New World screwworm cases being monitored

(KYMA) - The New World screwworm continues to raise concerns as veterinarians are monitoring the risk of its spread toward the northern Mexican border.

The parasite affects livestock, pets, wildlife, and, in an extreme cases, even people.

Female flies lay their eggs in wounds. The larvae then feed on living tissue, causing deep and potentially life-threatening injuries. 

Arizona's economy could also be affected if the screwworm reaches the region, particularly due to the importance of agriculture and livestock to the state.

Early detection is considered a key part of prevention.

"I think the most important thing for pet owners is to pay attention to their animals' wounds," said Guillermo Arcega, PhD student at the University of Minnesota. "They are very easy to identify, as they are deep wounds."

Cattle exports from Mexico to Arizona were halted as a precaution, but they're expected to resume by the end of this month.
