Scientists are raising alarms about the potential spread of the New World screwworm in the United States, linking its movement to illegal cattle trafficking from Central America.
Conservationists monitoring remote forests have documented wildlife infected with the parasite, underscoring the urgent need for effective control measures.

Wildlife Infections Signal Endemic Spread
Jeremy Radachowsky, director of the Mesoamerica and Caribbean program at the Wildlife Conservation Society, stated, "We see infestations in the deepest parts of the interiors of the forest, so now it's become endemic in wildlife, far from the cattle infestations."
This indicates a troubling trend in the fly's spread beyond its usual livestock hosts.
The screwworm has been identified in 34 animals across the US, primarily in Texas and New Mexico, though no wildlife cases have been reported yet.
Current eradication efforts include releasing 100 million sterile flies in the southwestern US and Mexico, but experts warn this is insufficient to eliminate the pest.
Phillip Kaufman, professor and department head of entomology at Texas A&M University, said, "What we lack are sufficient flies in order to start pushing the population back south."

He emphasized the need for expanded breeding facilities, with plans for new operations in Texas set for late 2027.
Innovative strategies are being considered, including the exclusive breeding of sterile male flies and improved trapping methods.
Kaufman remarked, "We can't stop doing things we know work in order to try things that don't have any data to support.
We are relying on science to solve this problem."

However, these developments will take time to implement effectively.
