New World Screwworm Update

Newly identified NWS case within 70 miles of the US border (Texas).

Everyone be vigilant and report any suspicious cases. Typically we (AZDA) usually conducts anywhere between 6-12 parasite ID Foreign Animal Disease investigations every year and they often come back as Green Bottle Fly or some Cuterebra species. If anyone is seeing any maggots well entrenched and feeding on live / bleeding tissue (not necrotic tissue), and especially if the maggots are vertically arranged, please call or email the AZDA Office of the State Veterinarian immediately.
