Animal rights and the food industry

We often think of the UK as having high standards when it comes to animal welfare, but is this really true?

One in five dairy cows have no access to pasture. Cage eggs are still used in many food products. Around 50% of sows are kept in farrowing crates for several weeks during the time they give birth.

These conditions all point to the lack of bodily autonomy for UK farm animals. And with the growth of industrial, factory animal farms, the situation is likely to be getting worse.

Animal rights and animal welfare issues in the food industry

For many, animal rights and the rearing of animals for food are incompatible. What stops animals having a right to life like humans? What makes our lives more important than theirs? Breeding, keeping and killing certain animals for food means that sentient beings are being exploited and traded as a commodity.

For others, how the animals spend their lives is most important. Peter Stevenson from Compassion in World Farming says that the system in the UK is deeply flawed and often “way short of what’s needed to ensure animals have lives worth living”.

Here, we run through some of the key welfare issues seen on some UK farms and what they mean in terms of animal rights.

1. Farm animals kept in overcrowded conditions

Many animals are kept in severely overcrowded conditions.

Over 60% of the world’s eggs, that is from nearly 4.5 billion hens, are still produced in industrialised systems, mainly battery cages. Whilst progress may have been made in the UK, there are still animal rights and welfare issues associated with eggs, even ‘good’ ones. The drawing below shows the relative space an indoor hen has:

There is a common misconception that free range eggs involve hens roaming outside, happy and free. Welfare standards can vary wildly between different free range producers, from small-scale egg farmers with hens in a field to industrial producers who adhere to the minimum standards.

Minimum free range standards still allow hens to be kept in vast, multi-tiered sheds with 16,000 or more other birds, and rarely see daylight. Under EU legislation, nine ‘free-range’ birds can occupy one square metre of floor space. That might be about twice as much room as a battery hen, but it’s still like 14 human adults living in a one-room flat.

While hens have to be given some kind of daytime access to the outside, with such confined spaces only very few birds will ever actually make it out the door. Even once there, the outside may not be the rural idyll you imagine. It can be a barren space with little or no vegetation.

The same story is seen for many other animals in the farming system. Animal Aid says, “the majority of farmed pigs are often forced to live standing and lying in their own waste.” Sows are often also kept in ‘farrowing crates’ for about a month around the time they give birth – metal and concrete cages just a few inches larger than the sow. 23% of farms also keep some or all dairy cows inside year-round, up from 16% in 2014. At least a fifth of all dairy cows in the UK are kept inside year-round. 

Factory farmed fish can also be kept in densely packed nets, where some end up riddled with lice and treated with strong chemicals.

These animals can be in dirty conditions, without adequate straw, and have nothing to interact or play with. Hens kept inside are given ‘enrichments’ (like pecking blocks and plastic toys) to help them express their natural behaviours – which speaks volumes about the unnatural conditions they are kept in.

2. Farm animals mutilated

Many animals are mutilated in order to ‘solve’ problems created by the industry.

Piglets can be taken from their mother at a young age and put into shared pens. Desperately trying to find their mother’s milk, they can try and suckle the other piglets or bite their tails. Some farms will amputate part of the piglets’ tails and clip their pointed side-teeth to avoid the problem. The amputation can be painful and result in infections. It’s banned in the UK, but campaigners say the majority of pigs still undergo this practice.
 

Likewise, hens, denied outside space for foraging, sometimes peck one another’s feathers. To avoid this, chicks have their beaks trimmed without anaesthetic. In 2011, the UK banned one of the worst forms of beak trimming, with a blade, although it is still legal in the US.

Similarly, virtually all dairy cows are born with horns, which are removed through a painful procedure so that they are less likely to cause injury and require less space in pens and feeders.

Lambs also face mutilations. Lambs' tails are docked with a knife, hot iron or tight ring. Male lambs are castrated using a tight ring, clamp or surgery, usually without anaesthetic.

