LINCOLN, Neb -- Bird flu has been confirmed at a northeast Nebraska farm that was already voluntarily slaughtering its 200,000 chickens.
The Nebraska Department of Agriculture said Tuesday that bird flu has now been confirmed on four farms in the state, up from three.
The new test result doesn't change the agency's plan to kill nearly 5 million chickens and quarantine all nearby farms to limit the disease's spread.
The Dixon County farm where the disease was found recently is one of two where all birds are being slaughtered as a precaution. The company that owns those farms also owns several farms where the disease has been confirmed.
Workers continue to slaughter chickens on the affected farms and have begun sanitizing the facilities.
