Effort begun to eradicate giant African snails in Florida

They consume hundreds of varieties of plants and carry diseases that affect humans

Invasive giant African land snails that can eat building plaster and stucco, consume hundreds of varieties of plants and carry diseases that affect humans have been detected once again in Florida, where officials said Thursday work has begun to eradicate the pests.

The snails, which grow as long as 8 inches (20 centimeters) and have a distinctive whirled, brown mottled shell, were confirmed by state agriculture officials in New Port Richey, Florida, on June 23. The location in Pasco County is just north of the Tampa Bay area on the Gulf coast.

Now they are back again, most likely the result of the illegal international exotic pet trade or arriving hidden in cargo from overseas.
