The work continues to prevent the highly pathogenic avian influenza from disrupting dairy herds. Several states have had the virus infiltrate dairies, but Wisconsin is not one of them. The goal of state health officials is to keep it that way. Dr. Heather Roney is a veterinarian and epidemiologist with the state Department of Agriculture, Trade and Consumer Protection's Division of Animal Health, overseeing state cattle programs. She says Wisconsin's dairy industry is different from the other top dairy-producing states that have struggled with the virus -- we're not bringing in a lot of lactating cows. This benefits our dairy industry in preventing the spread of HPAI/H5N1. Wisconsin is currently under two federal orders and one state order regarding lactating dairy cattle testing. Roney says even dairy farmers who are not required to test their milk are volunteering to test and being proactive.
