Health authorities report that three people have died and another three have been admitted to hospitals due to consuming milkshakes tainted with Listeria bacteria from a Tacoma, Washington restaurant.
According to a statement by the Washington State Department of Health, investigators determined that the outbreak stemmed from improper cleaning of ice cream machines at a Frugals restaurant. The release highlighted that Listeria infection can manifest up to 70 days after consumption, and the implicated machines had been in use until August 7. The six affected individuals were hospitalized between February 27 and July 22. Genetic analysis of the Listeria strain present in the milkshakes confirmed it to be the same strain responsible for the hospitalizations, as confirmed by the health department.
