WFAA reports that at least four people, including three children, become seriously ill after drinking raw milk, according to state health officials.

Mary Chiles, a 57-year-old resident of Dallas, was quoted as saying, "They said it would be a while before I got my strength back.”

Chiles said she tried the milk after a health-conscious friend told her the all-natural, unpasteurized beverage might improve her health.

State investigators have now blocked Lavon Farms in Plano, where Chiles purchased her carton, from selling raw milk until tests are complete.

Owner Todd Moore told News 8 the farm sold thousands of gallons of raw milk and never received complaints of any illness.

It wasn’t clear from initial media reports when the illnesses occurred.
