Customs officials at a Minnesota airport intercept a traveler attempting to smuggle a box of giraffe dung.

Customs agents at a Minnesota airport discovered that a passenger had packed an unusual keepsake in her luggage: giraffe excrement.

The passenger arrived at Minneapolis-Saint Paul International Airport from Kenya on September 29, as reported by US Customs and Border Protection.

According to the release, the passenger admitted to carrying giraffe feces, explaining she had collected the droppings in Kenya to make a necklace.

The traveler revealed she had previously used moose feces for similar jewelry projects back home in Iowa, as noted by customs officials.

The agency’s agricultural experts confiscated the box, and the excrement was properly disposed of through steam sterilization, as per protocol, the release stated.

LaFonda D. Sutton-Burke, director of field operations at the agency’s Chicago office, emphasized in the release, “There is a significant risk when bringing fecal matter into the U.S. If these items had gone unreported, someone could have contracted a disease from the jewelry and faced serious health complications.”

To bring “ruminant animal feces” into the U.S., a veterinary services permit is required, the release noted. It also mentioned that Kenya is dealing with outbreaks of African Swine Fever, Classical Swine Fever, Newcastle disease, Foot and Mouth disease, and Swine Vesicular Disease.

According to the Giraffe Conservation Foundation, giraffes are found in 27 out of 47 counties in Kenya. The foundation also highlighted that diseases have played a poorly understood role in the decline of giraffe populations across the nation.
