Haaarrvard, are you listening? Letting sick workers serve food is a recipe for barf.

Waukesha County health officials confirmed Monday that norovirus is behind the outbreak of gastrointestinal illness reported by many of the 500 people attending a fund-raising luncheon last week at the Country Springs Hotel.

Julianne Klimetz, a county spokeswoman, said initial lab results confirmed the cause. In addition, investigators have confirmed that two people handling the food were ill at the time.

Klimetz said the Country Springs kitchen has been cleaned and kitchen staff have been informed about proper hand washing.

Everyone’s a comedian. Did anyone tell the staff not to work if they are barfing? Or would staff get fired for not showing up, even though the no-work-when-barfing thing is written in a manual somewhere.
