🚨 NEW WORLD SCREWWORM (NWS) INTERSTATE MOVEMENT UPDATE 🚨
Due to the detection of New World Screwworm (NWS) in the United States, Alabama, Mississippi, and Florida have recently implemented additional requirements for certain warm-blooded animals entering these states.
🐴 For horses coming from affected areas (specific counties in Texas and New Mexico):
🔹 Must have a certificate of veterinary inspection (CVI) within 5 days of travel
🔹 Specific remarks must be listed on CVI stating the horse has been thoroughly inspected and found free of evidence of NWS infestation prior to travel.
🔹 A separate entry permit or prior authorization number required per state to enter within 48 hours of travel
🔹 Documentation of any NWS treatment
🐛Unlike many maggots that feed on dead tissue, NWS larvae feed on living tissue, causing rapidly enlarging wounds, severe pain, secondary infections, and potentially death if untreated.
For practices near major horse transportation corridors (Florida, Alabama, Mississippi, Georgia, Louisiana, Texas), these transportation requirements are likely to become a routine part of interstate health certificate work until the outbreak is contained.
We will continue to keep our clients updated of any changes in travel restrictions as we are informed.
