Why Can’t You Buy Raw Milk in Supermarkets? What the Rules Actually Say

A few weeks ago I stood in a dairy in Newcastle and asked a farmer a simple question. Is anybody doing a delivery service for raw milk?

He told me you can’t sell it in a shop. You can sell it off the farm, or you can run a milk round, and that’s more or less it.

I’ve been thinking about that ever since, because most of us have walked down the milk aisle our whole lives without noticing it’s one very particular slice of what milk can be. So I did some digging. This is what I found, written the way I’d explain it to a mate.

One thing before we start. I’m not a scientist or a lawyer, and I’m not here to tell you what to drink. I want you to understand your milk. What you do with that is up to you.

First, what is raw milk?

Raw milk is milk straight from the cow that hasn’t been heat-treated. It’s cooled, bottled and sold. That’s it.

Nearly all the milk you’ve ever bought in a shop has been pasteurised, which means heated to kill bacteria. Raw milk skips that step.

In the UK it’s called “raw drinking milk” in the rules, and it’s a very different product, legally, from the milk in the supermarket.

Why can’t you buy it in a supermarket?

The short version is that the rules treat raw milk as a higher-risk product, so they limit how it reaches you.

In England, as far as I can tell, raw drinking milk can only be sold directly to the person who’s going to drink it. That means:

• At the farm gate. You turn up at the farm and buy it.
• From a vending machine on the farm. This is what the farm I visited does. You fill your own bottle.
• Through a milk round or home delivery. It still has to be kept refrigerated.

What it can’t do is go through a shop. There’s no middleman, no shelf and no supermarket warehouse. The idea behind that is that the person selling it is the person responsible for it, and they’re easy to trace.

Is that fair? People disagree, and I’ll come back to that. First, here’s what the producers have to do, because it’s more than you’d think.

What a raw milk farm has to do

According to the National Farmers’ Union’s summary of the rules, a farm selling raw drinking milk needs to:

• Register with the Food Standards Agency. If they supply it to a point of sale, they register as a distributor too.
• Keep a healthy herd. The cows have to be free of bovine TB, and the farm, milking parlour and dairy have to meet hygiene rules.
• Keep it cold. Milk has to be refrigerated, including on a round, and use-by dates have to be clearly shown.
• Test it. Regular testing is advised for the bacteria that cause trouble, including E. coli, Salmonella, Campylobacter and Listeria.
• Label it with a warning. In England the label has to say: “This milk has not been heat treated and may contain organisms harmful to health.” Cream has to say it’s made with raw milk.

So it’s far from a free-for-all. It’s a small, regulated corner of the dairy world.

It’s different depending on where you live

The rules change across the UK:

• England: legal, under the conditions above.
• Wales: legal. The Welsh labelling rules were the model England was moving towards.
• Northern Ireland: legal.
• Scotland: banned completely. You can’t sell raw drinking milk there at all.

The rules have been reviewed and tweaked more than once, so check the current Food Standards Agency guidance before you act on any of this.

Why the rules exist: the risk

I’m not going to pretend there’s no argument here, because there is. The official line is that raw milk can carry bacteria that cause illness, including E. coli, Salmonella, Campylobacter and Listeria. The Food Standards Agency’s advice is that pasteurised milk is the safer choice, and that raw milk isn’t recommended for people who are more vulnerable, such as young children, pregnant women, older people and anyone with a weakened immune system.

That’s the reason for the warning on the label.

Farmers and fans of raw milk see it differently. They’d say that milk from a well-run, regularly tested herd, kept clean and cold, is a world away from industrial milk, and that the risk comes from poor hygiene, not from the milk itself. Many say they’ve drunk it all their lives. The farmer I met has built part of his business around it.

I’m not going to pick a side for you. Both views come with real evidence and real feeling. If you’re curious, ask the farmer how they test, how they clean, and how often. A good one will be glad you asked.

So what’s the difference between all the milks?

This is the bit I thought was most interesting, because “milk” on the shelf covers a surprising range of products.

Raw milk
Straight from the cow, cooled and bottled. No heat treatment. It tastes fuller and a bit different, and the cream often rises to the top if it hasn’t been homogenised. It has a very short shelf life because nothing has been done to extend it, and it needs to be kept cold.

Pasteurised milk
This is the milk most of us grew up on. It’s heated to kill harmful bacteria. The common method heats it to about 72°C for 15 seconds. An older “batch” method heats it to about 63°C for 30 minutes. It keeps for around a week or so in the fridge, depending on the brand.

