I have spent time sitting across the table from people whose lives were turned upside down after just one meal. Some of those conversations have stayed with me.
The topic of raw milk and Guillain-Barré syndrome is near the top of the list. Because it comes with complications that most people have never heard of, caused by bacteria that most people can’t pronounce, and delivered by products that claim that the entire exercise is a health food.
Let me make clear what I have been saying for the past 20 years: in court, in legislative hearings, and on this blog. Raw milk can put you in a wheelchair.
Campylobacter is the most common cause of bacterial gastroenteritis in developed countries, and unpasteurized raw milk is one of Campylobacter’s favorite vectors. For most people, an infection means a miserable week of cramps, fever and diarrhea. However, in a few unlucky cases, the immune system triggers the body’s nerves as it tries to fight off the bacteria. The result is Guillain-Barre syndrome, an ascending paralysis that can travel from the feet to the lungs in a matter of days. GBS is a rare but well-documented result of Campylobacter infection. It’s not exotic. It’s in the medical literature.
The cruelest part is that contaminated crude oil gives no warning at all. It doesn’t look spoiled. It doesn’t smell. There is no way for a consumer standing at a farm stand or cattle share pick-up area to know whether the jug in their hand contains pathogens. You are literally taking it on faith.
In June 2008, Campylobacter jejuni in raw milk from the Alexandre EcoDairy Farm in Del Norte County, California, infected 16 people. Milk was distributed through the “cow rental” system. This is a type of legal workaround that allows dairies to sell raw milk while pretending otherwise.
One of those sixteen was a woman named Mari Tardiff. Marie developed flu-like symptoms within a few days of drinking the milk. Then her vision became blurry. Then her hands became numb. When doctors discovered the words “Guillain-Barre,” her legs burned with pain that only a hot towel could touch. She woke up one night unable to move. Her husband had to lift her. She was taken to the intensive care unit, intubated and placed on a ventilator. She was in the hospital for two and a half months.
Marie returned home to her family room, which had been converted into a hospital ward. It was equipped with a hospital bed, Heuer lift, standing frame, portable toilet, remodeled bathroom, and 24-hour nursing care paid for by the family out of pocket. She fought through treatment, ultimately unable to bear witness to how much her husband had hurt her. She never walked normally again. She lost the plans she had made for her life.
This is what a glass of “natural,” “alive,” “nutritious” raw milk did for one healthy woman.
If Marie’s story had been a strange incident, she might not have continued to tell it. That’s not true.
In 2012, a 67-year-old man named Jim Orchard drank raw milk from Pasture Maid Creamery in New Castle, Pennsylvania. He, his wife and his daughter were among about 10 people who became ill. All recovered except Jim, who suffered from Guillain-Barre syndrome and ended up paralyzed in intensive care at UPMC Presbyterian. His wife told reporters that at GBS, no one can give the family a schedule because everyone is different.
Here are the details that will make any regulator’s stomach turn. State officials had already warned the public in February 2009 to throw away Pasture Maid’s milk because it contained campylobacter. Three years later, same farm, same bugs, and a man on a respirator. The warning was there. The system simply allowed it to happen again.
People sometimes treat these cases as cautionary tales from less cautious times. That’s not true. In 2010 and 2011 alone, at least nine crude oil outbreaks occurred in a multi-state cluster spanning Washington, Utah, Nevada, New York, Pennsylvania, and Michigan, Indiana, and Illinois. More than 50 cases of illness linked to E. coli O157:H7, Salmonella and Campylobacter have been identified, and at least one Pennsylvania victim was hospitalized with GBS. And last November, Illinois public health officials reported 11 cases of Campylobacter infections linked to raw milk, but did not identify a common cause.
Then look at Idaho, which has become a case study for everything I’m about to ask. Last summer, Campylobacter tied to one dairy product sickened 18 people. By the end of November, the state had reported at least 23 cases of Campylobacter among people drinking raw milk, six of them in children under 12, and three cases of Shiga toxin-producing E. coli infections, which producers did not identify. And just a few days ago, in early June 2026, Idaho announced two more outbreaks. Since mid-May, nearly 60 people have been sick, at least 45 of them confirmed to be Campylobacter, and eight have been hospitalized. Two milking operations – one in the northern part of the state and one in the southern part.
The state declined to name the two dairies. A Department of Health spokesperson explained that the operation was not named because the risks were “potential for all raw milk producers”. Read it again. The agency’s justification for remaining silent is that the risk is not limited to one farm but is inherent in the product. This is not an argument for protecting dairy names. That’s the best argument I’ve ever heard for not drinking raw milk in the first place.
And California, the state that gave us Mari Tardiff, provided us with the greatest example. Beginning in the fall of 2023, raw milk and cream from Raw Farm, LLC of Fresno, formerly known as Organic Pastures, was linked to a Salmonella Typhimurium outbreak, which whole genome sequencing eventually linked to at least 165 illnesses in four states. Health officials called the outbreak the largest raw milk salmonella outbreak in the United States in a decade. Some of these patients also had Campylobacter or E. coli in addition to Salmonella. This wasn’t my first time at Raw Farm, nor was it my 10th. The same work has been linked to post-outbreak and recall after recall dating back to 2006. And here’s the part that might sound familiar. After announcing a small number of cases in San Diego in October, state and local officials remained quiet even as the confirmed number topped 165. The public learned the true extent because the records were obtained and given to The Associated Press. I don’t have to be the one to tell my community how many of my neighbors are addicted.
We’re still having this conversation. We are still seeing people getting sick. Among them are children. And too often we watch institutions remain silent about where their milk comes from, as if the name of the dairy product is a trade secret more valuable than the public’s right to protect itself.
I am not asking anyone to ban their farms or put dairy farmers in jail. I’ve spent my career suing companies, and I’d rather they not give me a reason.
I ask for three things that I have asked many times before:
First, tell the truth on the label. When I urged Wisconsin to reject its raw milk bill a few years ago, I argued that all raw milk sold should carry a blunt warning that it is at least unpasteurized and may contain E. coli O157:H7, Campylobacter, Listeria and Salmonella, infections that can mean hemolytic uremic syndrome, Guillain-Barre syndrome, reactive arthritis, miscarriage or death, and pose the greatest risk to children, pregnant women, the elderly and the elderly. Have low immunity. Consumers deserve to make informed choices. They can’t do that in the dark.
Second, if an outbreak occurs, identify the source. fast. Silence does not protect the public. Protects the accused.
Thirdly, this is the simplest way. The milk is pasteurized. Pasteurization is not a corporate conspiracy. Transforming a high-risk product into a safe product without meaningfully changing what’s in the glass is a 150-year public health victory. Why should raw milk be held to a lower standard than a hamburger, peanut butter, or bag of spinach? You shouldn’t do that.
I understand the appeal of food that feels close to the land. I have nothing against farmers or family dairies. But Mari Tardiff believed her milk was pure. So did Jim Orchard. The trust did not put them in intensive care.
Drink pasteurized milk. Not using a ventilator is the easiest decision.
