Persons Infected with the Outbreak Strain of Salmonella Montevideo, United States, by State, as of 04/28/10 at 9:00 pm EST (n=272)

A map of the United States showing the number of people infected with an outbreak strain of Salmonella by state.

As of 9:00 pm EST on April 28, 2010, a total of 272 individuals infected with the outbreak strain of Salmonella Montevideo, which displays either of two closely related pulsed-field gel electrophoresis (PFGE) patterns, have been reported from 44 states and District of Columbia since July 1, 2009. The number of ill persons identified in each state with this strain is as follows: AK (1), AL (2), AZ (9), CA (32), CO (5), CT (5), DC (1), DE (3), FL (7), GA (3), IA (1), ID (4), IL (28), IN (4), KS (5), LA (2), MA (16), MD (1), ME (1), MI (4), MN (7), MO (3), MS (1), NC (11), ND (1), NE (3), NH (2), NJ (9), NM (2), NY (20), OH (9), OK (1), OR (10), PA (7), RI (2), SC (1), SD (4), TN (5), TX (7), UT (9), VA (1), WA (19), WI (1), WV (1), and WY (2). Because the main Salmonella Montevideo outbreak PFGE pattern is commonly occurring in the United States, some of these illnesses are not part of this outbreak.

Salmonella Senftenberg, a different serotype of Salmonella, has been found in food samples from retail and a patient household during this outbreak investigation. PulseNet identified 11 persons who had illness caused by Salmonella Senftenberg with matching PFGE patterns between July 1, 2009 and April 28, 2010. Public health officials have interviewed 9 of the 11 ill persons with this strain of Salmonella Senftenberg and determined that two purchased a recalled salami product during the week before their illness began. These 11 cases are not included in the overall case count reported above.

Among the persons with reported dates available, illnesses began between July 4, 2009 and April 14, 2010. Infected individuals range in age from < 1 year old to 93 years old and the median age is 37 years. Fifty-three percent of patients are male. Among the 203 patients with available information, 52 (26%) were hospitalized. No deaths have been reported.
