The spread of New World Screwworm (NWS) continues to raise concerns in North America after Mexican authorities confirmed new cases in the states of Nuevo León and Coahuila, located just 52 to 55 miles (84-89 km) from the US border.
According to USDA, there are currently 2,072 active cases in Mexico, although no confirmed or suspected cases have been reported in the United States. To contain the pest, USDA continues releasing 100 million sterile flies per week in Mexico and along the border region to suppress populations and prevent northward spread.
Animal health officials emphasize that early detection will be critical to keeping the pest out of the US. Producers and veterinarians are being urged to closely monitor livestock wounds, as infestations are often first detected by the distinctive odor caused by screwworm larvae in affected animals.
As the pest moves closer to the border, US Customs and Border Protection (CBP) has launched an awareness campaign across Texas to inform travelers and livestock producers about the threat and reinforce preventive measures.
