Salmonella cases linked to contaminated raw tuna, part of national outbreak

One lot found to contain outbreak strain; retailers should not sell, consumers should not eat

Two Minnesota residents sickened recently with salmonellosis are linked to frozen raw tuna, the Minnesota Department of Health (MDH) said today.

The ill Minnesotans are adults in their 30s from the metro area who became ill on June 21 and June 30. Neither was hospitalized. These cases, which are part of a larger national outbreak (See CDC: Multistate Outbreak of Salmonella), were linked to spicy tuna rolls purchased at a grocery store and a workplace cafeteria. The outbreak strain of Salmonella bacteria was found in sealed bags of frozen raw tuna from the lot used to make the spicy tuna rolls eaten by one of the cases.

The tuna product is packaged in frozen, vacuum-sealed bags without a brand or other name. The contaminated lot of tuna can be identified from labels on the tuna bags (Photo A) and product information on the enclosing box (Photo B) that bear the lot number 68568 and country of origin of Indonesia. The tuna was distributed by Osamu Corporation (Gardena, CA). Retail stores should not sell and consumers should not eat tuna from this lot.

Grocery stores and other retail outlets should check their raw tuna supply for bags or boxes labeled with Lot 68568 from Indonesia (check with your supplier or shipping receipts/invoices if individual bags are not labeled). Tuna from this lot may be contaminated and should be discarded and not sold or served.

Consumers concerned that they may have purchased sushi made with this tuna should contact the place where it was purchased. The investigation in Minnesota and nationally is ongoing.

Symptoms of salmonellosis include diarrhea, abdominal pain and cramps and fever. Symptoms usually begin within 12 to 72 hours after exposure, but can begin up to a week after exposure. Salmonella infections usually resolve in 5 to 7 days, but approximately 28 percent of laboratory-confirmed cases require hospitalization. Invasive infections (e.g., blood stream infections, meningitis) occasionally occur. In rare cases, Salmonella infection can lead to death, particularly in the elderly or those with weakened immune systems.
Approximately 700 cases of salmonellosis are reported each year in Minnesota.

More information on Salmonella and how to prevent it can be found on the MDH Web site at Salmonellosis.
