PARIS – An investigation by France’s National Gendarmerie and other officials revealed that meat from horses used in laboratory tests was sold for human consumption, according to an Associated Press report. The National Gendarmerie, along with food safety and veterinary investigators, conducted raids in 11 regions in southern France netting 21 arrests.

Some of the horses came from drug maker Sanofi-Pasteur, which stated the company is cooperating with the investigation. The company resold roughly 200 horses over three years to vet schools, individuals and professionals. Sanofi said the horses were not used for testing; rather the horses were used to create antibodies against rabies, tetanus and other diseases.
