Raw milk outbreak has spread across most of red state — and isn't over yet

Idaho health officials are investigating how nearly 60 people got sick after drinking raw milk in the past two weeks.

The Idaho Department of Health and Welfare announced in a news release on Wednesday that most of the people reported being sick after drinking raw milk from two different milking operations in North Idaho and southern Idaho. The infections were reported starting May 19.

The state health agency didn’t disclose the names of the dairies, but said they are collaborating with health officials “to identify and fix any potential sources of contamination.”

In a statement, Department of Health and Welfare spokesperson AJ McWhorter said the agency didn’t name the milking operations “because this is a potential risk for any raw milk producer.”

“The milking operations are working with public health officials to figure out which patches of milk might be affected and to take steps to remedy the situation,” McWhorter said.

Raw milk isn’t pasteurized, a process that involves heating the milk to kill bacteria — like Campylobacter, E. coli, Listeria and Salmonella — that can be present in raw milk.

So far, 45 of the people who got sick tested positive for campylobacteriosis, a bacterial infection. But officials say not everyone who got sick has been tested, and that more illnesses could be found.

The Idaho Department of Health and Welfare says its public health division is working with local health officials across six of Idaho’s seven regional public health districts to investigate the source of the outbreaks, including Central District Health, Southwest District Health, Eastern Idaho Public Health, Southeastern Idaho Public Health, Panhandle District Health, and South Central Public Health. Officials are investigating to find batches that are potentially concerning and test milk samples.

What are the symptoms of infections linked to raw milk?

Symptoms of infections from bacteria that can be in raw milk include vomiting, diarrhea, abdominal pain, fever and dehydration. Complications can be severe, especially in people at higher risk such as young children, pregnant women, the elderly and people with compromised immune systems.

Health officials encourage people who are feeling symptoms after recently drinking raw milk to seek medical care promptly. To report an illness or get more information, officials encourage people to contact their local public health district.
