The CDC and state health officials are investigating potential exposures to Brucella strain RB51 in 19 states, connected to consuming raw (unpasteurized) milk from Miller’s Biodiversity Farm in Quarryville, Pennsylvania. One case of RB51 infection (brucellosis) was confirmed in New York in November 2018, and an unknown number of people may have been exposed to RB51 from drinking the milk from this farm. A cow that tested positive for RB51 has been removed from the milking herd.

As of January 22, 2019, investigators have determined that people in 19 states have bought or consumed raw milk from the implicated farm. The states are Alabama, California, Connecticut, Florida, Georgia, Iowa, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, and Virginia.

People who consumed raw milk or raw milk products from this dairy farm since January 2016 may have been exposed and should talk to their doctor. People who are still within six months of the date they last consumed the raw milk are at an increased risk for brucellosis and should receive antibiotics to prevent an infection and symptoms, and should monitor their health for possible symptoms for six months. If symptoms develop, they should see their doctor immediately for testing. People who last drank raw milk from this dairy more than six months ago and have had symptoms of brucellosis – but not been treated – should see their doctor immediately for testing that can determine if they are infected and need antibiotics to prevent long-term health problems caused by brucellosis.

Consumers should discard any leftover or stored raw milk or raw milk products from this dairy farm.
