Picture two farms side by side. One sits in the English countryside, the other just outside a small American town. Both raise pigs.
In the UK farm, sows move freely in group housing, turning around, lying down, interacting with each other like the social animals they are. In the American one, a sow may spend most of her pregnant life in a metal gestation crate barely bigger than her own body, unable to turn around at all.
That’s not a hypothetical. It’s current law. Gestation crates have been banned in the United Kingdom since 1999. In parts of the United States, they’re still standard practice.
It turns out this pattern repeats across a surprising number of everyday farming practices. Countries from New Zealand to Switzerland to Germany have passed laws restricting or outright banning methods that remain perfectly legal in most of America, often because there’s no federal law addressing farm animal treatment at all. Below are twelve examples of that gap, country by country, practice by practice.
Key Takeaways
- The US has no comprehensive federal law regulating how farm animals are raised, unlike the EU, UK, and several other nations.
- Practices banned abroad decades ago, like battery cages and gestation crates, remain legal in most US states.
- Some US states, including California and Massachusetts, have passed their own bans that exceed federal standards.
- Regulatory gaps often come down to enforcement structure, not necessarily animal biology or need.
- Consumer-facing labels like ‘cage-free’ and ‘crate-free’ exist partly because federal law hasn’t caught up to consumer expectation.
Why the US Lags Behind on Farm Animal Welfare Law
The core issue isn’t that American farmers are uniquely indifferent to animal welfare. It’s structural.
The US Animal Welfare Act, the country’s main federal animal protection law, explicitly excludes farm animals raised for food. The two other major federal laws touching animal agriculture, the Humane Methods of Slaughter Act and the Twenty-Eight Hour Law, govern narrow slices of the process: how animals are killed and how long they can be transported without rest, respectively.
Neither says anything about how an animal lives day to day.
That leaves welfare standards for housing, space, and routine physical alterations almost entirely up to individual states and, in practice, to the industry itself. Some states have stepped in with their own laws.
Most haven’t. Meanwhile, the European Union has issued welfare directives that apply uniformly across 27 member countries, and nations like the UK, Switzerland, and New Zealand have passed their own even stricter national rules.
The result is a patchwork in America and a much more uniform floor of protection almost everywhere else in the developed world.
12 Practices Banned Abroad but Still Standard in the US
Each of these practices has been restricted or banned in at least one country, often several. Each remains legal under US federal law, though a handful of states have passed their own restrictions.
1. Gestation Crates for Pregnant Pigs
Gestation crates are narrow metal enclosures that confine a pregnant sow so tightly she cannot turn around for most of her pregnancy. The United Kingdom banned their use beyond the first four weeks of pregnancy in 1999, and the European Union restricted them across all member states starting in 2013.
In the US, crates remain legal in most states. Only a handful, including California, Massachusetts, Florida, and a few others, have passed bans, and even those often allow exemptions or long phase-in periods.
2. Battery Cages for Egg-Laying Hens
Battery cages are small wire enclosures that give each hen roughly the space of a sheet of paper, not enough room to spread her wings. The EU banned conventional battery cages in 2012, replacing them with ‘enriched’ cages that offer more space and perches.
Switzerland banned battery cages entirely back in 1992. In the US, they’re still the dominant housing system for egg-laying hens nationally, though California, Massachusetts, and a growing list of states have passed cage-free mandates that are gradually shifting the market.
3. Routine Beak Trimming Without Pain Relief
Beak trimming, cutting off part of a chick’s beak to prevent injurious pecking in crowded housing, is common in the US egg industry and typically done without anesthesia.
Norway and Sweden ban the practice outright, tackling the root cause of pecking, overcrowding, instead of the symptom.
The EU permits it only as a last resort and requires it be done as early as possible to reduce pain, with several member states pushing toward elimination. In America, no federal law restricts it.
4. Farrowing Crates for Nursing Sows
Similar to gestation crates but used after birth, farrowing crates confine a sow while she nurses piglets, again preventing her from turning around, ostensibly to reduce the risk of her crushing piglets. Norway and Sweden have both restricted or banned farrowing crates in favor of systems that allow more movement.
The practice remains legal and widespread in the US with no federal restriction.
5. Tail Docking Without Anesthesia
Tail docking, cutting off part of a pig’s or dairy cow’s tail, is often done to prevent tail-biting injuries in crowded pens or to keep cows cleaner in confined housing. The EU has banned routine tail docking in pigs since 1994, again framing overcrowding as the real problem to solve.
The UK bans tail docking of cattle entirely. In the US, tail docking of pigs remains legal and common, and dairy cow tail docking, while discouraged by veterinary groups, is still legal in most states.
6. Veal Crates for Calves
Veal crates confine young calves individually in spaces too small to turn around or lie down comfortably, a practice originally meant to keep veal meat pale and tender. The EU banned individual veal crates (beyond eight weeks of age) in 2007.
The US doesn’t have a federal ban, though the American Veal Association has voluntarily moved much of the industry toward group housing, and several major restaurant chains have pushed suppliers toward crate-free veal even without a legal mandate.
