Call it a slimy discovery.
After a Pearland family saw it in their backyard, the Texas Invasive Species Institute confirmed that the worm that family found was indeed the New Guinea Flatworm, and warned her that the worm can be harmful to your health.
According to TISI's website, the New Guinea Flatworm is only found in Texas, Florida and Puerto Rico in the United States. It can potentially carry parasites, posing a threat to humans and other mammals.
The CDC says the rat-lung parasite these worms can carry can cause eosinophilic meningitis and severe gastrointestinal or central nervous system disease in humans, depending on the species.
