A shipment of seafood at Hartsfield-Jackson Atlanta International Airport contained more than just aquatic fare; U.S. Customs and Border Protection (CBP) officers discovered the remains of 20 deceased Giant African Snails concealed within the shipment on October 4. These snails are considered a highly invasive species and pose significant agricultural and ecological threats.
Atlanta—U.S. Customs and Border Protection (CBP) agriculture specialists at Hartsfield-Jackson Atlanta International Airport made a startling discovery on October 4: nestled within a shipment of seafood were not delicacies of the sea, but the lifeless bodies of 20 Giant African Snails (GAS). This discovery underscores the ongoing vigilance required to protect U.S. agriculture and ecosystems from invasive species.
The incident began when CBP agriculture specialists conducted a routine inspection of an arriving international cargo shipment declared to contain seafood. During the examination, agents noticed anomalies within the packaging. Upon closer inspection, the specialists unearthed the deceased snails hidden amongst the seafood.
“Our agriculture specialists are highly trained and vigilant in protecting U.S. agriculture from invasive pests and diseases,” said Clay Thomas, CBP Port Director at the Atlanta airport. “This interception is a testament to their dedication and expertise in preventing harmful species from entering our country.”
The Giant African Snail is one of the most damaging land snails globally. It is known to consume at least 500 different types of plants, including agricultural crops, vegetables, and ornamental plants. These snails can cause extensive damage to ecosystems and agricultural industries. Beyond the immediate threat to plant life, GAS also poses a health risk to humans. They carry a parasitic nematode that can cause meningitis.
The intercepted snails were immediately turned over to the U.S. Department of Agriculture (USDA) for further analysis and identification. The USDA confirmed the specimens as Giant African Snails (Lissachatina fulica), a prohibited species in the United States.
“The discovery of these snails highlights the importance of our ongoing efforts to prevent the introduction of invasive species,” said a USDA spokesperson. “We work closely with CBP and other agencies to identify and mitigate potential threats to U.S. agriculture and natural resources.”
This incident marks the latest in a series of interceptions by CBP at ports of entry across the United States. The agency maintains a robust agriculture inspection program aimed at preventing the introduction of harmful pests and diseases.
The Threat of Giant African Snails
The Giant African Snail is a large, terrestrial snail native to East Africa. It has spread to many parts of the world, primarily through human activity, becoming established in various tropical and subtropical regions. The snail is considered one of the world’s most invasive species due to its rapid reproduction rate, voracious appetite, and adaptability to different environments.
- Ecological Impact: GAS can have a devastating impact on ecosystems. They consume a wide range of plant species, outcompeting native snails and disrupting food chains. Their feeding habits can lead to deforestation, soil erosion, and habitat loss.
- Agricultural Damage: GAS poses a significant threat to agricultural industries. They feed on a wide variety of crops, including fruits, vegetables, grains, and legumes. Infestations can lead to substantial crop losses and economic damage.
- Human Health Risks: GAS carries a parasitic nematode known as rat lungworm (Angiostrongylus cantonensis), which can cause meningitis in humans. Infection occurs through the ingestion of raw or undercooked snails, or through contact with contaminated surfaces.
CBP’s Agriculture Inspection Program
U.S. Customs and Border Protection plays a critical role in protecting U.S. agriculture and natural resources from invasive pests and diseases.
