The New World Screwworm outbreak in Texas presents a genuinely mixed picture as of late June 2026: new cases continue to be confirmed, even as some previously identified infestations have been successfully resolved.
The Texas Animal Health Commission has confirmed New World Screwworm (NWS) cases have reached 25 in the state, with the most recent additions occurring in sheep in Crockett and Edwards counties and cattle in Medina County — areas where quarantine measures remain firmly in effect. At the same time, three cases in the broader regional outbreak, including the single previously confirmed New Mexico detection, are now listed as inactive, indicating those specific infestations have been successfully treated and resolved.
