The people of Pasco County, Florida, have been subjected to the dreaded ‘Q’ word again — quarantine — following the discovery of a giant snail that can harm humans, wildlife and even houses. Florida Department of Agriculture and Consumer Services confirmed the detection of giant African land snail in the New Port Richey area of Pasco County. The giant African land snail can grow to be around the sized of a human fist and has been eradicated twice in Florida in the last 50 years.
… The snails pose a serious threat to humans by carrying the parasite rat lungworm, which can cause meningitis. They also feed off 500 different types of plants and the stucco on homes.
