Why certified organic milk brands such as Horizon and Organic Valley are toxic despite glowing marketing claims, which falsely lead consumers to believe this type of milk is a healthier alternative to regular supermarket milk.

Fact: Organic milk companies such as Horizon and Organic Valley are pulling the wool over the eyes of consumers.
By marketing their ultrapasteurized (UHT) milk as certified USDA Organic, a willing consumer base buys it, thinking it is a better choice than regular pasteurized supermarket milk.
The sad truth is that ultrapasteurized (UHT) organic milk is just as unhealthy as regular, pasteurized store milk.
I’ve often thought if I HAD to choose between them, which milk would I select as being better: regular pasteurized supermarket milk or ultrapasteurized certified organic milk? That’s a toughie. Neither choice is optimal as there is no clear winner.
Both are highly processed milks, and both contribute to poor health and chronic illness in general.
Pasteurized vs Ultrapasteurized Milk
Let’s first consider regular supermarket milk.
The dairy cows producing this type of milk are injected with hormones and other drugs.
They consume unnatural, GMO, pesticide, and antibiotic-laced feed with no access to fresh air or green grass.
To add insult to injury, these abused animals stand on cement floors their entire lives. No surprise that they usually die within about 18 months. Incidentally, the true lifespan for a healthy dairy cow should approach 15 years.
Milk from confined cows NEEDS to be pasteurized. It is dirty, nasty stuff loaded with pus and pathogens because of the filth and chronic mastitis the cows endure.
Now let’s consider certified organic (UHT) milk. A consumer with only partial knowledge of how milk is processed is easily lured into buying this milk.
On the surface, it seems so much healthier.
After all, the cows don’t get any antibiotics, steroids, or hormones, right?
It’s certified USDA Organic. Doesn’t that mean something?
While the cows producing organic milk may not be subjected to the drugs and antibiotics used on conventional dairy operations, the milk coming from the Organic Industrial Complex is even more highly processed.
For example, ultrapasteurized (UHT) organic milk is subjected to the insanely high temperature of 275–302°F/ 135–150°C for 1–10 seconds (most commonly 2–5 seconds).
This is waaaay over the boiling point!
For reference, the boiling point of milk is 212.4–212.9°F/ 100.2–100.5°C.
Excessively high UHT processing, far above the boiling point, results in a destroyed product (it isn’t really even food anymore), but dairy corporations love it because it has a much extended shelf life compared to regular pasteurization.
The dirty little secret is that certified organic UHT milk can actually remain unrefrigerated for up to 6 months when packaged in aseptic cartons!
Yet, it is placed in the refrigerated section nonetheless because US consumers won’t readily buy cartons of milk from an unrefrigerated shelf. It goes against intuition and just doesn’t seem very natural, does it?
I don’t know about you, but I find this practice outrageous!
To show the disconnect, consider that Moms often buy individually sized aseptic packages of organically certified milk and put them in their children’s lunchboxes….with ice packs that aren’t even needed!
If they only knew that this milk is so dead that it doesn’t require refrigeration, then they might rethink their choice of beverage.
Auto-Immune Disorders
Why is ultrapasteurization so bad?
The high temperature (far above boiling point) necessary to ultrapasteurize organic milk greatly damages the fragile milk proteins. The same thing happens when sweetened condensed milk is manufactured too.
This violent industrial process results in a “food” that the body no longer recognizes when it is consumed.
The enzymes produced during digestion do not “fit together” like puzzle pieces with the milk proteins destroyed by UHT processing.
These undigested proteins then make their way into the bloodstream due to “leaky gut” syndrome, which nearly all Westerners suffer from to some degree.
At that point, the body identifies them as foreign proteins and mounts an immune response.
This translates into symptoms such as allergies, asthma, eczema, reflux, bloating, and other symptoms of autoimmunity.
People who drink this type of certified organic milk often think they have a “milk allergy”. In reality, they have an allergy to the processing, not the milk itself!