7. Forced Molting Through Starvation
Forced molting is a technique used to reset a hen’s egg-laying cycle by withholding food, sometimes for a week or more, to induce a stress molt that resets productivity. The EU has effectively banned starvation-based molting through its general welfare codes requiring continuous access to feed.
In the US, the practice is legal, though the egg industry’s own guidelines (from United Egg Producers) recommend against extended feed withdrawal, an industry standard, not a law.
8. Mulesing of Sheep
Mulesing involves cutting flaps of skin from around a sheep’s rear to prevent flystrike, typically done without pain relief. While mulesing is more associated with Australian wool production than US farming, it illustrates the same regulatory pattern: New Zealand banned the practice outright in 2018, favoring breeding and other flystrike-prevention methods instead.
The US doesn’t produce wool at the same scale, but no federal law would prevent the practice here, and enforcement falls to a patchwork of state animal cruelty statutes not written with livestock specifics in mind.
9. Extreme Confinement Without Minimum Space Requirements
Several countries set specific, enforceable minimum space allowances per animal, square footage or centimeters an animal must have regardless of housing system. Germany and the Netherlands both have detailed, legally binding space requirements for pigs and poultry.
The US has no federal minimum space standard for any commercially farmed land animal. Space requirements, where they exist at all, come from state law, retailer purchasing standards, or voluntary industry certification programs like Certified Humane, none of which carry the force of federal law.
10. Force-Feeding for Foie Gras
Force-feeding ducks or geese to enlarge their livers for foie gras involves inserting a tube down the bird’s throat multiple times a day. It’s banned in most of Europe, including Germany, the UK, Italy, and several other countries, along with Israel and India.
It’s legal under US federal law, though California passed a state ban that has faced repeated legal challenges and periods of non-enforcement, illustrating how fragile state-level bans can be compared to a genuine national law.
11. Castration Without Anesthesia
Castrating piglets without any pain relief is standard in much of the US pork industry, done to prevent an off-flavor in meat called ‘boar taint.’ Norway requires anesthesia for the procedure. Switzerland requires either anesthesia or an alternative method entirely.
The EU has committed member states to phasing out non-anesthetic castration. No such requirement exists in US federal law, and the procedure is typically performed by farm workers rather than veterinarians.
12. Cages for Rabbits Raised for Meat
Commercial rabbit farming often uses small wire cages that restrict movement and prevent natural behaviors like hopping or standing fully upright.
Austria has banned cage systems for farmed rabbits, and several other EU countries have introduced minimum enrichment and space requirements specific to rabbits.
Rabbit farming is a smaller industry in the US, but where it exists, it’s essentially unregulated at the federal level, with no specific caging standards at all.
How the Regulatory Gap Actually Plays Out
It’s worth being precise about what ‘banned’ and ‘legal’ mean here, because the picture is messier than a simple yes-or-no. In several countries, these aren’t outright prohibitions on the practice existing anywhere, but rather binding, enforceable standards with inspection regimes behind them.
In the US, by contrast, even where a state has passed a ban, enforcement mechanisms and funding vary enormously, and interstate commerce can complicate things further: a state can ban the sale of eggs from caged hens within its borders, as California did with Proposition 12, but that law only reaches producers who want to sell there, not producers everywhere.
The Humane Society and other groups have documented this patchwork extensively, pointing out that without a federal floor, welfare standards in America depend heavily on which state an animal happens to be raised in, and increasingly, on private retailer and restaurant purchasing commitments that fill the gap federal law leaves open.
Costco, McDonald’s, and other major buyers have made public commitments to cage-free eggs, for instance, effectively creating de facto standards that outpace the law itself.
Frequently Asked Questions
Is factory farming illegal anywhere in the world?
No single country has banned factory farming as a whole system. Instead, individual countries and the EU have banned or restricted specific practices within it, such as battery cages or gestation crates, while still permitting large-scale confinement agriculture in modified forms.
Why doesn’t the US have federal animal welfare laws for farm animals?
The main federal animal protection law, the Animal Welfare Act, explicitly excludes farm animals raised for food. Regulation of on-farm treatment has historically been left to individual states and industry self-regulation rather than federal agencies.
Which US states have the strongest farm animal welfare laws?
California and Massachusetts are generally considered to have the strongest state-level laws, including bans on gestation crates, battery cages, and veal crates through ballot measures like California’s Proposition 12.
Do ‘cage-free’ or ‘crate-free’ labels mean an animal was raised humanely?
Not necessarily. These labels describe the absence of one specific confinement system but don’t guarantee outdoor access, space per animal, or overall welfare. Third-party certifications like Certified Humane or Animal Welfare Approved involve more comprehensive standards.
Are imported foods held to the same standards as the exporting country’s laws?
Generally no. Once a food product enters the US, it’s typically subject to US food safety standards rather than the animal welfare laws of its country of origin, which is why products from countries with stricter welfare laws don’t guarantee the same conditions applied during production for every item on a shelf.
