US federal customs agents pooh-poohed the plans of an Iowa woman who wanted to make jewellery from giraffe feces she picked up on a trip to Kenya and brought back to the US in her luggage. The woman, who was not identified, told officials she planned to use the waste to make a necklace, as she had done in the past with moose poop.

The woman declared the small box of feces when she was selected to have her belongings inspected upon arriving at the Minneapolis-Saint Paul Airport on Sept. 29, according to US Customs and Border Protection.

Giraffe poop can be brought back to the US with the proper permits and inspections, according to Minnesota Public Radio. The station reported that the woman won’t face sanctions because she declared the feces and gave it to Customs.

The agency’s agriculture specialists destroyed the sample.

“There is a real danger with bringing fecal matter into the US,” Customs and Border Protection’s Chicago field Director LaFonda D. Sutton-Burke said in a statement. “If this person had entered the US and had not declared these items, there is high possibility a person could have contracted a disease from this jewellery and developed serious health issues.”

African swine fever, classical swine fever, Newcastle disease, foot-and-mouth disease and swine vesicular disease are among ailments in Kenya that Customs cited as risks.
