The Washington State Department of Health says 16 people have been diagnosed with salmonella after coming in contact with live poultry.
Five people have been hospitalized, but no deaths have been reported.
Those infected are from Chelan, Clark, Cowlitz, Grays Harbor, King (2), Kitsap, Kittitas, Lewis, Mason, Pierce (2), Snohomish, Yakima (2), and Whatcom counties. Seven of the 16 are children younger than the age of five.
The Centers for Disease Control and Prevention first reported the nationwide outbreak Thursday, which includes 372 people in 47 states.
The CDC says people reported obtaining live baby poultry, e.g., chicks and ducklings from several sources, including feed supply stores, websites, hatcheries, and relatives. Chicks, ducklings, and other live poultry that look healthy and clean can carry salmonella bacteria, which is contagious and can cause serious illness. Children under five, adults over 65, and people with weakened immune systems are most likely to get sick from salmonella and should avoid handling live poultry.
Always wash hands thoroughly with soap and water after touching live poultry or anything in the area where birds live and roam.
