Case Count Update
A total of 100 individuals infected with the outbreak strain of Salmonella Bareilly have been reported from 19 states and the District of Columbia. The 7 new cases are from Connecticut (1), Illinois (1), Maryland (2), New Jersey (1), Pennsylvania (1), and Wisconsin (1).
Among 100 persons for whom information is available, illness onset dates range from January 28 to March 25, 2012. Ill persons range in age from 4 to 78 years, with a median age of 31. Forty-seven percent of patients are female. Among 51 persons with available information, 10 (20%) reported being hospitalized. No deaths have been reported.
Illnesses that occurred after March 8, 2012, might not be reported yet due to the time it takes between when a person becomes ill and when the illness is reported.
Initial Announcement
CDC is collaborating with public health officials in many states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella serotype Bareilly infections. Salmonella Bareilly is an unusual serotype of Salmonella. Public health investigators used DNA "fingerprints" of Salmonella bacteria obtained through diagnostic testing with pulsed-field gel electrophoresis, or PFGE, to identify cases of illness that may be part of this outbreak. They used data from PulseNet, the national subtyping network made up of state and local public health laboratories and federal food regulatory laboratories that performs molecular surveillance of foodborne infections...
