Officials in the Green Mountain State have confirmed a handful of additional cases of illness related to E. coli. The Vermont Department of Health announced earlier this week that seven-people became subject to the food-borne illness at a South Roylaton eatery called Worthy Burger, though that number has since increased to nine.
State and federal investigations into the outbreak led the restaurant to switch beef suppliers after it was believed undercooked ground beef from a Vermont slaughterhouse could be to blame.
Health officials say Vermont typically sees anywhere between 15 and 25 confirmed cases of E. coli per year, so to have nine cases in a single month was considered alarming. W
orthy Burger voluntarily shut down for five days to address concerns before re-opening to the public September 22.
