Listeria strain not the type that makes people sick
PIERRE, S.D. (AP) - Experts say the listeria strain found in a sample of raw milk sold in South Dakota is not the one that often makes people sick.
The state Agriculture Department on Jan. 21 announced that a sampling of bottled raw milk from Brookings-based Jerseydale Farms tested positive for listeria. The agency cautioned the public that unpasteurized milk bought from the operation might contain harmful bacteria.
Scientists say that the listeria strain found in the milk isn't the one that poses health threats. State public health veterinarian Russ Daly says a different strain is responsible for most listeria infections in people.
The Agriculture Department says it was obligated to inform the public, even though tests of the listeria strain hadn't been completed at the time of the announcement
