JOHNSON COUNTY, Iowa (KCRG & USDA) – This week, the USDA announced cases of bird flu had been found in dairy cows in a few states; Texas, Kansas, and Michigan. Iowa currently isn’t one of those states, but cattle farmers are keeping a close eye it. Last year, the avian flu killed nearly 3 million birds in the state of Iowa. That ranges from commercial poultry farms to backyard flocks.
Iowa State Extension Dairy Veterinarian Phillip Jardon said cows in Texas had contracted an unknown illness, which reduced milk production in older cattle. It wasn’t until this week he said pathologists learned it was the bird flu, but they aren’t sure how it happened.
Jardon said in each of the found cases in Texas, dead birds had been found near the farm. While he said the findings are all still new and research was being done, so far, the virus doesn’t seem to be as deadly to cattle. Jardon said it would still be a good idea for farmers to be vigilant as they get closer to starting selling and moving cattle this season.
In its latest report, the USDA said ” There continues to be no concern about the safety of the commercial milk supply because products are pasteurized before entering the market, or that this circumstance poses a risk to consumer health. Dairies are required to send only milk from healthy animals into processing for human consumption; milk from impacted animals is being diverted or destroyed so that it does not enter the human food supply.
In addition, pasteurization has continually proven to inactivate bacteria and viruses, like influenza, in milk. Pasteurization is required for any milk entering interstate commerce for human consumption. FDA’s longstanding position is that unpasteurized, raw milk can harbor dangerous microorganisms that can pose serious health risks to consumers, and FDA is reminding consumers of the risks associated with raw milk consumption in light of the HPAI detections.”
