''The UK's horsemeat scandal was in "large part" the result of a switch from UK to foreign meat suppliers in 2012 caused by an abrupt change in European regulation that the government failed to contest, according to the expert who led the Food Standards Agency's (FSA) surveillance programme for a decade.
The change meant that "desinewed meat" (DSM), a fine mince rubbed under pressure from carcasses, could no longer be called meat on packaging. DSM produced in the UK was the main ingredient in most value-range burgers, sausages, pies and kebabs and the change meant that thousands of tonnes of meat had to be sourced from elsewhere and at low cost.''
