While several years have since passed, who could forget the breaking news of 2013 that Tesco’s beef products were up to 100% horsemeat? The story broke in January of that year, after the Food Safety Authority of Ireland (FSAI) randomly tested the supermarket chain’s frozen beef burgers and other frozen meals in November of 2012. The DNA tests revealed that over one third of the burgers contained horse meat, while 85% of the products tested contained pork; but more alarmingly, these tests pointed to a massive breakdown in the traceability of the food manufacturing supply chain. Investigations in the ensuing months would shed light on an industry plagued by criminal activity and opaque distribution practices.
