Snails may pose a significant threat to agriculture because they cause damage by feeding on agricultural and horticultural crops as well as native plants, thereby lowering crop yields and quality. 

“CBP agriculture specialists take their job of detecting foreign invasive plants and plant pests very seriously,” said Patrick Orender, CBP Assistant Port Director for the Port of Washington Dulles. “This is another example of our agriculture specialists performing a thorough inspection and finding a new potential threat to the U.S. agriculture industry.”

The snail was discovered in a 300-stem shipment of flowers from the Netherlands destined for Fairfax, Va. CBP forwarded the snail to the USDA Animal and Plant Health Inspection Service (APHIS) - Plant Protection and Quarantine (PPQ) identifier office for classification. 

CBP issued an Emergency Action Notification to the importer requiring the shipment to be re-exported or destroyed.The importer elected to have the shipment destroyed by steam sterilization under CBP agriculture specialist supervision.

CBP agriculture specialists work closely with USDA’s, APHIS, PPQ to protect our nation’s agriculture resources against the introduction of foreign plant pests and animal diseases.