Ultrapasteurized milk is so completely sterilized that sometimes it is difficult to culture into homemade kefir or 24 hour yogurt.
In short, ultrapasteurized milk is dead, dead, DEAD.
There is no way that it can be considered healthy, even if it is labeled USDA organic and comes from grassfed cows.
I remember when my first child was nursing, I drank a lot of Organic Valley ultrapasteurized milk.
My baby spit up so badly during that time that there was some concern that he had a reflux disorder.
Remarkably (but not surprisingly), when I stopped drinking the Organic Valley milk, his reflux problem completely resolved. No treatment was required.
I have no doubt that if I had continued drinking this milk while nursing and he drank it as a toddler, that a likely “milk allergy” would be the result today.
Fortunately, I wised up in time to get off the industrialized poison otherwise known as certified organic milk!
Pick Your Poison
While a consumer may be reducing his/her exposure to antibiotic and pesticide residues by choosing Organic Valley milk, this is by no means a guarantee to less chemical exposure.
Processors of organic milk frequently boil the milk to the required 275–302°F/ 135–150°C after the milk is in the plastic or plastic-lined aseptic carton packaging.
Another method (just as toxic), is to fill the package or jug with sterilized hot milk that has not yet cooled down!
Either of these industrialized processes release high levels of endocrine-disrupting phthalates from the plastic or plastic lining into the milk!
Most everyone now knows never to heat food in a microwave with plastic wrap on top for this very reason.
It’s a shame more people aren’t aware of the tremendous endocrine-disrupting potential of drinking all forms of pasteurized milk, even certified organic that is falsely perceived as safer.
Never Buy Certified Organic Milk from the Store!
As you can see, it is an extremely hard decision to pick which milk is more unhealthy: regular pasteurized store milk or certified organic milk.
It is best not to have to make the decision at all!
Seek out fresh raw grassfed milk straight from the cow (or goat) from a farmer in your local area.
And, if you are fortunate enough to have a source for this truly healthy milk, don’t run out and buy a half-gallon of ultrapasteurized organic milk if you temporarily run out of the fresh-from-the-farm variety.
In those situations, it is best to simply go without.
The risks from consuming certified organic milk even on occasion are simply too enormous to ignore.
Another option is to make healthy milk substitutes like this recipe for coconut milk tonic or homemade sprouted oat milk until the next local dairy delivery.

Thank you Sarah for another helpful article! Would you comment on, or post an article about “low temperature pasteurized milk” which I am now seeing in health food stores? Is it less injurious than the UHT milk you have discussed? I usually buy raw milk from a farmer, but on occasion, I have used the low temp pasteurized milk with no noticeable ill effects. Thank you for your time and consideration.
I posted this article about low temp pasteurized milk awhile back. https://www.thehealthyhomeeconomist.com/low-temp-pasteurized-milk-not-a-good-sub-for-raw-milk/
I am so grateful to you for your brilliant, informative, honest writing! This is very helpful! Thank you, Sarah.
I drank raw milk with both my pregnancies and one spat up a ton, the other did not. It’s a crapshoot
Yes, no doubt that babies are all different in how quickly their digestion develops. The odds of spit up are far lower if Mom is drinking raw milk! And spit up and projectile spit up are two different things entirely at least in my experience. My next two babies never spat up unless I took a bite of pasteurized dairy of some kind.
Thanks for that information. Even though I found out organic UHT milk taste a lot better then store pasteurized milk which has a “funny” taste not present in organic or UHT milk.
I started to buy local milk from Wholefoods that is cream top low pasteurized. I have no reaction to that. But I bought ultra pasteurized Horizon half and half from Costco and drank with coffee. I have to take a ton of benadryl. My throat has swelled, my fingers and face is puffy. I also had no reaction to Boars Head Gouda. Does that make any sense?
Yes Diana, the article DOES say “These cows stand on cement floors their entire lives and usually die within about a year and half. Incidentally, the true lifespan for a healthy dairy cow should approach 15 years.”
