NWS Animal Movement

Moving live animals plays a major role in the spread of invasive pests like NWS. Emergency state and federal restrictions are currently in place.

In response to the rapidly evolving New World Screwworm (NWS) outbreak in the Southwestern United States, South Carolina has changed its import requirements for states affected by NWS-infested and adjacent surveillance zones. Animals originating from states not affected by NWS infested and adjacent surveillance zones follow normal importation requirements.

All animals arriving from a state affected by an infested zone must be inspected within 24 hours of arrival for fly strike at the destination site. The USDA Best Practices for Evaluation of Animals for NWS are recommended as guidance in completing the inspection. If an infestation is found, the owner will contact Clemson University Livestock -Poultry Health at (803) 788-2260 to speak with an animal health program manager for further instructions.
