In summer 2016, Spanish environmental authorities found irregularities in the trade of horsemeat, which they found to be incorrectly labeled and exported.
"The investigation revealed the existence of an organization which acquired horses which were in bad condition and old and not apt for consumption and sacrificed them in two specific slaughter houses", a spokesman for the Civil Guard added.
The group is suspected of having modified the horse's microchips and documentation to pass off the meat as edible. The animals were slaughtered and processed, then sent on to Belgium, which is among the largest horsemeat exporters in the EU. This action was coordinated by the Federal Police, the Federal Food Agency in Belgium and Guardia Civil.
Mislabelled meat products were later found on supermarket shelves in a number of European countries, including the UK.
