(NBC NEWSCHANNEL) Customs inspectors were confronted with a slimy situation at Los Angeles International Airport.
It was a case of snails on a plane as inspectors seized a live shipment of 67-giant African snails from Nigeria.
The paperwork stated the snails were for human consumption.
Authorities say they were intercepted July 1.
They were subsequently identified after a sample was sent to U.S. Department of Agriculture specialists in Washington, D.C.
The giant African snail is prohibited because it poses a serious threat to agriculture, consuming at least 500 types of plants.
The snails can also carry a parasitic nematode that can lead to meningitis in humans.
Officials say the snails were disposed of through incineration.
Palm Beach County agricultural officials are concerned they could move north.
The Florida Department of Agriculture is urging anyone who suspects they see giant African land snails to call 1-888-397-1517.
