National Milk Testing Strategy (NMTS) PCR Tests


On May 19, 2025, the Wisconsin Department of Agriculture, Trade and Consumer Protection announced that Wisconsin would soon begin testing as part of the USDA Animal and Plant Health Inspection Service (APHIS) National Milk Testing Strategy (NMTS). With the help from industry partners, Wisconsin is sampling milk at the farm level with the goal of testing each farm approximately every month.


This site will be updated weekly as the testing continues. DATCP expects to continue to be able to utilize samples that are already collected for routine milk testing to streamline the testing process.

Excerpt:
\As of October 1, 2025, Wisconsin transitioned to 50% reduced testing frequency while maintaining the state's commitment to ongoing surveillance pursuant to the NMTS. DATCP continues to utilize milk samples that are already collected through existing, routine sampling to streamline the NMTS testing process.

Access the updated November 23-29, 2025 milk testing numbers on DATCP's website. To date, more than 23,000 milk samples have been tested as part of the NMTS. H5N1 has not been detected in any of the PCR tests. These tests represent nearly all licensed dairies in Wisconsin, with continuing verifications underway to ensure complete statewide reach. The DATCP H5N1 in Dairy Cattle webpage will continue to be updated weekly as the testing continues.
