A total of 93 individuals infected with the outbreak strain of Salmonella Bareilly have been reported from 19 states and the District of Columbia. The number of ill people identified in each state with the outbreak strain is as follows: Alabama (2), Arkansas (1), Connecticut (4), District of Columbia (2), Georgia (4), Illinois (8), Louisiana (2), Maryland (8), Massachusetts (4), Mississippi (1), Missouri (1), New Jersey (6), New York (23), North Carolina (2), Pennsylvania (2), Rhode Island (4), South Carolina (3), Texas (3), Virginia (5), and Wisconsin (8).
Among 93 persons for whom information is available, illness onset dates range from January 28 to March 23, 2012. Ill persons range in age from 4 to 78 years, with a median age of 31. Forty-six percent of patients are female. Among 51 persons with available information, 10 (20%) reported being hospitalized.
State public health officials are interviewing ill persons to obtain information regarding foods they might have eaten and other exposures in the week prior to illness. On initial interviews, many of the ill persons reported consuming sushi, sashimi, or similar foods in a variety of locations in the week before becoming ill. Among 51 ill persons for whom information is available, 35 (69%) reported consuming sushi, sashimi, or similar foods in the week before illness onset. This percentage is higher than expected compared with results from a survey of healthy persons in which 5% of persons reported consuming sushi, sashimi, or ceviche made with raw fish or shellfish in the 7 days before they were interviewed. The investigation into specific types of sushi is ongoing.
