New Jersey’s Dairy Industry Advances to H5N1 influenza “Unaffected” Status in the USDA’s National Milk Testing Strategy
New Jersey’s dairy herds have tested free of H5N1 avian influenza virus through testing milk collected at the processing plants and/or bulk tanks since the beginning of 2025. As a result, New Jersey’s dairy industry is now classified as “Unaffected” by the disease statewide. There have been no H5N1 detections in cattle, sheep, goat, or pigs in New Jersey. Due to the “unaffected” status, New Jersey dairy herds have now advanced to Stage 4 of the USDA’s National Milk Testing Strategy (NMTS) program. Learn more at:
