Here’s How to Make Raw Milk Safe (Pasteurization)
HTML-код
- Опубликовано: 7 сен 2024
- A lot of people on the internet have been telling Alex to drink raw milk. This is a bad idea, a particularly bad one actually. So she wanted to make a video about why it’s such a bad idea to consume raw milk then she realized she’s been eating raw milk without even knowing it via cheese. That’s when things got complicated.

Even my great grandma, who was an actual peasant from the Ottoman Empire, used to know that raw milk could make you sick. She didn't even have a formal education of any form. It was ancestral knowledge.
..and on the other side of the pond today, we have these dumbasses with half a braincell promoting to drink this stuff, because it's 'natural' somehow. I understand that you don't trust the milk from the major companies, but at least boil the stuff you bought from wherever before drinking it.
I think the biggest factor in this video that will make most of Europe mad is the lack of temperatures in Celsius.
@@meghankrajchi4913 To think this is a science channel *_representing the actual Chemistry Society_* and it doesn't use SI units tells you all you need to know about the minds of Americans
@@jimurrata6785 Fahrenheit absolutely makes sense to use, especially when dealing with temperatures +/- 100F from room temperature, It is much more practical to conceptualize. Just ask Canadians, they'll tell you "both, fahrenheit in the kitchen, celcius for most every thing else".
I was going to write the same but luckily someone already thought of it. Great video nonetheless.
@@kelseycochrane3103 case in point of americans being incapable of understanding how 95% of the rest of the world have no concept of "+/- 100F from room temperature" as if citing canadians somehow makes the rest of us irrelevant. i have no freaking clue what those fahrenheit numbers mean and i'm not gonna google it.
If she was a real scientist she would use Kelvin :D
Here in Sweden raw milk was referred to as "The White death".
And is strictly prohibited to be sold for consumption.
Your country has much more sense than it did in the Viking era. In terms of both pasteurization and not raiding or pillaging anymore!
@@AngelaWildman-ep6qu yeah, we're quite done with the whole take over the world thing!
Btw if anyone is curious what raw milk tastes like, I tried it once so you don’t have to: it tastes exactly like milk lol
LOL
Been drinking raw milk for over 17 years, including making raw milk cheese
Good video! Just a suggestion: would be nice to see temperatures in Celsius degrees next to Fahrenheit, particularly important because we’re talking about science
Thank you
Here, here! 🌡
Fahrenheit???
Yup butyric acid smells like vomit but is also what gives parmesan its delicious funk. I just think of it like salt, or vinegar. A little can make your dish pop, but a lot will just make want to hurl.
What you said in 1:21 fits me. The video was good but could you please at least put the Temperatures in Degrees Celsius in the subtitles.
Low Temp/Long Time is my favorite Boston song 😂
I had a friend who was kinda obsessed with his DIY mozerella... I think his cheese pH meter was his most prized posession... it takes all types to make a world.
Considering the background of the channel, please also give temperature in celcius :)
Could you use Celsius alongside Fahrenheit temp, please? You are a science-centric channel, after all ;)
Very informative and well presented, thank you.
This is such a fun video! I never had any intention to consume raw milk, but I clicked on the video out of curiosity. I stayed because the vid was just so interesting, charming and funny. Thanks for sharing!
So if they allow selling raw milk they must keep track of how many people get sick. So how many get sick from drinking raw milk every year?
Also they must have some requirements of testing the raw milk if they allow raw milk to be sold. (It is not allowed where i live).
According to a report in 2022..112 people in the USA got sick from raw milk.
I tried raw milk once.
It was the same flavor and texture except you had to shake it.
Turned the rest into yogurt
Uh oh, seems you've summoned some raw milk apologists in the comments. At least they're contributing to engagement metrics. Always fascinating how people can so strongly trust their anecdotes over data. Or how they expect matters of public health to only factor in the individual. I found it pretty funny that the raw milk jug had a "gmo free" label on it. I think that says a thing or two about their target demographic.
But overall a solid overview of this topic. Obviously it won't change the mind of those true believers but I think it's still important so that those they attempt to sway can make an informed decision for themselves. Everyone has their own risk tolerance and if people want to roll the dice when the alternative has little to no downsides, that's their prerogative.
