In November 2024, USDA’s Animal and Plant Health Inspection Service was notified by Mexican officials of a positive detection of New World screwworm in Mexico. NWS is a parasitic fly whose larvae feed on the living tissue of warm-blooded animals, causing serious wounds, infection, and even animal death. First discovered in a cow in the southern Mexico state of Chiapas, NWS has moved north to Oaxaca and Veracruz, within 700 miles of the US/Mexico border. As of May 11, 2025, US Secretary of Agriculture Brooke Rollins issued a suspension of live cattle, horse, and bison imports through US ports of entry along the southern border due to the continued and rapid northward spread of NWS in Mexico.
The intent of the webinar is to provide the latest information on NWS, including an overview of the parasite, the fly lifecycle, clinical signs of infestation, the status of NWS in Mexico, and efforts to mitigate incursion into the US. Join experts during this webinar as they share information on NWS and how it could impact the US pork industry.
