Authorities in Arizona and New Mexico are investigating a total of 15 Salmonella Paratyphi infections that are suspected of being caused by eating raw fish, and similar cases are under investigation in other states, according to state and local health agencies.
In Phoenix, the Maricopa County Health Department said on May 15 it was investigating nine cases of a rare strain of Salmonella Paratyphi associated with raw minced or ground tuna in sushi. The patients, three of whom were hospitalized, fell ill between Apr 3 and 16.
Bob England, MD, director of the health department, said the cases are linked to multiple restaurants, suggesting that the tuna was contaminated before it reached the restaurants.
In New Mexico, six Salmonella Paratyphi infections are suspected of being caused by eating raw fish, the New Mexico Department of Health (NMDH) reported in a May 15 announcement.
