The Salmonella Shrimp Outbreak
As of June 25, 2021, six people infected with the outbreak strain of Salmonella Weltevreden have been reported from two states – Arizona and Nevada (see map). Illnesses started on dates ranging from February 26, 2021, to April 25, 2021 (see timeline).
Sick people range in age from 30 to 80 years, with a median age of 56 years, and 66% are female. Of five people with information available, two have been hospitalized. No deaths have been reported.
The true number of sick people in an outbreak is likely much higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because many people recover without medical care and are not tested for Salmonella. In addition, recent illnesses may not yet be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak.
