Central District Health is investigating nine cases of illness related to unpasteurized milk, all likely stemming from a Caldwell dairy.

A Thursday morning press release states that nine Ada County residents are fighting foodborne illnesses after consuming raw milk. Two children are hospitalized.

The children have confirmed cases of hemolytic uremic syndrome, a rare complication of E. coli that can result in kidney failure and other long-term health problems.

Several of these Ada County cases have been confirmed as Shiga toxin–producing E. coli, also known as STEC. According to CDH, symptoms of STEC include bloody diarrhea and vomiting. Older adults, children and people with weakened immune systems are particularly vulnerable.

CDH’s investigation is ongoing. The health district is continuing its investigation by interviewing affected individuals and testing raw milk. However, it appears that all cases are linked to raw milk from R Bar H dairy in Caldwell.

According to the release, R Bar H has pulled all of its products from shelves and voluntarily suspended production.

“While CDH waits for the results of testing, out of an abundance of caution, consumers who have purchased these products should avoid consumption and discard any remaining product,” the release states.

The health district advises that anyone experiencing severe stomach cramps, diarrhea or vomiting after drinking raw milk should report their illness and seek medical care.

Raw milk, or unpasteurized milk, is milk that has not undergone pasteurization to kill harmful germs utilizing heat. This includes E. coli, Listeria and Salmonella.

In Idaho, raw milk can be sold legally through multiple outlets according to the Idaho Department of Health and Welfare, but it is not required to be tested for disease-causing bacteria including E. coli.

“While consuming raw milk is a personal choice, health officials urge residents to understand the serious health risks, particularly for young children, pregnant women, and other vulnerable individuals,” the CDH release states.

Those who choose to consume raw milk are advised to refrigerate it within half an hour of purchase and keep it at 32-36 degrees Fahrenheit to prevent bacterial growth. Milk should be discarded if it shows any signs of spoilage including changes in smell, texture and taste. Consumers should also wash their hands before handling raw milk and avoid splatters that could contaminate nearby surfaces.
