Two coolers of meat found Wednesday in Miami-Dade County, Fla., have been confirmed to contain horsemeat.

Officers discovered the coolers in a van, parked in a Miami neighborhood known for the sale of black market horsemeat. The U.S. Department of Agriculture conducted tests on the meat and confirmed it to be horse. A bag containing horse legs was later found in the vehicle.

According to TheHorse.com, the van’s owner, Ramon Clemente, and a friend, Modesto Chavez-Villa, have been arrested by the Miami-Dade Police Dept. They were charged with loitering and prowling.
