A North Carolina gastroenteritis outbreak that was traced to tempeh contaminated with a rare Salmonella strain resulted in 89 reported cases, including 8 patients who were hospitalized.
Researchers writing in the journal Emerging Infectious Diseases said the implicated pathogen, Salmonella enterica serovar Paratyphi B variant L(+) tartrate(+), had a DNA fingerprint pattern that previously had not been reported to the Centers for Disease Control and Prevention’s national database of enteric pathogen strains.
