Today the CDC announced that 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. All 200 cases are believed to be linked to sushi made with a raw yellowfin tuna product known as Nakaochi scrape.

190 persons infected with the outbreak strain of Salmonella Bareilly have been reported from 21 states and the District of Columbia. The number of ill persons with the outbreak strain of Salmonella Bareilly identified in each state is as follows: Alabama (2), Arkansas (1), Connecticut (8), District of Columbia (2), Florida (1), Georgia (9), Illinois (15), Louisiana (3), Maryland (20), Massachusetts (24), Mississippi (2), Missouri (4), New Jersey (18), New York (33), North Carolina (3), Pennsylvania (7), Rhode Island (6), South Carolina (3), Texas (4), Virginia (9), Vermont (1), and Wisconsin (15). 10 persons infected with the outbreak strain of Salmonella Nchanga have been reported from 5 states. The number of ill persons with the outbreak strain of Salmonella Nchanga identified in each state is as follows: Georgia (2), New Jersey (1), New York (5), Virginia (1), and Wisconsin (1). 28 ill persons have been hospitalized, and no deaths have been reported.

The CDC’s recent estimates that for every case counted, 29.3 cases go unreported and therefore uncounted. See Table 2 – (http://wwwnc.cdc.gov/eid/article/17/1/p1-1101-t2.htm) in this citation: Scallan E, Hoekstra RM, Angulo FJ, Tauxe RV, Widdowson M-A, Roy SL, et al.

That would mean this outbreak has sickened as many as 5,860 people. If applying a previous CDC estimated ratio of non-reported salmonellosis cases to reported cases (38.6), one would arrive at an estimated 7,720 illnesses from this outbreak. Voetsch, et al.
