Foodborne non-typhoidal salmonellosis causes approximately 1 million illnesses annually in the USA. In April 2015, we investigated a multistate outbreak of 65 Salmonella Paratyphi B variant L(+) tartrate(+) infections associated with frozen raw tuna imported from Indonesia, which was consumed sushi. Forty-six (92%) 50 case-patients interviewed ate sushi during week before illness onset, and 44 (98%) 45 who specified containing tuna. Two strains were isolated samples Traceback identified single importer as common source by case-patients; this issued three voluntary recalls sourced one Indonesian processor. Four Weltevreden also linked to outbreak. Whole-genome sequencing useful establishing link between ill people This highlights continuing foodborne risk seafood consumption, importance processing manner that minimises contamination pathogenic microorganisms need ensure foods are safe eat. People at higher for should not consume undercooked animal products, such seafood.
