What is screwworm and
what causes it?
Screwworms are the larvae (maggots)of a certain fl y species that feed on living tissue of animals.
Although these flies have been eradicated from the United States, Mexico and Central America, they can still be found in some countries of South America,the Caribbean, Southeast Asia, India and Africa.
One of the concerns with this parasite is that it will be reintroduced into the United States from an infested animal.
The larvae cause great damage to the hides of animals as well as have the potential to cause death in affected animals.
