The U.S. Centers for Disease Control reports a total of 425 persons infected with the outbreak strains of Salmonella Bareilly (410 persons) or Salmonella Nchanga (15 persons) have been reported from 28 states and the District of Columbia, up from 390 a month ago. Of those sickened, 55 persons were hospitalized, and no deaths were reported.

Collaborative investigation efforts of state, local, and federal public health agencies linked this outbreak to a frozen raw yellowfin tuna product, known as Nakaochi Scrape, from Moon Marine USA Corporation.

On May 10, 2012, Moon Fishery (India) Pvt. Ltd., the manufacturer of the frozen yellowfin tuna Nakaochi Scrape, expanded the voluntary recall to include its 22-pound boxes of “Tuna Strips”, Product of India, marked as “AA” or “AAA Grade” because the product has the potential to be contaminated with Salmonella.

This was the first documented outbreak of human salmonellosis linked to raw, scraped tuna product in the United States. This was also the first foodborne outbreak of Salmonella Nchanga reported in the United States. Consumers should not eat the recalled frozen raw yellowfin tuna product, known as Nakaochi Scrape, from Moon Marine USA Corporation, and retailers and food service establishments should not serve it.
