More avian flu detected in western Iowa as testing continues – KMPH Fox 26

SIOUX COUNTY, Iowa (KGAN) Another case of the highly contagious H5N1 avian flu, also known as the bird flu, has been detected in a herd of dairy cattle in Sioux County.

The virus affects both wild and domestic birds primarily, but has begun spreading in other animals, most notable cattle. Fortunately, cows are better able to fight the virus and ultimately recover. Experts say the nation's milk supply is in no real danger right now, as the common practice of pasteurizing store-bought milk eliminates the virus.

But last year, Iowa legalized the sale of unpasteurized milk, also known as raw milk. The FDA is warning everyone to avoid drinking raw milk, as it is unclear just how widespread the virus is. In Iowa, leaders are focusing testing efforts in areas where the flu has already been detected.

Human cases of the bird flu are rare but can be deadly. This year, a number of cases have been reported but all were from direct and prolonged contact with infected cattle.

Six cattle herds in Iowa have now been found to have infected cows, all in western Iowa. The latest case is the 4th in Sioux County. O'Brien and Plymouth Counties have each seen one case.
