Georgia agriculture officials have expanded animal entry requirements following the detection of New World screwworm in the United States, a livestock pest that was eradicated from the country decades ago.

The Georgia Department of Agriculture says the enhanced interstate movement requirements apply to all warm-blooded animals entering Georgia from Texas, as well as four counties in New Mexico: Eddy, Chaves, Lea, and Roosevelt.

New World screwworm is a parasitic fly whose larvae feed on the living flesh of warm-blooded animals. Livestock, pets, and, in rare cases, people can be affected. Any open wound can become a target for the pest.

Animals coming from an infested zone in South Texas must obtain a Georgia entry permit before entering the state. The permit must be requested at least 48 hours in advance by emailing galivestockpermits@agr.georgia.gov.

Animals coming from other areas of Texas or the affected New Mexico counties must have a Certificate of Veterinary Inspection showing they are free of New World screwworm. That certificate must be issued within seven days of travel.

The issue is especially important for livestock owners, animal transporters, veterinarians, and agricultural producers across Northwest Georgia, including Chattooga County, where cattle, horses, goats, sheep, and other animals are routinely moved for sale, shows, breeding, and farm operations.

State officials say the added requirements are intended to help protect Georgia’s livestock industry and prevent the spread of the pest into the state.
