Due to the rapidly changing nature of New World Screwworm (NWS) cases in Texas and the case identified in New Mexico, the Montana Department of Livestock (MDOL) has updated the emergency order placing import restrictions on all animals coming from Texas and New Mexico.
All animals moving out of an INFESTED ZONE in Texas and New Mexico must have a permit from the state of origin as well as official identification, treatment for NWS, an interstate CVI issued within 5 days of travel to Montana, and a statement on the CVI stating that the animals have been inspected and are free from wounds and evidence of NWS infestation. These requirements should be consistent with state of origin requirements for infested zone movements.
All animals leaving a STATE WITH AN INFESTED ZONE must have a CVI issued within 5 days of travel to Montana, official ID, and a statement on the CVI stating that the animals have been inspected and are free from wounds and evidence of NWS infestation.
NWS detections are rapidly evolving. Ensure you are getting accurate information from the Montana Department of Livestock or your veterinarian if you plan on traveling.
Let's work together to protect Montana’s animals and livestock.
