California health officials Tuesday warned the public that the consumption of unpasteurized (raw) dairy products may cause serious illness after six Northern California residents have recently been diagnosed with campylobacteriosis, a bacterial infection that can come from consuming contaminated raw milk.

A recent investigation conducted by CDPH identified multiple bottles of Claravale Farm raw milk that tested positive for Campylobacter. Under the direction of the California Department of Food and Agriculture (CDFA), Claravale Farm has initiated a recall of the affected product.

Although the sale of raw milk from some dairies is legal in California, CDPH does not recommend drinking raw milk or raw milk products or giving raw milk, colostrum, raw cream or other raw milk products to children. Raw milk products sold in California are required to carry a warning label:

“WARNING: Raw (unpasteurized) milk and raw milk dairy products may contain disease-causing microorganisms. Persons at highest risk of disease from these organisms include newborns and infants; the elderly; pregnant women; those taking corticosteroids, antibiotics or antacids; and those having chronic illnesses or other conditions that weaken their immunity.”

Campylobacteriosis may cause diarrhea, abdominal pain, fever, nausea, and vomiting within two to five days after exposure to the organism.  Illness can last for up to a week or more and can be especially severe for those who have weakened or compromised immune systems, and for young children and the elderly. Although most people who get campylobacteriosis recover completely, some patients do suffer long-term effects, including arthritis and paralysis.

Raw milk is milk from cows, goats, sheep, or other animals that has not been pasteurized (heat treated) to kill harmful germs. A wide variety of germs that can make people sick have been found in raw milk, such as Brucella, Campylobacter, Listeria, Mycobacterium bovis, Salmonella, and Shiga toxin-producing Escherichia coli, including E. coli O157. E. coli O157 can cause hemolytic uremic syndrome, which is a sometimes deadly cause of anemia and potentially permanent kidney failure. Raw milk contaminated with disease-causing bacteria does not smell or look any different from uncontaminated raw milk, and there is no easy way for the consumer to know whether the raw milk is contaminated.
