This outbreak is caused by Salmonella Paratyphi B variant L(+) tartrate(+) bacteria, formerly known as Salmonella Java.
The illness caused by this bacteria typically includes diarrhea, fever, and abdominal cramps 12-72 hours after an exposure. Salmonella Paratyphi B variant L(+) tartrate(+) does not cause paratyphoid fever, enteric fever, or typhoid fever.
Epidemiologic and laboratory findings indicate that frozen raw tuna is the likely source of the infections.
Most ill people in the outbreak reported eating sushi made with raw tuna in the week before becoming sick.
On July 21, 2015, Osamu Corporation announced two voluntary recalls of frozen yellowfin tuna from one processing plant in Indonesia.
