The Iowa Department of Agriculture and Land Stewardship is taking the same approach to dairy cows with H5N1 as they have with poultry sites positive for bird flu by testing nearby farms.

Secretary of Agriculture Mike Naig told DTN that Iowa is the only state doing this kind of testing by drawing a surveillance zone within a 20-kilometer (approximately 12.4 miles) radius around a positive dairy site and testing farms within that zone.

“In Iowa, we have to look at these cases a little different since we have such a large poultry industry and the viruses found in dairy cows and poultry are connected,” he said. “There are three poultry sites in northwest Iowa that have top-notch biosecurity and they have tested positive. We really want to try to figure out how the virus spreads.”

The United States Department of Agriculture has a strong presence in Iowa with epidemiological teams and wildlife services doing testing at the positive sites. Naig said several research projects are also being conducted by USDA and Iowa State University College of Veterinary Medicine to find the interaction between animals.
