On June 3, 2026, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service confirmed the detection of a New World screwworm (NWS) in a 3-week-old calf in Zavala County, Texas. There has not been a confirmed case in Kansas at this time, and the Kansas Department of Agriculture’s Division of Animal Health is actively working in alignment with the USDA’s established strategies to respond to a confirmation of NWS in the U.S., including restrictions on animal movement from the infested zone. 

The best way to protect your pets from any issues:​

  • Wound Care: Properly clean, dress, and monitor any minor scratch, cut, or surgical incision. Female flies are drawn to wound discharges and body secretions.

  • Limit Exposure: Avoid travel to infested areas or regions where active outbreaks are occurring, such as the U.S.-Mexico border or parts of Latin America.

  • Professional Intervention: If you find a wound with what appears to be maggots, do not attempt to treat it yourself. Visit your local veterinarian immediately to remove the larvae and test for NWS.