3. Farm animals are continually impregnated and separated from their offspring

For both milk and meat production, female animals are impregnated usually at a much much faster rate than is natural for their bodies.

Animals of any species can only supply continuous milk if they are continually pregnant. On a dairy farm, a cow is restrained, and a farmer puts their arm into the cow and injects a gun full of semen into her cervix. A few months after giving birth she will be impregnated again, then be milked throughout most of her pregnancy. A few months after the next birth she will be impregnated again, and so on.

Shortly after birth, dairy calves are separated from their mothers so that the milk the calf would otherwise consume can be sold. Male calves usually end up as meat. Female calves usually become dairy cows like their mother. The process causes huge distress to both calf and mother.

Pigs face a similar cycle. Pigs would naturally feed their piglets for two or three months before weaning. Yet, piglets are usually taken away from their mother at three to four weeks so she can be impregnated again. This separation causes stress to both of them, but it also makes the mother come into season quicker than she otherwise naturally would, so she can have another litter again.

For animal rights activists, this use of animal’s reproductive systems epitomises the way in which we exploit animals’ bodies.

4. Farm animals forced to overproduce

Dairy cows are bred to produce six to ten times as much milk as a cow typically would for their calf. They are milked by machines multiple times per day and regularly suffer from mastitis (inflammation of breast tissue causing swelling, hotness and pain).

Likewise, farmed hens have been bred to lay 250-300 eggs a year – compared to just 10-15 eggs for their wild ancestors. This puts enormous strain on their bodies.

For many vegans, the very concept of an ethical egg is impossible. Animal rights group Peta argues that females’ rights over their own reproductive systems should be respected, no matter the species, asking: “can you call yourself a feminist if you eat eggs?”

5. Farm animals transported in scary conditions

Animals can be transported a long way, in scary conditions, particularly before slaughter.

Historically, they have been transported from the UK across continental Europe and even to countries like Israel. According to Compassion in World Farming,

“In the mid-1990s, over 2.5 million animals were transported live from the UK to be fattened and slaughtered in Europe. [...] this number has dropped significantly. However, thousands of calves and sheep are still exported by sea and road from the UK as far as Spain and Italy.”

Conditions can be overcrowded and scary. Pigs can die during transit due to the stress caused by overcrowding, long journeys, rough handling and extreme temperatures.

In August 2021, the UK announced that it was cracking down on live exports, meaning that cattle, sheep, goats and pigs could no longer be shipped from England, Scotland or Wales for fattening or slaughter abroad.

6. Farm animals are killed prematurely

Millions of animals are killed for meat every year in the UK long before their natural lifecycle would end. They may be slaughtered because the exploitation of their bodies has worn them out prematurely or because they are not ‘useful’ to the farming system.

If not selected for breeding, pigs will be killed for meat after four to seven months, cows are generally killed between 2-6 years, when they could naturally reach 20 years. Ewes are culled if they become less fertile or have problems giving birth – usually around three to six years old, a quarter to half of their natural life expectancy. Lambs, by the definition of lamb meat, are killed as babies, between ten weeks and six months old. They never become adult sheep.

A hen’s natural lifespan is 5-10 years, but farmed hens are ‘spent’ and killed after 72 weeks – that’s around 1.5 years – when their egg production begins to wane. At a hen’s lowest lifespan, that’s equivalent to a human being ‘spent’ at 24 years of age.

Male chicks are of no use for egg or meat production and are killed almost immediately after hatching. They are either thrown into an industrial grinder (‘macerator’) while still alive, or gassed to death, the preferred method in the UK. France, Germany and Italy have recently banned this practice.

Animal rights activists ask why we should have the right to define the lifespan of any other sentient animal.

7. Farm animals slaughtered in cruel conditions

When animals are slaughtered, this is sometimes done in cruel conditions.

RSPCA Assured says:

“Around one in ten farmed animals in the UK are not stunned before they are slaughtered though there are big differences between species, with around 25 per cent of sheep, 10 per cent of meat chickens but only two per cent or less of cattle, hens and turkeys being killed without pre-stunning. Potentially as many as 20 - 30 per cent of poultry are shackled upside down by their legs whilst conscious before being killed. This can cause animals a great deal of pain, stress and suffering.”

