Ag officials finish depopulation efforts at Jefferson Co. poultry farm with confirmed avian influenza case

MADISON, Wis. — Agriculture officials say efforts to depopulate a Jefferson County poultry farm where a case of highly pathogenic avian influenza was confirmed earlier this month have been completed.

The state’s Department of Agriculture, Trade and Consumer Protection said Wednesday all of the birds at the farm have been killed and compost disposal efforts have begun.

On March 14, DATCP confirmed a case of the highly pathogenic avian influenza, Wisconsin’s first since 2015, at a commercial poultry flock in Jefferson County. The virus doesn’t pose a threat to the public and can be killed by cooking poultry and eggs to a minimum temperature of 165 degrees.

The confirmed case led DATCP to monitor farms within 10 kilometers of where the positive case was reported. The Henry Vilas Zoo in Madison also shut down its aviary amid concerns posed by the bird flu.
