DTW flier from Ghana tries to bring in 90 giant snails that can pose public health threat

ROMULUS, Mich. – A passenger flying from Ghana to Detroit Metro Airport tried to bring in 90 giant snails that can pose a public health threat to humans.

Officials from United States Customs and Border Protection said they double checked a passenger’s luggage on June 30, 2024, after that person declared several fresh food items.

During the inspection, agriculture specialists found a smelly, tied, woven bag. Inside that bag were 90 Giant African Land Snails.

They ranged from 3-6 inches in length. They can grow up to 8 inches.

Officials said the passenger had declared other prohibited items, like beef skin and fresh peppers, but never mentioned the snails.

Giant African Land Snails are considered an invasive species in the U.S. They were seized by authorities.

“These snails are an invasive species that could negatively impact our economy,” acting Port Director John Nowak said.

The snails were intended to be eaten, but they have a “voracious appetite” and cause major crop damage when they escape into the environment, officials said.

They can also pose a public health threat to humans.

Sometimes, these snails can cause structural damage by using stucco on houses to meet the calcium requirement for their shell growth.