Compassion in World Farming also says that the majority of fish people consume “has been killed inhumanely”. On many fish farms, the routine approach is to pull fish out of the water, which they need to breathe, and let them suffocate in the air.

What are food companies doing about animal welfare and rights?

Lots of companies have animal welfare policies, with criteria like ‘freedom from hunger and thirst’. However, for many multinationals, the bar is very low. It can therefore be difficult to separate those talking the talk from those actually making changes.

Our ratings track companies’ records on animal welfare and animal rights. The highest scoring companies are those that use no animal products at all, followed by those only using very small amounts of animal products. 

For those companies that use significant amounts of animal-derived ingredients or materials, we give more marks to companies with more stringent welfare policies – for example, if they only use organic materials or ingredients then this shows it has one of the highest animal welfare standards in place. 

The major supermarkets score 0/100 across the board in our animal products category. Amazon, Asda, Iceland, and Lidl have the least stringent welfare policies of all. 

Luckily, more and more companies are moving away from animal products altogether – crucial from an animal rights perspective. In our chocolate guide we rated ten companies selling only vegan chocolate. 

In all our guides, we highlight the vegan alternatives so that you can avoid animal products altogether, for example dairy-free milk and dairy-free butter/margarine spreads.

What can consumers do?

1. Avoid animal products

For some, it will be important to avoid meat and/or dairy altogether. Check out our guides to vegan cheese, vegan & plant milks, and meat-free sausages and burgers, and look out for vegan options in many of our guides including chocolate and butter & spreads.

We highlight totally vegan companies, as well as vegan products or brands – so you can make sure none of your money is going to companies using animals.

2. Look for better animal welfare schemes

Others may want to continue eating meat and dairy but look for better practices. We have some tips to do this:

• Buy direct from a farm you trust – Find a farm you think looks good and spend time reading their website and, if you can, speaking to them. Look out for red flags like ‘zero-grazing’ as this generally means the animals are kept indoors all year round. Ask about enrichment, transportation and access to pasture. Local farms often sell directly at markets or through delivery.
• Speak to the retailer – If you buy from a butcher or local store, speak to them about what conditions they expect. They may be able to point you to the products associated with better welfare, and if they can’t you might get them thinking.
• Look out for labels – Stronger certification can be a good way to ensure better conditions. Below we run through the different options available and what they mean – as well as which ones actually make a difference in terms of animal rights.
• Use our guides – As well as highlighting vegan products and companies, we rate brands that do sell animal products on their standards. Use our guides to find the best of the bunch. In particular, our guides to dairy milk, eggs and butter & spreads point to the best of the bunch.
• Buy less, buy better – Meat and dairy with better animal welfare standards can be more expensive. Why not prioritise buying better but less of it? Our demand for so much meat and dairy is helping fuel the drive for ever increasing and cheaper production. This is also a good step to take when it comes to climate change and the environment.

3. Campaign for animal rights

If you want to go beyond changing buying habits, there are lots of animal rights campaigns out there in need of supporters. This could be signing a Viva! petition or getting involved in actions with Animal Rebellion and Compassion in World Farming.

Animal welfare labels on food and what they mean

There are lots of different animal welfare labels – some with truly higher standards than the norm and others which mean little to nothing. Each label should have different requirements for different animals, for example for hens vs sheep. Here, we run through some general guarantees that different labels for meat and dairy offer and separate the wheat from the chaff.

