Arizona has confirmed its first case of New World screwworm, affecting a domestic dog in Cochise County, which shares a border with Mexico. The USDA reported this discovery, emphasizing the serious risks posed by the parasite, which feeds on living tissue, potentially causing severe wounds and economic impacts if left untreated.
State Veterinarian Ryan Wolker noted that the state has been prepared for such occurrences, highlighting extensive outreach and coordination efforts to educate veterinarians and pet owners on detection and reporting. The dog is currently receiving veterinary care, and authorities are gathering more information.
As of now, there are 71 confirmed cases of screwworm in Texas, New Mexico, and Arizona, with 18 remaining active. The New World screwworm was first reported in the U.S. in June in Texas, indicating a growing concern for livestock and wildlife health.
