As of June 2026, there are confirmed cases of NWS in Texas and New Mexico. The U.S. Department of Agriculture (USDA) is using various strategies to combat this threat. Wisconsin, which receives animals from southern states where NWS risk is highest, has modified its import requirements.
New Regulations
Under the new temporary order, animals imported into Wisconsin from states with active NWS-infested zones must meet additional requirements. Animals not originating from an infested zone must have a Certificate of Veterinary Inspection (CVI) stating they did not originate from an NWS-infested area. Animals originating from an infested zone may not enter Wisconsin unless the importer receives a DATCP-approved permit at least 48 hours prior to movement, and the CVI includes statements confirming the animals’ origin, a visual inspection within five days of movement showing no evidence of NWS, and details of any treatment administered.
Animal owners, veterinarians, and producers are encouraged to remain vigilant for signs of NWS and to maintain strong biosecurity practices. Monitoring all animals individually and inspecting for wounds or larvae, especially after travel, remains our best defense against this parasite.
