An outbreak of Salmonella Typhimurium was associated with eating Cub Brand, stuffed chicken products, such as Chicken Kiev, Chicken Broccoli and Cheese, Chicken Mushrooms and Cheddar, Chicken Mushrooms in Wine Sauce, and/or Chicken Romanov. The illnesses developed between April and June. A matching strain of S. Typhimurium was isolated from a stuffed chicken product that had been purchased by one of the case-patients. The case-patients had microwaved the product and did not check the internal temperature prior to eating it. This same brand had been associated with an outbreak of Salmonella Heidelberg in 2005. At that time, the Minnesota Department of Health and United States Department of Agriculture had issued advisories on safe preparation of frozen, chicken products. The warnings were not sufficient to prevent this outbreak.
