A positively identified case of New World Screwworms have been reported in Tom Green County (San Angelo). Unless someone hauled that animal in from somewhere else, then that would imply that there are active Screwworm flies in The Big Country. Please watch your animals for any wounds that appear infected or not healing. Contact your veterinarian if you see either.
On June 11, 2026, a Tom Green County bovine was confirmed to be infested with NWS. An infested zone is being formed around the detection and will be reflected on the TAHC interactive map once it is officially established.