Labels for meat, dairy and eggs

Soil Association Organic

Soil Association’s Organic label is one of your best bets when it comes to eggs, meat and dairy. It is the strongest of the organic standards. Standards include:

• Access to pasture and space for all animals
• No routine use of antibiotics for all animals
• No beak trimming for chickens
• Five-times smaller chicken flocks than for free-range
• No tail docking or teeth trimming for pigs
• Fish must be killed humanely

Organic

Other organic standards can vary but standard requirements include:

• Animals should be grazed outside for most of the year (weather permitting)
• Minimum weaning age for calves is 12 weeks
• The routine use of antibiotics is prohibited
• Artificial pesticides cannot be used on the land
• No use of GM feed
• For eggs, Soil Association is certainly the best of the organic bunch

Pasture For Life

Pasture For Life (PFLA) is another of the strongest options, established by the farmer-led Pasture-Fed Livestock Association. The organisation champions the benefits of dairy (beef and lamb) production just from grass and pasture, with no grains being fed to the animals.

The Pasture for Life standard currently only applies to cow’s milk, beef and lamb, and its notable requirements include:

• No zero grazing
• Prohibiting the use of soya and GM animal feed
• Minimum weaning age for calves is 12 weeks
• Calves must not be killed (by the Pasture for Life farm) for any reason other than non-recoverable illness or injury
• Antibiotic use is kept to a minimum and reviewed on a case-by-case basis

Pasture Promise

Pasture Promise is another option focused on outside grazing for dairy products, but CIWF reckons that it offers a lower standard than Pasture for Life. Legally, free-range milk is yet to be defined and so The Free Range Dairy Network has developed their own working definition: the network requires its farmers to graze their cows outside for 180 days and nights a year (except in exceptional circumstances) before they can use the Free Range Pasture Promise logo on their products. They also prohibit free range dairy farmers from shooting calves unless it is ‘to alleviate pain or suffering’. No information could be found regarding this standard’s approach to antibiotic use.

Free Range

Unfortunately, Free Range is not quite the promise of open space and prancing lambs we often imagine. Welfare standards can vary wildly between different free range producers, from small-scale egg farmers with hens in a field to industrial producers who adhere to the minimum standards. 

For eggs, the minimum standards mean that many free range hens are kept in vast, multi-tiered sheds typically with 16,000 or more other birds, few of which ever see daylight. They must be given some kind of daytime outside access, but in such confined spaces only few birds are ever able to actually make it outside.

Animal welfare organisations CIWF consistently places free range amongst the lower assurances for animal welfare across all sectors.

RSPCA Assured

RSPCA Assured is slightly higher than the legal minimum. For example, for dairy cows a local anaesthetic is required when disbudding horns; embryo transfer and ovum pick-up are prohibited except in exceptional circumstances and outdoor grazing is encouraged. Antibiotics use is monitored and should be used only when ‘necessary’, with preventative measures being encouraged. Fish must be killed humanely. The use of GM animal feed is not prohibited.

However, there are many critics of the RSPCA Assured scheme. 60 animal welfare organisations plus politicians and celebrities have called for an immediate end to the scheme accusing it of “welfare-washing animal cruelty and misleading the public” in an open letter to the RSPCA. Chris Packham and Caroline Lucas have resigned as Presidents of the RSPCA, and Brian May resigned as vice president.

In 2024 the RSPCA announced that it would review the scheme and would make unannounced visits to 200 of the 4,000 farms covered. In October, their review was published and concluded that the scheme is “operating effectively to assure animal welfare on member farms”.

Red Tractor

You can basically ignore Red Tractor when it comes to animal welfare standards. It just means that the animal lived in the UK and was treated in line with minimum legal requirements.

CIWF says: “Some of the standards benefit animal welfare by going beyond minimum legislation, such as prohibiting castration of meat pigs, a slightly reduced stocking density for meat chickens and the requirement for on-farm health and welfare monitoring. However in some circumstances the standards inadequately reflect the legislation, such as provision for manipulable material for pigs, and do not address welfare issues not reflected in legislation, such as confinement of sows during farrowing and permanent housing and tethering of dairy cows.”

There have been multiple scandals involving the Red Tractor label in recent years. For example, in March 2025, campaign group the Animal Justice Project released footage showing cows being kicked, punched, and struck with bars and electric goads, and standing in ankle-deep water at a Red Tractor certified farm. 

