U.S. Customs and Border Protection (CBP) agriculture specialists intercepted six Giant African Snails at Detroit Metropolitan Airport.

The live snails were discovered in the suitcase of a traveler who arrived in the U.S. from Ghana.

While intended for direct consumption, the snails pose significant health risks to humans and the environment and are considered an invasive species. The snails were subsequently seized for further analysis.

“Our CBP officers and agriculture specialists work diligently to target, detect, and intercept potential threats before they have a chance to do harm to U.S. interests,” said Port Director Robert Larkin. “The discovery of this highly invasive pest truly benefits the health and well-being of the American people.”

Giant African Snails can carry a parasitic nematode that can lead to meningitis in humans and due to an appetite that includes at least 500 different types of plants, along with plaster and stucco, they can cause significant damage to structures and ecosystems. They are considered a prohibited organism in the U.S., though they are popular for consumption and even kept as pets in other countries.
