Horse Near Tucson Confirmed as Arizona's Seventh New World Screwworm Case; Quarantine Zones Now in Four Counties

The Arizona Department of Agriculture reported on Nov. 13 that a horse near Tucson has been confirmed infected with New World screwworm, the state's seventh case in three weeks and the first found in Pima County. The department immediately established a new quarantine zone with a radius of 12.4 miles around the case, bringing the statewide total to four quarantine zones, in Cochise, Greenlee, Graham, and Pima counties. The seven cases involve four horses, two dogs, and one sheep. Arizona's first case was found on Oct. 28 in a dog near Elfrida in Cochise County, and the outbreak has since spread gradually westward.

The department urged pet owners, ranchers, and hunters to report immediately to the department if they find maggots in an animal's wound, by email at [email protected]. The department and the University of Arizona's Livestock Incident Response Team will hold an online briefing from 5:30 to 8 p.m. on Nov. 16 to explain the outbreak and response measures and answer questions. At least nine states now require veterinary inspection before animals from Arizona may enter.