A spokesman for Red Tractor told Farming Weekly that within eight hours of receiving the footage, an independent assessor was on the farm to investigate this “unacceptable behaviour by farm workers”. 

“This inspection confirmed all individuals identified mistreating animals no longer work on the farm,” it stated, adding that all current employees would be required to undergo additional training and further investigations were ongoing. 

For more information about what these various standards mean in each sector, check out our article on dairy standards and our shopping guide to eggs.

Individual labels

In 2022, Arla – the biggest dairy company in the UK – announced the launch of its C.A.R.E. standards, standing for Cooperative, Animal Welfare, Renewable Energy and Ecosystem.  However, as of 2024, the company still does not appear to have published the criteria for its standards online, making its claims that they are an “industry-leading requirement” look pretty empty.

Labels for fish

RSPCA Assured (farmed salmon and trout)

RSPCA Assured is probably the strongest label for animal welfare in terms of farmed fish. Unfortunately, it only covers farmed trout and salmon. Its criteria include:

• Fish must be stunned before slaughter and killed humanely
• For salmon, only 17 kg can be kept per m3 of water (which is stronger than its criteria for trout)
• Genetic engineering is prohibited
• Fish must not be kept out of the water for more than 15 seconds
• Antibiotics can only be used to treat (not prevent) disease
• A maximum time of 72 hours is given for ‘fasting duration’ (in which fish will not be fed)
• Water quality must be monitored
• Cleaner-fish (which help to clean dead skin etc. from the fish that are being farmed) have welfare conditions
   

Soil Association Organic (farmed)

There are a number of organic labels covering farmed fish, including Soil Association Organic. It ensures that the fish were stunned before slaughter and killed humanely. It limits the ‘maximum stocking density’, i.e. the weight of live fish allowed per m3. For example, for salmon only 20kg are allowed in each cubic meter. It also bans the use of antibiotics to prevent (rather than treat) disease.

However, it falls down in a few areas. For example, according to Compassion in World Farming (CIWF), it allows routine mutilations, only ensures enrichment for freshwater fish and does not have a maximum amount of time fish can be kept out of the water.

Soil Association Organic is slightly stronger than other organic labels e.g. it also ensures the welfare of ‘cleaner fish’.

Friends of the Sea (farmed and wild caught)

Friends of the Sea is a sustainability and animal welfare label for both farmed and wild caught fish. Its criteria include:

• Fish must be stunned before killing
• Only humane slaughter practices allowed
• Fish can only be kept out of water for a maximum of 15 seconds without anaesthesia
• Structural enrichment should be provided

However, like organic, CIWF says it permits routine mutilations. It is also weaker than Organic on crowding for farmed fish, allowing up to 60kg of trout per m3, compared to up to 25 for Organic, according to CIWF.

While it is probably the strongest option for wild caught fish, it is less good than RSPCA and Soil Association Organic when it comes to farmed fish.

Marine Stewardship Council (wild caught)

The blue MSC label can only be applied to wild caught fish. While this means that their lives were lived in more natural conditions, it doesn’t necessarily ensure they were caught or killed humanely. The MSC standard in fact does not include any specific animal welfare conditions. 

The MSC label focuses instead on sustainability. However, even in this area, its effectiveness has been called into question. 

In March 2022, the Netflix documentary Seaspiracy accused the MSC of certifying fisheries associated with high levels of bycatch – whereby dolphins, turtles and other animals are inadvertently captured along with the fish. 

MSC said the claims were “misleading”. “Some of the known problems that the film highlights – bycatch, overfishing and destruction of marine ecosystems – are precisely the issues the MSC certification process is designed to address,” a spokesperson told the Guardian. 

Weaker fish welfare labels include Global GAP, Best Aquaculture Practices (BAP), Certified Quality Aquaculture (CQA), and Aquaculture Stewardship Council. For more details check out the table from Compassion in World Farming.
