Drinking Raw Milk Is Back. Here Are the 5 Myths Driving It

by

I really did not expect there to be a need to write this in 2026, but here we are: please do not be seduced by the claim that drinking raw milk is a health upgrade.

I understand why the argument sounds attractive. Raw milk is marketed as natural, old-fashioned, nutrient-rich and less processed. In an age of ultra-processed food and institutional distrust, that pitch has obvious emotional power.

But the evidence does not support the sales pitch. The claimed benefits are mostly exaggerated, unproven, or available by much safer means. The risks, meanwhile, are real, documented, and often underplayed.

What am I talking about?

Let’s briefly go back to the basics.

Raw milk is milk that has not been pasteurised, meaning it has not gone through the heat treatment used to kill harmful microorganisms.

This is a process named after French microbiologist Louis Pasteur. He showed that controlled heating could reduce or eliminate harmful microorganisms without fully boiling the liquid. Classic pasteurisation uses heat below boiling point, applied for a defined time. He was initially interested in doing this for wine but this same technique was also applied to milk.

Safe drinkable milk was just one part of a far bigger picture within Pasteur’s scientific career. He is not only regarded as one of the fathers of the germ theory of diseases, but also created vaccines for rabies and anthrax.

Preserving food via heat was not a new idea, the concept was already well known. Preservation by sealing food into glass jars was successfully practised a century earlier by Nicolas Appert who in the 1810s would seal it in and then immerse it into boiling water. A similar approach was soon taken by Peter Durand who realised that he could do the same using the far more cost effective tin cans. By about 1822 tin can production had reached the US.

Fun side fact: Food preserved in tin cans was developed in roughly the 1810s, but it took until 1855 for a guy named Robert Yeates to come up with a can opener. Before that it involved a hammer and a chisel. Ugh!

What was the big deal with what Pasteur did if we were already preserving food on bottles and tins?

The key difference is this – early canning worked before people understood why it worked. What Pasteur did was to explain the biological mechanism and then turned that insight into a far more controlled scientific process.

In the 1810s, Nicolas Appert’s method was basically to heat the food, seal it in a bottle or can, and it keeps. Nobody truly understood why, and there was also no understanding of how much heat was needed so too much heat was often applied.

Yes canning was a huge practical breakthrough, but nobody yet understood microbes. People thought the method worked mainly by excluding air, and at the time many people still believed in ideas like spontaneous generation, where decay could arise naturally from non-living matter.

Louis Pasteur’s contribution in the 1860s changed all that. He showed that spoilage and fermentation were caused by living microorganisms. His approach was to heat the liquid just enough to kill or disable harmful/spoilage microbes and to then seal it up to prevent new microbes from getting in.

That became pasteurisation.

Here is my mini FAQ for Pasteurisation

  • Is pasteurisation a form of cooking? – No, it uses controlled heat to reduce microbes but keeps food mostly unchanged.
  • “Mostly”, so what exactly does that mean for milk? – It means that it is still recognisably milk in taste, nutrition, texture, and behaviour, but it is not identical to raw milk.
  • “Ah ha, so you admit that pasteurisation destroys essential nutrients” – Pasteurisation can slightly reduce some heat-sensitive nutrients, but it does not destroy essential nutrients in the meaningful sense. The important nutrients people drink milk for, especially protein, fat, calcium, phosphorus, and most B vitamins, remain largely intact. The FDA specifically says calcium concentration and bioavailability are not affected by pasteurisation. (The FDA explains all this here).
  • Which nutrients does pasteurisation reduce? – The nutrients most affected are things like vitamin C and some minor heat-sensitive components. But milk is not a major vitamin C food anyway, so losing a little vitamin C from milk does not make raw milk nutritionally superior in any practical sense

The very big win is safety.

Raw milk can contain pathogens such as E. coli, Salmonella, Listeria, and Campylobacter, while pasteurisation is designed to kill harmful germs and make milk safer to drink. The CDC says choosing pasteurised milk is the best way to safely get milk’s nutritional benefits, and that raw milk may contain harmful bacteria that can cause food poisoning.

What happens when people drink raw milk?

You don’t need to be psychic to predict what the statistics reveal. By drinking it you are greatly increasing your potential exposure.

