Where is it legal to sell breast milk?

In most of the English-speaking world, yes. And where the answer is no, it is almost never about safety. It comes down to one question every country answered decades ago, usually without thinking about mothers at all: is milk a food, or is it a piece of a person?

Four answers, one question

Every country's position falls into one of four families, and knowing which one you are in tells you almost everything. Two of them are open, one is closing, one is shut.

The useful thing about that list is what it isn't. Nobody banned the sale of milk because a batch went wrong. The countries that say no say it on principle, and the countries that say yes said yes before anyone thought to ask.

Where you can sell

United States

Legal, and barely regulated. There is no federal law against selling your own milk, and no state bans private sale between adults. The FDA publishes advice against buying milk from individuals or over the internet, which is worth reading and is not law.

Two states add a layer, and both aim at companies rather than mothers. New York sets standards for anyone distributing milk for a fee, and requires a for-profit milk bank or cooperative to meet HMBANA guidelines or stricter ones, and to accept milk only from a mother at least 180 days postpartum. California licenses milk banks as tissue banks, its statute being broad enough to count a bodily fluid as tissue and swallowing as transplantation. Neither reaches a woman selling her own stash to another family. Pennsylvania is the one to watch: a bill restricting the sale of human milk to entities licensed by its health department passed the state House 191 to 1 in June 2026 and went to the Senate. It is aimed at milk banks, and it is the clearest sign that the American state layer is thickening rather than thinning. Income is income, so keep records from the first sale.

United Kingdom

Legal, and treated as food, which is the good news hiding in a dull sentence. A mother selling regularly counts as a small home food business and registers with her local council, free, at least 28 days before she starts trading. Registration cannot be refused and there is no test to pass first. Our walkthrough of that form takes twenty minutes end to end.

Food law also means the FSA takes an interest when something goes wrong: it worked with Trading Standards on a recall of a commercial human milk product found to contain elevated lead, while donor milk from non-profit banks was untouched. That is the system behaving normally. The first £1,000 a year of casual trading income is covered by the trading allowance.

Canada

Legal, and close to identical to the UK in doctrine. The sale of human milk for consumption is not prohibited; it is regulated as a food under the Food and Drugs Act and must meet the same provisions as any other food. Health Canada recommends against buying unprocessed milk from private sources such as the internet, and points people to the milk banks as the only screened, pasteurised route. Advice, again, not prohibition.

Australia

Yes, with an asterisk. Human milk has no legal definition in Australia and its trade is unregulated, so the honest phrasing is that private sale is not illegal rather than that it is allowed. Queensland is the interesting exception: there, human breast milk is defined as food, so a business processing it must comply with the Food Act 2006, the Australia New Zealand Food Standards Code and the milk bank operational guidelines, and must hold a local council licence.

That gap is not going to sit there forever. Law and bioethics researchers have been arguing that human milk should have a legal definition and be regulated more like blood, and submissions making that case are in front of law reform bodies this year.

New Zealand

The same trans-Tasman food standards code applies, and we have not found a New Zealand rule that speaks to private sale either way. Trans-Tasman food regulators have started looking at human milk products, which suggests the gap is recognised. Treat New Zealand as Australia's position with less case history, and ask MPI if you are about to build anything on it.

Where you can't

France

A flat no, on grounds that have nothing to do with hygiene. French law treats breast milk as an element of the human body, and the principle of non-patrimonialité in article 16-5 of the Civil Code voids any commercial agreement covering the body, its elements or its products. Article 16-6 rules out payment to anyone for the collection of a product of their body. Giving milk away is not caught by that principle; selling it is. The route that stays open is donation to a lactarium, where the milk is collected, screened, pasteurised and sent to the babies who need it most.

Brazil

Banned, and the story behind it is the strongest argument anyone makes against a milk market. In 1985 a chemist, João Aprígio Guerra de Almeida, walked into a neonatal unit and found poor mothers selling their milk cheaply to feed better-off babies. He campaigned for a ban and got one, then built the alternative: Brazil now runs the largest publicly funded milk bank network in the world, collecting from around 150,000 women a year. If you only ever read one country's file, read this one.

India

Prohibited in practice. The FSSAI has refused to licence the processing and sale of human milk under the Food Safety and Standards Act 2006 and warned in 2024 that commercialisation is not permitted, with enforcement available against food businesses that try. A company selling human milk products under a dairy licence lost it in 2022, and a separate attempt to sell milk-derived products as an ayurvedic preparation was stopped the same year.

China

Technically closed, practically wide open, which is the least comfortable combination on this page. Health authorities said as early as 2000 that human milk should not be produced and sold as a commodity, but no substantive regulation or supervising department followed. The result is a grey market on resale apps and forums where sellers post photographs of soap, cream or storage bags and move buyers to private messaging to do the deal, at roughly 15 to 50 yuan per 100ml. Milk sold that way has no screening, no cold chain and no comeback.

