Two in Minnesota sickened by contaminated spicy tuna rolls

State health officials are investigating two Salmonella cases involving contaminated raw tuna. The cases are part of a national outbreak linked to spicy tuna rolls.

The Minnesota Department of Health says two adults were sickened at the end of June. One person became ill after eating spicy tuna rolls purchased at a grocery store. The other was sick after eating at a workplace cafeteria. Neither person was hospitalized. Both are said to have recovered.

Epidemiologist Amy Saupe said the frozen tuna product has a shelf life of two years.

"We're concerned that [packages of tuna] are still at retail locations that could be used to make other sushi or tuna products," Saupe said. "Or, it could be something that people have purchased and have sitting in their refrigerators at home."

Saupe says the contaminated tuna isn't packaged under a brand name. But the vacuum-sealed bags can be identified by the lot number 68568 and a label showing that the product was packaged in Indonesia.

Nationwide, more than 50 people have been sickened by the contaminated tuna.
