Customs and Border Protection officers seized 42 pounds of horse meat hidden in two women's luggage.
The women were coming from Mongolia when customs agents sent them for an agriculture examination.
When they searched the bags they found the meat inside juice boxes, including 13 pounds of horse genitals.
One of the women claimed the meat was for medicinal purposes.
CBP port director for Washington Dulles airport Wayne Biondi says horse meat is prohibited from entering the US because of possible foot and mouth disease.
“We’re in the business of protecting America’s agriculture industries, like the livestock industry, from the potential introduction of animal diseases posed by these unpermitted food products.”
All of the meat was seized and was destroyed.