Modern medicine and science has helped to give us the longest life expectancy in history IF you chose to take advantage of what it has to offer. Why go back to the ideas that gave us only a
Well, it’s quite arguable which exact aspects of our knowledge is responsible for the increase in longevity…
In the past week I have consumed 4 litres of raw milk from a closed herd of pedigree Holstein cows near me, and as of now it is my milk of choice. I am big enough and old enough to realise that should I be unlucky it is nobody's fault but mine, in the UK the milk is sold with a health warning displayed on the container. Chilled it tastes very slightly different but not much different to processed milk.
Feta and goat cheese are low acid? Did you maybe mean low pH? They're both obviously known for their tang, so I'd be surprised if the sit higher than other cheeses on the pH scale
@@rfldss89 Taste some sodium hydroxide. 🤔
I guarantee it will be "tangy". 🤣
Buteric acid- why old tools start smelling funky after a while.
That sticky screwdriver handle that stinks up the whole drawer!
Excellent overview. Thank you.
Yeah don't drink raw milk cheese either, you might choke if you try
Hey FYI, the first 4:30-ish of this video lost its captions for some reason!
Thanks for letting us know--it's been fixed!
There were so many important points that I missed even though I listened carefully. So I'll have to watch it five or six more times
Thank you Dr D! Appreciate the sanity here
I didn't expect this to turn cheesy 😋but the recommendations are solid. As are some of the cheese. Well put together too.
To possible confuse the issue a bit, what about cheese with blue stilton?
Looking forward to another cheese pH related video to justify the purchase of the Cheese-o-PH-o-Meter :D
Well that's funny. I was raised for years on raw milk.
Nice video, as always
I am drinking some raw milk right now. Delicious.
How do you feel about indigenous herders who drink raw milk, like the Sami and Mongolians?
someone else commented about how smaller herds can be cleaner, i assume they're no where near as dirty as US dairy cows over there
@@maequackers5397 very true, and even so, it definitely IS still riskier than pasteurization
You think they never got sick?
I need to replay this video in 0.5x
7:26 that's english pronunciation, not french
Some folks really really want to win the Darwin awards Hard!!!
talking about science and using imperial system is crazy.
Thanks
Can people taste any difference?
I have only had Raw milk strate from a cow. And that is both warm and very high in fat. So that tastes very different. 😂
Skip the tutorial needs to watch this
In the state of Texas in state licensed raw milk dairies that the milk and cows are test on a regular basis. Stored at 36f the raw milk lasts longer than the pasteurized milk from the store. We used to have milk from the supermarket go bad in less than a week probably because of bad handling from the store. Sorry we’ll keep drinking milk that we purchase directly from the state licensed raw milk dairy.
For the benefit of the rest of the world &/or anyone in the 21st century, please subtitle frenheit (I can't even spell it)
No one uses Fahrenheit, except for some new-worlders. Please use Celsius? Thank you.
You can thank Al Capone for promoting pasteurized milk.
This was really interesting. The only extra thing I might had is that I remember hearing about drinking raw goat milk to cure kissing disease (Glandular fever). Was common folk knowledge in Israel, I heard Bedouins did that first.
Friends don't let friends eat pasteurized camembert.
I know this might sound crazy but how about not drinking milk?
Because dairy is delicious
@@CampingforCool41 Yes yes tons of unhealthy things are delicious, but we as a society need to make better choices, especially in America
Is raw milk safe for consumption if you drink it on the same day it was milked?
No, it's infected with bacteria inside the cow.
So the bacteria and viruses are "fresher"???
Stop it with... what? Could you repeat that? :P
ok, so raw milk is about 6 times more dangerous on the bacteria side of things. that does not seem too unreasonable.
Safety is super important:
1. Dont EVER drink raw milk.
2. Wear a helmet while brushing your teeth.
3. Never take multivitamins without consulting your doctor.
I mean, that's all well and good but people only started becoming lactose intolerant because of pasteurization. All the enzymes necessary to break down the lactose got broken down during the process and now you might not have a few hundred dead people but you most certainly have a few million lactose intolerant people. Which raw milk could help with. Not saying you'd have to drink it every day and of course you'd have to source it from someplace reputable (just like all other regenerative, sustainable, grass-fed/finished animal products) but to just go based on one specific thing is kind of upsetting but I understand considering this is much larger than just chemistry and this is a chemistry channel.
