Investigation of Outbreak of Human Infections Caused by Salmonella I 4,[5],12:i:-

CDC is collaborating with public health officials in multiple states across the United States and with the U.S. Department of Agriculture’s Food Safety and Inspection Service to investigate an ongoing multi-state outbreak of Salmonella I 4,[5],12:i:- (pronounced “four five twelve eye minus”) infections in humans. An investigation that used interviews comparing foods eaten by ill and well persons is showing that eating Banquet brand pot pies produced by the ConAgra Foods company is the likely source of the illness.

Between January 1, 2007 and October 29, 2007, at least 272 isolates of Salmonella I 4,[5],12:i:- with an indistinguishable genetic fingerprint have been collected from ill persons in 35 states.

Their ages range from <1 to 89 years with a median age of 18 years; 51% of ill persons are female. At least 65 people have been hospitalized.
