2015 Outbreak of Salmonella Paratyphi and Salmonella Weltevreden Infections Linked to Frozen Raw Tuna

In the spring of 2015 health officials investigated an outbreak of Salmonella Paratyphi B variant L(+) tartrate (+) and Salmonella Weltevreden suspected of being linked to consumption of tuna used in spicy tuna rolls and other sushi. A total of 65 persons were reported by 11 states. Most of the ill people were reported from the southwestern U.S. or reported travel to this part of the country in the week before they became ill. Illness onset dates ranged from March 5, 2015 to July 20, 2015. Eleven people had been hospitalized. No deaths were reported. The investigation was assigned ID# 1504CAJKX-1. The Minnesota Department of Health and Minnesota Department of Agriculture isolated the outbreak strain from samples of unopened frozen raw tuna collected from a Minnesota grocery store where an ill person in this outbreak reported eating tuna sushi. The contaminated frozen raw tuna collected from the store was imported from Indonesia. As a result of this investigation Osamu Corporation announced two recalls of frozen yellowfin tuna.
