The U.S. Centers for Disease Control reports that based on an epidemiological link and results of laboratory testing, CDC has combined the Salmonella Bareilly investigation with an ongoing multistate outbreak investigation of Salmonella serotype Nchanga infections. The two associated PFGE patterns have been grouped together as the outbreak strains.
A total of 200 persons infected with the outbreak strains of Salmonella Bareilly or Salmonella Nchanga have been reported from 21 states and the District of Columbia.
190 persons infected with the outbreak strain of Salmonella Bareilly have been reported from 21 
states and the District of Columbia.
10 persons infected with the outbreak strain of Salmonella Nchanga have been reported from 5 states.
28 ill persons have been hospitalized, and no deaths have been reported.
Collaborative investigation efforts of state, local, and federal public health agencies indicate that a frozen raw yellowfin tuna product, known as Nakaochi Scrape, from Moon Marine USA Corporation is the likely source of this outbreak.
Testing conducted by the Wisconsin Department of Agriculture Trade and Consumer Protection laboratory isolated the outbreak strain of Salmonella Bareilly from one sample of recalled tuna and one sample of a spicy tuna roll made with recalled tuna.
