The Salt Lake Tribune reports that public health and agriculture officials are investigating six cases of salmonella they believe were caused by drinking unpasteurized milk.

Lance Madigan, spokesman for the Utah County Health Department said milk samples are being tested for the bacteria at the state’s public health lab, with results due next week, adding,

"It’s a known issue that unpasteurized milk will carry a lot of different things, including Campylobacter, E. coli and salmonella. We’re investigating other possibilities but that’s the suspicion at the moment."

The sick range in age from a toddler to a 56-year-old.

The milk was bought in Orem and Heber at Real Foods Market, said Madigan. The stores stopped selling the milk last Friday.
