Washington State health officials are working with state and local partners to investigate several cases and clusters of Salmonella infections that appear to be linked to eating pork. The ongoing investigation of at least 56 cases in eight counties around the state includes food served at a variety of events.

Disease investigators continue to explore several sources from farm to table, and are focused on an apparent link to pork consumption or contamination from raw pork. Salmonellosis, the illness caused by infection with Salmonella, can cause severe and even bloody diarrhea, fever, chills, abdominal discomfort, and vomiting. Serious bloodstream infections may also occur.

As of July 23, the 56 cases include residents of King (44), Snohomish (4), Mason (2), Thurston (2), Pierce (1), Grays Harbor (1), Yakima (1), and Clark (1) counties. Five of the cases were hospitalized; no deaths have been reported. All were infected with the same strain of Salmonella bacteria. The disease investigation shows a potential exposure source for several cases was whole roasted pigs, cooked and served at private events. The source of contamination remains under investigation by state and local health officials and federal partners.
