4/6/2023 0 Comments Land snailIt is caused by a parasitic nematode (roundworm parasite) called Angiostrongylus cantonensis. Not only are GALS destructive, the snails also pose a serious health risk to humans by carrying the parasite rat lungworm.Īngiostrongyliasis, also known as rat lungworm, is a disease that affects the brain and spinal cord. Prior to the recent detection, the last live snail in Florida was collected in Miami-Dade County in December of 2017. 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. The giant African land snail has been eradicated twice in Florida. They feed on more than 500 host plants, can damage structures by consuming stucco to obtain the calcium necessary to build shells. This pest has a lifespan of up to eight years, the ability to grow up to eight inches long and produce 2,500 eggs per year. The GALS, Lissachatina fulica, is an invasive pest to the state of Florida and the United States. This population has a light-dark brown shell with a creamy white flesh opposed to the greyish-brown flesh of the Miami area populations. The phenotype of the population in Pasco County differs from the ones previously eradicated in the state. The FDACS reported they have so far checked 525 properties, finding snails in just 30. To date, more than 1,400 GALS were in Florida Department of Agriculture custody. Proceed east on Ridge Road, south on Little Road, west on Trouble Creek Road, north on U.S. The quarantine starts at the northwest corner of U.S. Officials set up a quarantine zone to contain them as they took steps to destroy the population. This detection was reported by a Pasco County Master Gardener. If conditions get bad for adult snails, they can bury themselves in soil and stay dormant for up to a year.NewsDesk June 23, 2022, the Florida Department of Agriculture and Consumer Services (FDACS) confirmed the detection of giant African land snail (GALS) in the New Port Richey area of Pasco County. The snails bury the eggs in cool soil and when they hatch, juvenile snails eat their eggshells and then burrow underground for up to two weeks. Once they do, one snail can lay eggs for up to 380 days and produce between 400 and 1,000 eggs in one year. Adult snails have both male and female sexual organs, but they still need to mate to produce eggs. They live on average between three and five years, but can live as long as nine years. They thrive in locations rich with limestone, marl, and even concrete and cement. These snails can survive in many environments, though they do require calcium. A population was discovered in Costa Rica in 2021, as well. It was first detected in Havana, Cuba, in 2014 and has rapidly spread across the island ever since. Compare that to other typical Florida snails, which average between 1 and 1.5 inches (2.5 and 3.8 centimeters) in length.Įxperts believe the giant African land snail is originally from East Africa, though it is now found in the Ivory Coast and Morocco, and throughout the IndoPacific Basin, the Caribbean, Brazil and northernmost Argentina. Their shells are usually light to dark brown with vertical stripes, and they can grow up to 8 inches (20 centimeters) long. These massive mollusks dwarf all others - in Florida and anywhere else on Earth. The snails are illegal to own, import or sell in Florida without a permit for these reasons.Īnd that name? They're not known as giant snails for nothing. It also advises people thoroughly wash fresh produce to prevent infection. The Centers for Disease Control and Prevention (CDC) says it doesn't know if the giant African land snails in the United States are infected with rat lungworm, but warns people should not handle the snails without wearing gloves. People also can get sick after eating contaminated produce, such as lettuce. Humans can get infected with rat lungworm if they eat raw or undercooked snails infected with the parasite. They can carry a parasite known as rat lungworm that is known to cause meningitis. They can cause extensive damage to tropical and subtropical environments, according to FDACS.īut they're also harmful to humans. They eat at least 500 different types of plants, so they're potentially devastating to Florida agriculture and natural areas. So why are these snails such a problem? FDACS says they're one of the most invasive pests on the planet. Why Are Giant African Land Snails So Bad?
