Pet Travel Warning in Arizona Due to New World Screwworm Threat
Arizona wildlife officials are advising families planning to travel to Mexico to leave their pets at home as the New World screwworm approaches the state. The parasite, known to infest animal wounds, has been detected in Sonora, Mexico, with the closest U.S. case reported recently in Grant County, New Mexico, approximately 50 miles from Arizona.
Although primarily affecting livestock like cattle and horses, the screwworm can also impact pets and, in rare instances, humans. Symptoms in animals may not always be visible, but behavioral changes such as depression or hiding may be observed.
Wildlife veterinarian Ann Fann from the Arizona Department of Game and Fish recommends against taking pets to Mexico, noting that veterinary inspections and treatments are needed both before departure and upon return to Arizona. She emphasizes the heightened risk associated with traveling to affected areas.
The screwworm outbreak poses potential economic consequences for the livestock industry, recalling a similar 1976 outbreak that resulted in about $375 million in damages in Texas alone. Restrictions on cattle movement and the necessity for extensive treatments can lead to significant costs.
If you suspect an infestation in your pet after visiting an affected area, officials urge you to contact a veterinarian immediately.