From 1998 through 2018, there were 202 reported outbreaks linked to drinking raw milk, causing 2,645 illnesses and 228 hospitalisations. (Link)

Let’s also be clear about something there, that statistic is the documented outbreak count, not the true total. The FDA notes that most foodborne illnesses are not part of recognised outbreaks, and many individual cases are never reported. 

If you drink raw milk already or are considering doing so, then you need to understand the risk you are taking on.

A more risk-based estimate from CDC researchers found that unpasteurised dairy products cause almost all of the roughly 761 outbreak-related illnesses and 22 hospitalisations per year associated with dairy outbreaks from pathogens such as Campylobacter, Salmonella, Shiga-toxin-producing E. coli, and Listeria.

They also estimated that if you are consuming unpasteurised milk and cheese, then you were about 840 times more likely to get an outbreak-related illness and 45 times more likely to be hospitalised than consumers of pasteurised dairy. 

What about now, when raw milk is being politically promoted?

What is striking is that despite the warnings, demand for access to raw milk is increasing.

AP reported April 29 that the push for raw milk is intensifying across the US, with more than 40 bills in 18 states introduced to loosen raw-milk rules. It also says dairy farmers report they can barely keep it in stock, and that influential figures including Robert F. Kennedy Jr have helped boost public interest.

This is having real consequences.

The CDC investigated a 2025 to 2026 E. coli O157:H7 outbreak linked to raw milk cheddar cheese from Raw Farm. The FDA says the outbreak caused nine illnesses in three states, three hospitalisations, and one case of hemolytic uremic syndrome, a serious kidney-related complication. 

Beyond just the normal risks there is now also a new risk – bird flu in dairy cattle. Since 2024, H5N1 bird flu has been found in US dairy cattle.

That should give people pause.

The risk equation is simple: the more people drink raw milk, the more chances there are for outbreaks.

Pasteurisation removes a major route by which milk becomes a vehicle for pathogens. The rising tide of raw milk popularity puts that route back on the table … literally.

The Top 5 Raw Milk Myths

People buy into the idea of drinking raw milk because they have become convinced that it is beneficial and that any risk is minor when compared to the potential benefit.

We need to address this reality, so let’s now review the top 5 arguments that persuade people to do this.

For each of the five I list we need to understand what the claim is, and also how it stacks up against the actual risk.

So here you go then, the top 5 raw milk myths and the facts.

Myth 1. “Raw milk is more natural. Pasteurisation ruins it.”

Why it persuades people:
This argument plugs into a very powerful instinct: “less processed = healthier.” People already distrust ultra-processed foods, so raw milk gets mentally grouped with fresh vegetables, sourdough, local eggs and farm shops.

In the age of ultra-processed food, this argument feels very enticing, but is the claim true?

The Truth:
Pasteurisation is not “industrial junk processing.” It is a short heat treatment designed to kill dangerous pathogens while leaving milk’s core nutrition largely intact. The CDC says pasteurisation is crucial for milk safety and that pasteurised milk still lets people safely enjoy milk’s nutritional benefits. 

The key point is this: raw milk is not healthier in the way an apple is healthier than a packet of crisps. It is the same basic food with a higher pathogen risk. Calling it “natural” does not make E. coli, Campylobacter, Salmonella or Listeria natural things you want in your digestive system.

Think of it this way: Pasteurisation is there to stop milk occasionally becoming a delivery system for kidney failure, miscarriage, sepsis or bloody diarrhoea.

That is the trade-off raw milk advocates often blur. The benefit is speculative. The risk is not.

Myth 2. “Raw milk has better nutrients, enzymes and probiotics.”

Why it persuades people:
This sounds scientific. “Enzymes,” “bioavailable nutrients” and “probiotics” give the claim a health-food gloss. It feels like pasteurisation turns living nutrition into dead nutrition.

The Truth:
The nutrient claim is much weaker than it sounds. Reviews of the evidence find that pasteurisation has minimal effect on milk’s overall nutritive value, especially for the nutrients people mainly drink milk for: protein, calcium, fat, carbohydrates and many minerals. One review found the effect on nutritive value was minimal, though some heat-sensitive vitamins may be affected to a limited extent. 