Cambodia

Exports banned since 2017, after a US company bought milk from around 90 women in Phnom Penh and shipped it home to sell. UNICEF called the trade exploitative and said the milk should stay with Cambodian babies; the prime minister's letter said the country was not so poor that its mothers needed to sell their milk. Selling inside the country was not the target. Selling it out of the country was.

Japan

An unregulated market with an enforcement hook. The health ministry has said the rules and standards for trading breast milk simply do not exist, while treating the sale of adulterated milk as a food sanitation offence. That came after an online product tested at nearly a thousand times normal bacterial counts and contained a cow's milk protein that does not occur in human milk. Nothing to register, and no protection either.

The EU, and why it is going the other way

Anyone hoping Europe is simply slow to catch up has it backwards. Regulation (EU) 2024/1938 on substances of human origin names human breast milk in its scope, alongside blood, tissues and cells. Its founding principle is voluntary unpaid donation, and it settles the messy national picture on financial neutrality: a donor should be neither better nor worse off. Member states may allow fixed-rate allowances for expenses, with a ceiling set nationally, but paying for milk is not the model. It entered into force in August 2024 and applies from 7 August 2027.

That is why the Nordic examples read strangely from outside. Swedish milk banks pay per litre, tax free, and Norwegian and Danish banks reimburse pumping time, electricity and travel. Those are bank programmes operating inside a donation system, not a market, and it is the allowance model the new rules formalise. Germany illustrates the other half of the problem: milk is generally handled as a food, the milk banks are hospital-run and unpaid, and the rules on private sale are simply not written down.

The grey areas

Most of the confusion online comes from six places where two different questions get answered as one.

• Unregulated is not the same as permitted. Australia's position feels like a yes and is really an absence. Absences get filled, usually after an incident, and usually in the direction of more rules rather than fewer.
• The state and provincial layer. New York and California in the US, Pennsylvania if its bill passes, Queensland in Australia. Every one of those rules is aimed at an organisation handling other people's milk at volume, not at a mother with a chest freezer, but a headline about them reads like a ban.
• The platform is not the law. eBay and Craigslist both ban bodily fluids in their terms, which is a company policy and nothing to do with legality. The same goes for payment processors that decline the category. Being shown the door by a marketplace is the most common reason a woman concludes, wrongly, that what she is doing is illegal.
• Selling and shipping are separate permissions. Your right to sell at home says nothing about whether milk may cross a border. Several countries restrict bringing in human milk, so check the destination rules before agreeing to an international sale. The cold chain will usually defeat you before the paperwork does.
• Compensation versus payment. Sweden pays per litre and calls it compensation. The EU will allow a capped allowance and calls it financial neutrality. A US for-profit bank pays around $1.20 an ounce and calls it payment. The words matter to regulators, and the difference for you is whether the amount is set by a rule or by what your milk is worth.
• Tax. Wherever selling is legal, the money is income. It is a small, dull obligation and it is the one most first sellers forget.

One more, quieter than the rest: nothing in food law turns on who drinks the milk. Where milk is a food, the rules describe the milk and its handling. Who a seller chooses to sell to is hers to decide, which is why that setting belongs to her and not to us.

The conventions behind all of it

Underneath the national rules sit a few older agreements, and they explain why the prohibitions cluster the way they do.

• The Oviedo Convention, article 21: the human body and its parts shall not, as such, give rise to financial gain. The EU Charter of Fundamental Rights carries the same prohibition in article 3. That single sentence is the ancestor of the French position and the spine of the new EU regulation.
• The milk bank convention: donation is unpaid, milk is screened and pasteurised, and the sickest babies come first. It holds from Brazil to HMBANA in North America to the European banks, and it is why a bank will not pay you and should still be your first call if a neonatal unit needs milk.
• Milk kinship: in Islamic law, a child fed by a woman who is not their mother may acquire a kinship that bars later marriage. That makes anonymous milk transfer a serious matter rather than a squeamish one, and it is donation itself, not only sale, that the question touches. Iran runs a milk bank network under a ruling that bottle feeding does not create the tie; Singapore permits donation where medically indicated; Pakistan's first milk bank suspended operations after religious objection.
• The exploitation argument: Brazil and Cambodia are the two cases with real mothers behind them, and they deserve a straight answer rather than a slogan. Ours is that the seller sets her own price and keeps the money, that milk banks come first for fragile babies, and that the honest comparison is not a Brazilian bank network the UK and US do not have, but the ungoverned Facebook market a woman is using today.

This is a reading of the public record as at 15 September 2026, written to be useful rather than to be legal advice. Laws move. If you are building a business rather than clearing a freezer, check the current rule with your own regulator.
