STERLING, Va. — U.S. Customs and Border Protection agriculture specialists have seen some really unusual things in traveler baggage at Washington Dulles International Airport over the years. From charred full monkeys, to voodoo ceremony tools, to cocaine concealed inside the cavity of fully cooked chickens, to live sea horses and giant African land snails. So it seems that after a while, the oddity is not so odd anymore. Then two women arrived from Mongolia on January 29 with horse meat concealed inside juice boxes, including 13 pounds of horse genitals that one woman claimed were for medicinal purposes. After they deplaned, CBP officers referred the women for a routine agriculture examination. There, CBP agriculture specialists discovered a combined 42 pounds of meat described as horse meat and other ruminant meat, including 13 pounds of horse genitals, and three liters of yak milk.
