Flesh-Eating Parasite Has Iowa Livestock Farmers on Alert

A flesh-eating parasite not seen in the United States since the 1960s has Iowa livestock farmers on high alert.

The New World Screwworm Returns

The U.S. Department of Agriculture has confirmed five cases of the New World Screwworm, according to CBS2. So far, cases have been reported in Texas and New Mexico. The flying larvae pose a big threat to the nation's cattle industry. Officials say that the Screwworm feeds on living flesh, rather than dead animals, laying eggs in open wounds, according to CBS2. The parasite isn't just a threat to cattle. It can infect other wildlife, pets, and even humans.

Watch Out For Signs of Illness

How will you know if an animal is infected? Officials tell CBS2 that the animal will first start acting lethargic and separate itself from the rest of the herd. They'll stop eating and drinking, and if it isn't caught and treated in time, it can lead to death. Experts say they're not sure that the Scewworm will make it to Iowa, but that preparation and close monitoring can reduce the risk, according to CBS2. 

USDA Says Food Supply is Safe

CBS2 reports that USDA officials note that any outbreak will not affect the safety and quality of the food supply. All beef is inspected by the USDA. The Screwworm outbreak is an animal welfare issue.

The Iowa Department of Agriculture states that there are no confirmed cases of Screwworm in the state of Iowa.
