Human case of flesh-eating screwworm: What to know
The New World screwworm has for the first time in years infested a human in the U.S. and federal officials are working to prevent the parasitic creature from getting into the food supply.
The U.S. battled an infestation of the screwworm decades ago and earlier this year closed the southern border to livestock imports over fear U.S. livestock could be infested, as Deseret News earlier reported.
