The Ohio Department of Agriculture is investigating the legality of herd-share arrangements, which allow consumers to obtain raw milk.
LeeAnne Mizer, a spokeswoman for the agency said there are public health concerns about the growing number of people consuming raw milk products. Ohio outlawed raw milk sales to consumers in 1997. In 2003, the last dairy farm grandfathered into selling unpasteurized milk to individuals gave up its license following a salmonella outbreak.
