The news keeps getting worse coming out of Minnesota, where now 44 turkey farms have reportedly been hit by the highly pathogenic H5N2 virus. Thirteen of those farms were announced today on the APHIS website, and while the count of birds on several of the farms is pending, the known number of birds affected increases by at least 400,000.
Meanwhile there are reports, not yet appearing on the APHIS website, of two more farms in Wisconsin being hit by the virus. This from the Wisconsin Department of Agriculture.

MADISON, Wisc.—The Wisconsin Department of Agriculture, Trade and Consumer Protection, in cooperation with the US Department of Agriculture is responding to a detection of H5 avian influenza in an 800,000 bird egg-laying chicken flock in Jefferson county. There are now five cases in Wisconsin. While lethal to domestic poultry, the strain of virus detected is not known to have caused disease in humans and is not expected to pose a risk to public health or the food supply.
The property was immediately quarantined and neighboring properties with poultry will be notified about the situation. Remaining birds will be depopulated and will not enter the food supply. Following USDA protocols, surveillance and testing procedures will take place at properties near the affected facility to ensure the virus has not spread.
The H5 avian influenza virus was first detected in Wisconsin at a commercial chicken flock in Jefferson County on Monday, April 13, which led to the depopulation of more than 180,000 egg-laying chickens. Since then three additional flocks were detected in Barron, Juneau and Chippewa counties bringing the total of birds destroyed to nearly 400,000 in Wisconsin. Multiple outbreaks of avian influenza have occurred most recently in Iowa, Minnesota, Missouri, Arkansas, the Dakotas and Kansas leading to the depopulation of more than 1 million turkeys and chickens since January.
Dr. Paul McGraw, Wisconsin state veterinarian, already issued a ban on poultry movement to shows, exhibitions and swap meets in Jefferson, Juneau and Barron counties. Chippewa county was added to the ban this morning.
Wisconsinites are reminded that the avian influenza virus strain currently detected in Wisconsin and the other states presents low risk to public health. Poultry meat and egg products in the marketplace remain safe to eat. As always, both wild and domestic poultry should be properly cooked.
Officials are investigating how the virus entered the flock and may not have answers for some time. Until then, backyard poultry owners and other poultry producers are encouraged to practice good biosecurity and to take steps that prevent contact between their birds and wild birds. They also should monitor their flock closely and report sick or dead birds to DATCP at 1-800-572-8981.
