Nationally, 2017 had more salmonella cases linked to backyard poultry than ever recorded by the US Centers for Disease Control and Prevention.
In Washington, 23 cases associated with the outbreak were reported to state health officials. That's more than double the number of cases of salmonella associated with backyard poultry outbreaks in the previous two years combined.
Salmonella can cause serious illness. You can get the infection from a variety of sources, including eating contaminated food or drinking water, touching infected animals and not washing your hands. While anyone can get a salmonella infection, children are especially at risk of illness because they are less likely to wash their hands and have more frequent hand-to-mouth contact than adults.
