CDC investigates salmonella outbreak across 42 states

Nearly 400 people across 42 states have been made sick by a foodborne salmonella outbreak that started back in September, according to the latest update from the Centers for Disease Control and Prevention. The CDC is working with state public health officials to identify the source of the outbreak, caused by the strain Salmonella Typhimurium, and notes that the infection may be particularly worrisome in infants, the elderly, and immunocompromised patients, as these groups face increased risk for severe illness.

California (55), Ohio (53), Massachusetts (39), Minnesota (30), and Michigan (20) have reported the most cases, and 1-12 incidents have been reported in 37 other states. Eighteen percent of the patients nationwide have been hospitalized for the illness.

Over the weekend, a food distributor recalled peanut butter sold under the brands King Nut and Parnell's Pride after salmonella was discovered in an open tub of King Nut in a Minnesota nursing facility. However, it was unclear whether peanut butter was connected to the nationwide outbreak.

We reported last year on salmonella outbreaks involving cantaloupes, and our Safety bloggers have taken a close look at the cases surrounding tomatoes and peppers.
