MADISON (WKOW) -- State health officials say lab work confirms the recent salmonella outbreak came from recalled yellowfin tuna.
The Wisconsin State Laboratory of Hygiene says DNA found in samples of the tuna matches the strain involved in the outbreak.
The fish was used in sushi and tuna rolls at restaurants and grocery stores.
More than 160 people got sick across the country, including 15 in Wisconsin.
Three of those 15 patients were hospitalized, but they've all recovered.
