• The giant African land snail was spotted by a master gardener in Pasco County, Florida; officials confirmed its appearance on June 23.
  • Giant African land snails can carry a parasite called rat lungworm, known to cause meningitis in humans and livestock.
  • A quarantine has been set into place in response.

It’s big, it’s back and it’s causing quite the ruckus: The giant African land snail has been spotted in a Florida county, sending the area into quarantine and officials out to reel the pests in.

The Florida Department of Agriculture and Consumer Services confirmed a giant African land snail was spotted June 23 in the New Port Richey area of Pasco County, about 38 miles north of Tampa. The snail was reported by a master gardener, the  department said on its website.

Giant African land snails can carry a parasite called rat lungworm, known to cause meningitis in humans and livestock, according to the U.S. Department of Agriculture. They can also reach almost 8 inches long and 5 inches in diameter, the organization said.

The snails also have been spotted in Hawaii and parts of the Caribbean over the years. Scientists have declared them “one of the most damaging snails in the world,” according to the USDA. They can consume at least 500 species of economically important agricultural plants, including cassava, cocoa, papaya, peanut, rubber and most varieties of beans, peas, cucumbers and horticultural, cultural and medicinal plants, the USDA said on its website.

And this isn’t the snail’s first appearance in Florida.

In 1966, the giant African land snail was introduced in downtown Miami.

By 1973, more than 18,000 snails had been found and destroyed along with thousands of eggs, and the snail was declared eradicated by 1975, the USDA said. 

In September 2011, the snail was reintroduced to Miami, but it was eradicated again by September 2021.
