CDC's Urgent Response: The Parasites Threatening U.S. Health

Federal health officials are responding to two separate parasite-related threats that have raised concerns across the United States, prompting increased surveillance, emergency coordination, and warnings for both the public and the agricultural industry.

One threat involves a foodborne parasite sickening hundreds of people in multiple states.

At the same time, the other centers on the return of a flesh-eating fly that was eliminated from the United States decades ago but has now reappeared in livestock along the southern border.
