The Idaho Department of Health and Welfare (DHW) launched an investigation into the increase in illnesses associated with the consumption of raw milk. Since May 19, almost 60 people have been diagnosed.

The DHW reports that at least 45 of the sick people tested positive for campylobacteriosis. The infections are linked to two dairy farms in Idaho, and steps are being taken to identify sources of contamination.

Specifically, the Idaho Division of Public Health is collaborating on the research with the health districts of Panhandle, Southwest, Central, Southeastern Idaho Public Health, South Central Public Health and Eastern Idaho Public Health.

Risks of campylobacteriosis

Pasteurization eliminates almost all the germs present in raw milk, maintaining its nutritional properties. While raw and unpasteurized dairy products can contain bacteria that cause illness, especially in young children, pregnant women, the elderly, and immunocompromised people.

People affected by campylobacteriosis generally recover within a week, although it is warned that those in vulnerable populations could experience more serious consequences.

Common symptoms of campylobacteriosis infection include diarrhea (sometimes bloody), fever, stomach cramps, nausea and/or vomiting. These symptoms usually begin two to five days after exposure.

Anyone who develops symptoms after consuming raw milk or raw dairy products is advised to seek medical attention immediately.

Long term consequences

Campylobacteriosis infections can cause long-term complications in vulnerable populations, including Guillain-Barré syndrome (neuromuscular paralysis), reactive arthritis (chronic joint pain and inflammation), functional intestinal disorders such as irritable bowel syndrome (abdominal pain and persistent diarrhea), and, to a lesser extent, exacerbation of malnutrition and growth retardation in children; Each of these consequences has a higher risk or worse prognosis in the elderly, immunosuppressed, infants, and people with chronic comorbidities.
