Knox County health officials are warning milk drinkers to be cautious of raw milk.
The health department began investigating E.coli illnesses from drinking raw milk last week.
They warn shoppers not to drink any raw milk or dairy products from McBee Dairy Farm in Mascot. If you have any, they advise you throw it out because of a possible E.coli contamination.
So far, the health department has confirmed three cases of E.coli and is looking into more cases.
