold had minced meat declared as beef that actually was 60–100% horsemeat. The source of the horse meat was a third party supplier of Comigel, the producer of the lasagne. According to the Food Standards Agency (FSA), the company had been alerted by a third-party French supplier on 4 February 2013 and tested its beef lasagne products finding over 50% of the tested products contained horsemeat. According to reports, both Findus UK and the French supplier withdrew all products related to the third party supplier. It is thought the reason for the contamination is "highly likely" to have been criminal activity.