Homogenised milk
Not the same thing as pasteurised. Homogenising breaks the fat into tiny droplets so the cream doesn’t separate and rise to the top. Most supermarket milk is pasteurised and homogenised. Some producers sell milk that’s pasteurised but not homogenised, sometimes called “cream-top”.

Filtered milk (microfiltered)
This is milk that’s been passed through very fine filters to remove more bacteria before being pasteurised, which gives it a longer fridge life. You’ll see it sold as “fresh filtered” milk. It tastes close to ordinary milk but lasts longer.

UHT milk
UHT stands for ultra-high temperature. The milk is heated to around 135°C for a second or two, then packed into sterile cartons. It keeps for months without a fridge until opened. It’s convenient, and the taste is noticeably different to a lot of people.

Skimmed, semi-skimmed and whole
These are about fat, not processing. Whole milk has most of its natural fat, semi-skimmed has about half, and skimmed has almost none. The milk is separated and then put back together to the right level.

Organic milk
This is about how the cow was kept and fed, not how the milk is treated afterwards. You can get organic raw milk, organic pasteurised milk and organic UHT milk. The farm I visited is organic, and the farmer told me he doesn’t buy in feed.

Carton versus glass versus plastic
The container doesn’t change the milk, but it changes how long it keeps and how it’s stored. UHT goes in sealed cartons, a lot of supermarket milk goes in plastic bottles, and a lot of farm milk goes into glass bottles you can refill.

What about the nutrition?

You’ll hear big claims from both camps, so I’ll keep this short and honest.

Pasteurisation is generally said to preserve most of milk’s protein and calcium. People who prefer raw milk argue that heating reduces certain enzymes and some vitamins, and that the milk is better for you as a result. Those claims are disputed, and I’m not going to put numbers on them, because I haven’t seen figures I’d trust enough to repeat.

What I can say is that the biggest differences you’ll notice are taste, texture, shelf life and where it comes from. Those are real. Whether the nutritional claims hold up is something you can read up on yourself.

Why this matters beyond milk

When I asked about raw milk deliveries, the farmer explained why milk rounds mostly disappeared. It wasn’t because people stopped caring. It came down to shift patterns, parked cars, fuel costs and doorsteps you can’t trust any more.

I think this is the real story. Rules, costs and habits have built a food system where the big supermarkets are the easy option, and small farms have to work much harder to reach you.

If you’re curious about raw milk, or about milk generally, here’s what I’d suggest:

• Find your nearest dairy farm or farm shop. You’d be surprised how many sell milk direct, raw or pasteurised.
• Ask questions. What does the herd eat? How is the milk tested? How is it cooled and bottled?
• Try something different. Cream-top pasteurised milk, a glass bottle, a different supplier. Taste the difference for yourself.
• Talk about it. Small producers don’t have marketing budgets. A recommendation to a friend goes a long way.

If you decide to buy raw milk, buy it from a registered farm that follows the rules, keep it cold, and read the label. If you’re pregnant, have young children or have a weakened immune system, follow the Food Standards Agency’s advice and speak to your doctor.

Where can you buy raw milk?

Right, you’re sold. Or at least curious. So where do you get it?

Not in a supermarket, as we’ve covered. Here’s where it actually turns up:

1. Straight from the farm.
The classic. You turn up, you buy it. Some farms have a little shop or a fridge by the gate, and some will have a chat with you while you’re there (the good ones love it).

2. A farm vending machine.
This is what the farm I visited does. You bring your own bottle, fill it from the machine and pay. It’s open when the farm’s closed, which is the whole point.

3. A milk round or home delivery.
Some farms still deliver, and it has to stay refrigerated the whole way. Ask your local dairy farm if they do a round, because plenty don’t advertise it.

How to find a producer near you

• Use the official list. The Food Standards Agency publishes a list of every raw drinking milk premises registered in England, Wales and Northern Ireland. It’s free and updated monthly, so you can check that a farm is actually registered.
• Search “raw milk” plus your nearest town and look at farm websites and social pages. Most producers say clearly whether they sell by vending machine, delivery or farm shop.
• Ask at your local farm shop. They’ll often know who’s nearby.

What to check before you buy

• They’re registered. The FSA advises buying only from registered producers.
• The label has the official warning on it and a clear use-by date.
• It’s kept cold. If it’s sitting out, walk away.
• Ask how they test. FSA inspectors visit raw milk farms regularly, but it’s still fair to ask how the farm tests and cleans. A good producer will happily tell you.

And in Scotland? You can’t buy it. Raw drinking milk can’t be sold there at all.

Finally, the FSA says raw milk isn’t recommended for pregnant women, babies and young children, older people, or anyone with a weakened immune system. If that’s you or someone you’re buying for, stick to pasteurised.