The enzyme argument is also mostly a red herring. Enzymes in milk are not magic health compounds your body needs intact. Your stomach acid and digestive enzymes break down many dietary enzymes anyway. FDA guidance also rejects the claim that raw milk contains meaningful probiotic organisms in the way raw-milk advocates often suggest. 

Raw milk may contain more microbes, but “more microbes” is not the same as “better probiotics.” A probiotic is a known beneficial organism given in a useful amount. Raw milk is an uncontrolled microbial gamble.

So the honest comparison is not “living superfood versus dead milk.” It is pasteurised milk with nearly the same core nutrition versus raw milk with unpredictable contamination risk.

Myth 3. “Raw milk helps with lactose intolerance.”

Why it persuades people:
This is one of the most attractive claims because it offers a personal miracle: “I could not tolerate milk, then raw milk fixed me.”

Personal anecdotes like this are powerful, but is it actually true?

(Spoiler: No)

The Truth:
This claim has been directly tested. A controlled study in adults with lactose malabsorption found that raw milk did not reduce lactose malabsorption or lactose-intolerance symptoms compared with pasteurised milk. 

The reason is straightforward: raw milk still contains lactose. Pasteurisation does not create lactose intolerance, and raw milk does not remove lactose. If someone feels better on raw milk, other explanations are possible: smaller portions, placebo effect, different fat content, different diet around the same time, or misidentifying the original problem.

If raw milk fixed lactose intolerance, that would be easy to show in a blinded trial. When it was tested, it failed.

For someone with genuine lactose intolerance, the safer options are lactose-free milk, lactase tablets, yoghurt with live cultures, or hard cheeses, not unpasteurised milk.

Myth 4. “Raw milk protects against allergies, asthma and immune problems.”

Why it persuades people:
This is probably the most emotionally persuasive argument, especially for parents. It connects raw milk with the “farm effect”: children raised around farms sometimes have lower rates of allergies and asthma.

The Truth:
There is some observational evidence that children exposed to farm environments have lower allergy rates, and some studies have found associations involving farm milk. But that does not prove raw milk itself is the protective factor. Farm children are exposed to animals, barns, soil, microbes, different diets, different lifestyles and different environments. The milk may be a marker for farm life rather than the cause.

A major review noted that raw milk consumption may have a protective association with allergy development, but that the relationship may be confounded by other farming-related factors. 

The “farm effect” may be real, however, bottling unpasteurised milk is not the same thing as safely recreating a farm childhood.

Even if some immune benefit existed, it would still need to be weighed against actual known harms. Raw milk has been repeatedly linked to outbreaks involving E. coli, Campylobacter, Salmonella, Listeria and other pathogens. The CDC notes that raw milk can cause serious illness, especially in children, older adults, pregnant people and people with weakened immune systems. 

You do not strengthen a child’s immune system by giving pathogens a chance to injure their kidneys.

Myth 5. “Modern raw milk from clean farms is safe enough.”

Why it persuades people:
This is the most reasonable-sounding defence. People imagine dirty Victorian dairies versus today’s inspected farms, stainless steel equipment, testing and refrigeration. They are not entirely wrong that hygiene is better now.

The Truth:
Good hygiene lowers risk, but it does not eliminate it. That is the whole problem. Milk comes from animals. Animals shed pathogens intermittently. Contamination can happen even on farms that look clean and care deeply about standards.

The Food Standards Agency’s position is not “all raw milk is filthy.” It is that even with controls, unpasteurised milk may contain harmful bacteria, and vulnerable groups should not consume it.

That is the killer point: you cannot tell by taste, smell, farm reputation or Instagram aesthetics whether that bottle is one of the risky ones.

“Clean farm” reduces the odds. Pasteurisation changes the game. One is risk management. The other is a kill step.

The Bottom Line

The raw milk pitch works because it combines five attractive ideas: naturalness, superior nutrition, digestive relief, immune benefits and trust in small farms. Those are not foolish concerns. People are right to worry about ultra-processed food, gut health and institutions that do not always deserve blind trust.

But raw milk is the wrong answer to those concerns. Its claimed benefits are exaggerated, unproven, or available by safer means. Its risks are real, documented and sometimes severe.

Raw milk offers speculative benefits and proven risks. Pasteurised milk offers almost the same nutrition with the main danger removed. That is not fearmongering. It is simply a much better trade.
