The source behind a norovirus outbreak that sickened a few hundred people last year has been identified, according to a report published Thursday by the Centers for Disease Control and Prevention.
The report looked at the outbreak in Tazewell County, Illinois, which includes part of Peoria, which saw 317 people fall ill, all of whom dined at a restaurant — referred to as restaurant A — between Nov. 19, and Nov. 26, 2022.
Investigators with the Tazewell Health Department and Illinois Department of Public Health concluded the outbreak was likely caused by a sick food handler at the restaurant who had ungloved contact with salad, toppings and dressings during food preparation.
