One person in New York state has been diagnosed with RB51, and that illness was confirmed by the Centers for Disease Control and Prevention. The notice did not state whether or not that person has consumed raw milk dairy products from Miller’s Biodiversity Farm, although the New York Post stated that there is a possible connection. This bacteria does not cause any symptoms in cattle, but is spread from cattle to people.

There can be serious complications from this illness, which include endocarditis, meningitis, and osteoporosis myelitis. The incubation period can be long and last for weeks or months. Treatment is a combination of antibiotics for a long period of time.
