U.S. Centers for Disease Control and Prevention has announced that they are currently investigating a national outbreak of Salmonella Montevideo. Illnesses have been seen in 38 states and DNA analysis on the pathogen is underway to confirm whether all of the illnesses are connected to a common source (nothing has been identified yet). Illnesses associated with this outbreak go back as far as July 2009 (with the most recent illness reported on January 1 of this year).

CDC is collaborating with public health officials in many states, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS), and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella serotype Montevideo infections. Investigators are using DNA analysis of Salmonella bacteria obtained through diagnostic testing to identify cases of illness that may be part of this outbreak.

As of 12:00 pm EST on January 22, 2010, a total of 184 individuals infected with a matching strain of Salmonella Montevideo have been reported from 38 states since July 1, 2009.  The number of ill persons identified in each state with this strain is as follows:  AL (2), AZ (5), CA (30), CO (2), CT (4), DE (2), FL (2), GA (3), IA (1),  IL (11), IN (3), KS (3), LA (1), MA (12), MD (1), ME (1), MI (1), MN (4), NC (9), ND (1), NE (1), NH (1), NJ (7), NY (15), OH (9), OK (1), OR (8), PA (3),  RI (2), SC (1), SD (3), TN (3), TX (7), UT (7), VA (1), WA (14), WV (1), and WY (2). Because this is a commonly occurring strain, public health investigators may determine that some of the illnesses are not part of this outbreak.
