Travel limitations impact Arizona pet owners following screwworm outbreak | Local News

Public health experts in Tucson are addressing the recent detection of New World screwworm (NWS) in Arizona, with five confirmed cases involving two dogs, two horses, and one sheep across Cochise, Greenlee, and Graham counties. Officials advise residents to check pets and livestock daily for wounds and maggots. To combat the issue, the USDA is releasing millions of sterile male flies in infested areas to mate with females, producing sterile eggs to gradually reduce the population. Additionally, Arizona residents traveling to California or Florida with pets will require a certificate of veterinary inspection to confirm their animals are free of screwworms.
