State public health officials have issued a warning on Tuesday stating that consuming raw milk can have potential dangers.

The warning came after the officials noted that nearly six Northern California residents were diagnosed with campylobacteriosis, a bacterial infection that can be caused by consuming contaminated raw milk.

Department officials said a recent identified multiple bottles of Claravale Farm raw milk that tested positive for campylobacter.

Symptoms of campylobacteriosis include diarrhea, abdominal cramps, and fever, said experts. Most people recover completely within about a week but it may vary in some cases, they said.

The infection in some cases can also affect the immune system of young children, and elderly, and can also cause a serious, life-threatening infection. The people with weak immune systems can have severe reactions to illness.

On Sunday, a statewide recall was issued for raw milk, raw nonfat milk and raw cream from Claravale Farm in San Benito County after samples tested positive for campylobacter.

Public health officials also issued warning stating that products with code dates of March 28 or earlier should be thrown away.

As per experts, raw milk is milk from cows, sheep, goats or other animals that has not been pasteurized to kill harmful germs. Contaminated raw milk doesn't smell or look any different from uncontaminated raw milk.

Health officials said they do not recommend drinking raw milk or raw milk products. The sale of raw milk from some dairies is legal statewide, but products must carry warning labels about possible disease-causing organisms, they added.

In the past decade nationwide, the consumption of raw milk has led to outbreaks including campylobacter, E. coli and salmonella, many involving young children, according to public health officials.
