2014 Listeria Outbreak Linked to Unpasteurized Milk from Pennsylvania’s Organic Farm

Cow-Listeria Outbreak

The Centers for Disease Control and Prevention (CDC) and regulatory officials investigating found that a deadly outbreak in 2014 seems to be linked to unpasteurized raw milk produced by Miller’s Organic Farm in Bird-In-Hand, Pennsylvania.

Listeria is a dangerous bacteria that can cause a serious, life-threatening illness.

The U.S. Food and Drug Administration (FDA) informed CDC that genome sequencing of listeria bacteria from raw chocolate milk produced by Miller’s Organic Farm showed that it was closely related genetically to listeria bacteria from the two ill people in California and Florida. The ill person in Florida was died later.

CDC recommends that people to use pasteurized dairy products, including soft cheese, ice cream, and yogurt. The health agency warned that unpasteurized raw milk can carry dangerous bacteria such as Listeria, Salmonella, E. coli, and Campylobacter.

“Pasteurization is the process of heating milk to a high enough temperature for a long enough time to kill dangerous bacteria.”

Because listeria was found in raw milk produced by Miller’s Organic Farm, CDC is concerned that conditions may exist at the farm that may cause further contamination of raw milk and raw dairy products distributed by this company and make people sick.
