A Florida county is under quarantine due to the discovery of a fast-growing population of invasive giant African land snails.

The Florida Department of Agriculture and Consumer Services (FDACS) confirmed there were giant African land snails in the New Port Richey area of Pasco County on June 23, according to FDACS' website.
The snails pose a health risk to humans because they carry a parasite called rat lungworm, which can cause meningitis, Christina Chitty, a public information director at FDACS, told CNN.They can produce up to 2,500 eggs per year, so the population is difficult to control.

According to Chitty, the population in Pasco County likely originated from the illegal pet trade. Giant African land snails are illegal to own as pets in the United States. But some exotic pet owners still keep the invasive pests. If the owners discard them into the wild or accidentally lose them, they can quickly establish a foothold, feeding on over 500 different plant species and even consuming the paint and stucco off houses as a source of calcium.

... The quarantine took effect June 25 and prevents residents from moving the snail or related items, like plants and soil, in or out of the designated quarantine area. Residents who think they have spotted a giant African land snail are advised to call the FDACS hotline and avoid touching the snail without gloves on due to the meningitis risk.

Giant African Land Snail

The giant African land snail is one of the most damaging snails in the world and consumes at least 500 different types of plants. These snails could be devastating to Florida agriculture and natural areas as they cause extensive damage to tropical and subtropical environments. The snails also pose a serious health risk to humans by carrying the parasite rat lungworm, known to cause meningitis in humans. Giant African land snails are illegal to import or possess in the United States without a permit.

The giant African land snail has been eradicated twice in Florida. The first detection was in 1969 and was eradicated in 1975. The most recent eradication of this pest was in 2021 from a detection in 2011 in Miami-Dade County. Prior to the recent detection, the last live snail in Florida was collected in Miami-Dade County in December of 2017.

Pasco County Program Information

On June 23, 2022, the Florida Department of Agriculture and Consumer Services (FDACS) confirmed the detection of giant African land snail in the New Port Richey area of Pasco County. This detection was reported by a Pasco County Master Gardener.

FDACS's Division of Plant Industry has begun to survey the area, enacted a quarantine and will begin treatment for this detrimental pest on June 29, 2022. FDACS will treat properties with a metaldehyde-based molluscicide (snail bait). The treatment is labeled by the U.S. Environmental Protection Agency for residential use.
... A quarantine is in place starting at the northwest corner of U.S. Highway 19 and Ridge Road. Proceed east on Ridge Road, south on Little Road, west on Trouble Creek Road, north on U.S. Highway 19 (see map).