This is a common claim but not backed by science: www.ncbi.nlm.nih.gov/pmc/articles/PMC3948760/
This isn't true? The body creates the enzyme which breaks down lactose. People with lactose intolerance do not produce it or at least not enough of it. It's actually a mutation to be lactose tolerant as the vast majority of mammals lose the ability to break it down as an adult. You do need to keep ingesting lactose for your body to keep making the protein to break it down (this is why going vegan can cause intolerance for some people), but sometimes, your body just doesn't do it anymore anyway. Such as mine lol
Please preface your comments THIS IS AIMED AT URBAN AMERICANS. "It's a bad idea" depends very much on where you are. It depends on the distribution network, the health of the herd and how long it's to be kept. I dont advocate people seek it out for some magical properties. Pasteurisation also changes the protein/calcium complex because, to coagulate it to make cheese, you have to add calcium chloride.
It does not as locale specific as you think. Milk consumption was avoided historically because of the risks, which is one reason cheeses, butter and yogurt were developed. Another was food preservation.
@belg4mit yes, historically. And there are places in the world today (eg parts of Europe) where limited (usually time/distance) distribution of raw milk does NOT cause significant health risks, partly because of our ability to test cattle and milk for pathogens, which was not possible in times gone bye.
Cheese isn't "raw" milk. The milk is COOKED in the cheese-making process.
Not always. For camembert, the milk is heated to 37°C (human body temperature), and then exposed to a mix of lactic bacteria and rennet (a complex set of enzymes involved in the digestion of milk in ruminant mammals).
I would hardly call that cooked. Using raw milk for camembert makes a noticeable difference in taste.
Yeah, have Oatmilk; all problems solved !
@@dutchyjhome Haha, funny.
The biggest problem there is that oat juice isn't milk.
@@kyokoyumi Well I would consider that to be a plus, since cow milk obviously should not be drank by humans in the first place since the mother cow produces her milk for her calf to be drank. It actually is weird, when you look at this from a distance, that humans drink cow calf milk to begin with, when you think about it... And yes oat drink is no milk, maybe even for the better.
@dutchyjhome Oat juice is unhealthy and laden with plant toxins, such as phytate and oxalate, and is almost always made with industrial seed oils, which have gone through complete lipid peroxidation, making them incredibly toxic to the body. So yes, drinking milk is much better than drinking any so-called "plant milk". There's no such thing.
I agree we shouldn't be consuming milk, but it's miles better than the plant-based crap. If anything, we should be carnivorous like our ancestors; their food was almost entirely meat as the evidence shows.
Internet trends vs common sense
Sorry , we grew up on a dairy farm and lived on raw milk ,butter and cheese made from raw milk , sorry but some of the things that you say is total junk
We take factual accuracy very seriously, so please let us know if you've found any errors!
is this science channel or? for future video can you also add in non-freedom units for 99%+ of the countries on this little planet that cannot read freedom unit.
I reject your reality and substitute my own.
i wont argue with you because most of the time its true however there are ways of getting raw milk that is perfectly save to drink one of the main reasons most milk needs to be pasteurized is because the cows live in very dirty environments and are fed large amounts of grain this among other reasons greatly increases the chance that the milk is dangerous the other main cause is that it is cheaper on the industrial scale to just kills all the bacteria then it is to solve the underling problems
No, there is no way of getting raw milk that is "perfectly safe" to drink. You can decrease the odds you will get sick, but they are always there and they are always, always going to be higher than with pasteurized milk. That's just a fact. You can maybe argue that with the right methods you personally feel the risk is minimized to the point where you can accept it, but that is all.
The udder is just too close to the back end of the cow for it to be bacteria free
@@ginan7712 OR, it could be something like a virus (H5N1) that's endemic to the cow, and she passes it right through.
That's nothing that washing the teats or equipment is going to solve.
@@Tinil0 pasteurized milk is not perfectly safe ether and i don't sell it for a reason i trust my own efforts to remove any problems much more then i trust most company's. it is fine that you don't want to but i know the risks and i know ways to reduce the risk to a level similar to or lower then pasteurized milk. also one point i do want to make is that not only dose it taste much better but it dose allow some not all but some people how cant drink store bought milk drink milk, whether this is because of pasteurization or some other factor i don't know
Drank raw milk over 30 years, never once had had a problem.
