Mexico confirmed another case of New World screwworm (NWS) was found in a calf in Nuevo León in the city of Montemorelos, about 125 miles south of the U.S. border.
Mexico’s National Agro-Alimentary Health, Safety and Quality Service said the case was found in one calf in a shipment of 85 head that originated from the southeast part of Mexico.
“However, the larvae were dead and poisoned by the antiparasitic ivermectin and the larvicidal dip that are mandatory in the double treatment established as part of the new protocol against (NWS),” the agency said in a news release translated from Spanish.
The case is not related to the earlier case found in late September in Sabinas Hidalgo, Nuevo León, the agency said, which was declared inactive on Oct. 5.
Texas Agriculture Commissioner Sid Miller said the state is utilizing Swormlure-5 as bait to attract and kill NWS flies. “The time is now for our state and federal partners to get on board with the deployment of pesticide bait,” Miller said. “When utilized right, alongside TDA Swormlure, this is a proven method for eradication.” He added, “This isn’t just a livestock issue, it’s about protecting Texas jobs, rural communities, and our agricultural lifeblood.”
