U.S. Customs and Border Protection found 42 pounds of horsemeat “and other ruminant meat, including 13 pounds of horse genitals, and three liters of yak milk” inside the bags of two women at Dulles Airport on January 29.

CBP’s agriculture officials discovered the items during a routine agriculture exam after the women arrived from Mongolia, according to a CBP release. Officials say that one of the women claimed the horse genitals, which were concealed inside juice boxes, were for medical purposes.

While the agency “takes no pleasure in seizing and destroying travelers’ food products,” some items just aren’t allowed, said Wayne Biondi, CBP port director for the Area Port of Washington Dulles. That list also includes raw black chickens.

CBP officials treat horsemeat as “unknown ruminant meat and seizes it due to fears of foot and mouth disease,” according to the release. The only time it’s permitted is if it is accompanied by a government certification from its origin country.

The women’s items were incinerated, and they were free to enter the country with no criminal charges for bringing the items.

On an average day, CBP’s agriculture specialists across the country inspect over 1 million people, and air and sea cargo. About 4,638 materials including plant, meat, animal byproduct, and soil end up getting quarantined.
