Idaho imposes new animal entry requirements after New World screwworm detection

BOISE, Idaho (KIFI) — Idaho is implementing new entry requirements for animals following the detection of New World screwworm in Texas and New Mexico.

The Idaho State Department of Agriculture announced the restrictions Tuesday after the U.S. Department of Agriculture confirmed the first U.S. case of New World screwworm in Zavala County, Texas, on June 3.

New World screwworm is a parasitic pest that can infect livestock, pets, wildlife and, in rare cases, humans. According to ISDA, the larvae burrow into living tissue, causing severe wounds and potentially significant economic losses for producers.

"Idaho has been preparing for the possibility of New World screwworm reaching the United States, and we are well-positioned to respond," ISDA Director Chanel Tewalt said. "These state-entry requirements reinforce the critical role that pet owners, livestock producers and animal health professionals play in helping the state respond to the threat posed by New World screwworm."

To help prevent the spread of the pest into Idaho, state agriculture officials have issued an administrative order establishing additional entry requirements for warm-blooded animals entering the state.

Animals coming from a designated New World screwworm-infested zone must have a Certificate of Veterinary Inspection issued within five days before entering Idaho, along with a movement permit from the state of origin authorizing the animal to leave the infested area.

Animals coming from a state where New World screwworm has been detected, but outside an officially designated infestation zone, must also have a Certificate of Veterinary Inspection issued within five days before entering Idaho.

Pets are not immune to the parasite including dogs and cats, State Veterinarian Scott Leibsle urged pet owners to use caution when traveling to affected states.

"Dogs and cats are just as susceptible to the pest as livestock," Leibsle said. "Owners who do decide to travel with their pets to states affected by New World screwworm will be required to get a health certificate from a veterinarian in that state within five days of their return to Idaho."

Agriculture officials are encouraging anyone who suspects a New World screwworm infestation to immediately contact a veterinarian. The pest is considered a mandatory reportable disease.

More information, including the full administrative order and a map of affected areas, is available through the Idaho State Department of Agriculture.
