Salmonella outbreak linked to raw tuna sushi – update

| July 28, 2015

sushiThe US Centers for Disease Control and Prevention (CDC) is continuing to investigate an outbreak of Salmonella Paratyphi B variant L(+) tartrate(+) – previously known as Salmonella Java – infections linked to raw tuna consumption.

As of 20 July, at least 62 people in 11 states had been affected by the outbreak, with 11 cases needing hospital treatment. Most of those affected reported eating sushi made with raw tuna in the week before they became sick. Other epidemiological evidence and laboratory findings have confirmed that frozen raw tuna is the likely source.

On 21 July, Osamu Corporation, of Gardena California, issued two voluntary recalls for frozen tuna sourced from a processing plant in Indonesia. The first included all frozen tuna sold to restaurants and retail outlets throughout the USA from 9 May 2014 to 9 July 2015, while the second referred to a single lot of frozen yellowfin tuna chunk meat distributed to AFC Corporation for use in sushi franchises in grocery stores nationwide from 20 May to 26 May this year.

Restaurants and retailers have been warned not to sell or serve any of the recalled tuna and vulnerable consumers are advised not to eat any raw seafood products.
