Flesh-Eating New World Screwworm Making a Comeback in States Surrounding Oklahoma
The parasite has infected more than 120 animals since June, and officials say cattle and sheep are the main livestock at risk.
- The New World screwworm has spread to Eddy County, with more than 120 animals detected since June. November already marks the highest case count recorded.
- Dr. Jonathan Cammack, Oklahoma State University extension specialist, warned that livestock trailers can transport cows 600 miles daily, stating, "Really, our concern is livestock."
- The parasite lays eggs in open wounds where larvae feed on living tissue. Cammack noted current case numbers are the highest the United States has seen since 1979.
- Oklahoma State University experts told KOCO 5 that cooler temperatures favor the state. Cammack said, "It is highly unlikely that we will see a natural infestation occur in the state of Oklahoma."
- Hunters are asked to remain vigilant for signs including restless behavior or licking of wounds. Officials urge immediate reporting of any suspected larvae to protect livestock and wildlife populations.