Just follow basic cleanliness and farming rules
Seems to be someone is ill informed, dishonest, or spreading misinformation here.
On the other hand, we bought a gallon of milk at a grocery store while on vacation and it was tainted with some kind of cleaning chemicals. Our family and friends got exceedingly sick. Brought it to the attention of the store and local hospitals and of course nothing became of it.
Nice anecdote. I'm still gonna stick with the conclusions of controlled experiments, though.
Ah yes, your single anecdotal experience surely proves the validity of your argument, it far outweighs the other few hundreds of millions of people who drink regular pasteurized milk from the store with no issue on a regular basis.
Instead, we should all make sure that we micromanage our raw milk to ensure it remains tolerably safe for no discernable benefit.
anecdotal evidence, also yeah you can probably drink it when you get it and become immune to the bacteria through exposure but that doesn't apply to most of the population lmao
You are using faulty reasoning. Sure, if you have a perfectly healthy cow and you drink the milk very soon after it comes out of the cow then your odds of getting sick are very low. Of course your odds of getting sick are very low. If drinking milk was likely to make people sick frequently, the cultures that drank milk thousands of years ago would have all died off or quit drinking milk.
Additionally, many people can drink milk that isn't particularly safe and still not get violently ill. Why? Because a healthy immune system will protect them in most cases. But even healthy seeming people can get sick. If you are otherwise healthy but are run down some or are already fighting off something else (possibly without even knowing it), your immune system has less spare capacity to fight off the new invaders. People who are less healthy or are very young have less capacity to begin with so their odds of getting sick are naturally higher. But anyone can: young, old, ill, or healthy.
Pasteurization reduces the number of invaders by a lot. It doesn't eliminate them, but it makes it so that there are far fewer to begin with. What this means is that the immune system needs less spare capacity to fight them off. It also means that it will take longer for the invaders to replicate to levels that would overwhelm most people's immune systems and make them ill. Because they are replicating. While sitting in the fridge. While sitting in your gut. The question is whether or not enough of them exist to invade your body successfully. If you start out with lower numbers, the answer is far more likely to be no. Again, it is often likely to be no because otherwise nobody would've ever drank milk in the first place. But milk isn't the only source of things trying to invade and not everyone has the same number of defenders and so pasteurization is our friend because it, by the numbers from that study, cut the number of invaders down by 600%. If I have to defend a wall, I'd far rather be facing 10 guys than 60 guys, no matter how many others there are defending the wall with me.
That's survivorship bias. You know why all the old buildings we see still standing around 100+ years after construction seem so well-built? Because all the badly built ones already fell down.
We do not have enough study about bacteria culture interacting with large organisms.
"We"
@@ChaohsiangChen Certainly do!
Let's take the current listeria and e-coli outbreaks on store shelves across the United States for example...
@@jimurrata6785
How about let's talk about the bacteria and yeast in your intestines and how those help you break down food in a cooperative manner?
@@ChaohsiangChen Right.... 🙄
But THIS is not that.
Not at all!
@jimurrata6785
It is. Escherichia coli was found naturally in your intestines. It is not something out of nature, such as the strains of spirochetes that came out of US bioweapons lab that caused Lyme disease.
This is a ridiculous and dumb take and unscientific at that. Try again. Raw milk has been used for over 10 000 years, if not longer.
That's why I subscribe spontaneous generation. People living back then really knew how the world worked. Sorry I just read your other comments further down. I'm sorry for being snarky but I feel that that's really the only way to deal with this sort of misinformation. I will not be replying if you respond.
I feel sorry for you and your surroundings
@@Aa.11aaa Alrighty then. I'm helping people around me improve their health, but maybe you don't like that.
@hugoanderkivi
When you accuse scientific research of being "ridiculous dumb unscientific", then it's hard to argue with people like you, also the 10k years the infections were far less than nowadays.
There are a lot of benefits to raw milk.
False
@@A.Filthy.Casual True
Provide a peer reviewed source
source where? they literally quoted and showed a source showing how pasteurised milk is almost exactly the same as raw milk but without the bacteria, what on earth are you looking for lol
@@macslash5833 I think he means OP, mate
Raw milk is fine actually
it is like eating stuff that fell on the floor.. most of the time it is fine.. but take that risk for no benefit?
