A 10-month-old baby in Tennessee developed a life-threatening condition last year and spent 27 days in the hospital with failing kidneys after drinking raw milk from a cow-share, health officials in Tennessee reported Thursday.

At least five people were sickened by raw milk from the cow-share, including another 10-month-old baby who was hospitalized for a day.

The direct sale of raw milk is illegal in Tennessee due to the danger that the unpasteurized dairy product can easily contain deadly pathogens shed from cattle. Yet people get around the law via cow- or herd-shares, in which they purchase a share of an animal or herd and can use milk from the animals for personal use.
