This Flesh-Eating Parasite Is Now Just 70 Miles From the US Border and Officials Are Sounding the Alarm
USDA and Mexican authorities intensify surveillance and control to protect livestock from NWS, with a new sterile fly facility in Texas set to release 100 million sterile flies weekly.
- On Sunday, U.S. Agriculture Secretary Brooke Rollins announced that Mexico detected New World screwworm near the U.S. border in Sabinas Hidalgo, Nuevo León.
- The parasite's advancement northward across Central America into southern regions of Mexico has led the U.S. to implement stricter border controls and restrict the importation of animals.
- The affected animal was an 8-month-old calf from southern Mexico moved to a certified feedlot near the border, and no screwworm flies have been found on the U.S. side despite extensive trapping.
- Rollins stated, "Protecting the United States from NWS is non-negotiable" and described a five-pronged U.S. response plan including an $8.5 million sterile fly facility under construction.
- The discovery near a key commercial route highlights national security risks and emphasizes the critical importance of Mexico thoroughly adhering to the joint pest control agreement with the United States.
