The nationwide salmonella outbreak may have killed a person in Minnesota. A health department spokesman in Minnesota says an elderly woman had the infection when she died, but it’s not clear that salmonella was the cause.

The U.S. Centers for Disease Control and Prevention says the outbreak has struck 42 states and made nearly 400 people ill. The CDC has not yet released the list of states or determined which foods may have caused people to become sick (expected in the next few hours). However, health officials in Illinois, North Dakota, Ohio, Georgia, Minnesota and California have confirmed cases. Ohio and California reported the most, with 51 cases each.
