Pasteurization is right up there with

What is pasteurization?
Named for French scientist
There are a few different methods, but all involve the milk being heated to specific temperatures and held there for a predetermined period of time, which has been calculated as sufficient to kill the bacteria, like
You may also have seen products labeled as “UHT”, which stands for ultra-heat treated. This is a more extreme form of pasteurization involving higher temperatures and sterile packaging, allowing these kinds of products to be stored out of the fridge for months at a time.
Milk is not the only foodstuff that gets pasteurized. Other examples of foods that can be heat-treated include fruit juices, flour, and Pasteur’s original research subject, alcoholic beverages.
Why do some people drink raw milk?
Almost as soon as pasteurization became standard practice, the controversy began. According to the
Over the decades, many claims have been made about the supposed benefits of unpasteurized dairy products. Here are a few of them.
“It tastes better.”
Some people simply say they prefer the flavor of raw milk. There are also some artisanal
This is one that’s difficult to disprove with scientific research. Suffice it to say, even if you do think it tastes a bit better, most would agree the risks of raw milk (see below) significantly outweigh this.
“It’s easier to digest.”
Some have claimed that treating milk with heat to kill the bad bacteria has a knock-on effect of killing probiotic organisms that secrete lactase, the enzyme that breaks down lactose and that those with lactose intolerance are lacking.
There is no scientific evidence to back up this claim. Raw milk
“It’s healthier.”
Some suggest that the pasteurization process negatively affects the nutritional profile of the milk by degrading nutrients like calcium, essential for healthy bone development. There have also been
Much of this is also tied in with wider skepticism around consuming processed foods, or supposedly “unnatural” products.
The evidence suggests that pasteurization
There is
“It’s fine as long as it’s tested/organic/from a clean farm.”
Some believe that as long as they trust the farm where their raw milk comes from, it is safe to consume.
However, in reality, there is
What are the risks of drinking raw milk?
As well as citing evidence that largely debunks the claims made by the anti-pasteurization league, health authorities like the US Food and Drug Administration (FDA) have
The most obvious, and the reason pasteurization was adopted in the first place, is the risk of foodborne illness.
The
Infection with any of these species could see you saddled with days of diarrheal misery, but there are some potentially serious consequences too, particularly for those who may be more vulnerable such as children and pregnant people. It’s not unheard of for humans to contract
It’s because of these risks that raw milk is illegal to purchase in several US states, and
The verdict? Pasteurized milk is much safer and no less healthy
In a world where some people genuinely debate the utility of
If only there were an easy way to drastically reduce all the risks…
