You may have seen recent news stories or press releases from USDA-APHIS concerning the New World Screwworm fly. These pests are typically localized to central and South America, where the US and partners try to maintain a sterile line of flies as a means of control. However, that line has recently been disrupted and NWS have been detected in Mexico, within 700 miles of the US border. These flies are known to lay their eggs in open wounds or lesions, causing very painful infections in livestock.

USDA is making progress toward control and no flies have been detected inside US borders currently.  To keep it that way, surveillance and immediate reporting will be necessary.

Join us for a webinar with the NCDA&CS Veterinary Division on June 27th at 10AM. See attached flier for more details and the zoom link. Topics covered include identification methods and response and reporting guidelines.
