New testing required for dairy cattle participating in Iowa fairs

CEDAR RAPIDS, Iowa (KCRG) – On Tuesday, the Iowa Secretary of Agriculture announced new testing requirements for dairy cattle participating in Iowa fairs and exhibitions.

Secretary Mike Naig announced the new requirements as a way to minimize the potential spread of Highly Pathogenic Avian Influenza (HPAI). HPAI (also known as Bird Flu) has hit numerous dairy cattle in the state. The Secretary says the state should expect to see new positive cases announced as the increased testing takes place.

“The Department is issuing a statewide order effective July 1 that will require additional tests for HPAI prior to dairy cattle participating at our state’s many fairs and exhibitions,” said Secretary Naig. “We want to strike a balance between allowing our 4-H, FFA, and dairy exhibitors the opportunity to show their animals, while also requiring additional testing to protect our livestock and minimize the potential spread of the virus,” said Secretary Naig.

To date, the state has reported 11 positive cases of HPAI within dairy herds in Iowa. 9 of those cases have been detected in Sioux County. Iowa has had three poultry cases thus far in 2024, including one case in a commercial chicken layer in Sioux County and two cases in commercial turkey flocks.

“Highly Pathogenic Avian Influenza isn’t just a poultry issue or a dairy issue, it’s an issue for all of agriculture. Our approach is reflective of our significant livestock industry, and I want to thank our farmers who have stepped up to help contribute to the broader understanding, visibility and knowledge of this virus,” said Secretary Naig. “We should expect additional challenges ahead and as the situation continues to evolve, we will also continue to evaluate our response. We continue to support our farmers through the joint state and federal response team who are navigating this evolving and unpredictable situation.”

Suspected signs of HPAI in poultry include:

• Sudden increase in bird deaths without any clinical signs
• Lethargy and/or lack of energy and appetite
• Decrease in egg production
• Soft, thin-shelled and/or misshapen eggs
• Swelling of the head, eyelids, comb, wattles, and hocks
• Purple/blue discoloration of the wattles, comb, and legs
• Difficulty breathing
• Coughing, sneezing, and/or nasal discharge (runny nose)
• Stumbling and/or falling down
• Diarrhea

Suspected signs of HPAI in dairy cows include:

• Decrease in food consumption with a simultaneous decrease in rumination
• Clear nasal discharge
• Drop in milk production
• Tacky or loose feces
• Lethargy
• Dehydration
• Fever
• Thicker, concentrated, colostrum-like milk

Officials say that it is safe to enjoy poultry products. Consumers should utilize the proper handling and cooking of eggs and poultry products, including cooking to an internal temperature of 165˚F.

There is no concern about the safety of pasteurized milk or dairy products. Pasteurization has continually proven to successfully inactivate bacteria and viruses, like influenza, in milk.

If dairy producers suspect cases of HPAI, they should contact their herd veterinarian immediately. Possible cases must also be reported to the Iowa Department of Agriculture and Land Stewardship at (515) 281-5305.
