The UK Government has launched a public consultation on proposals that could impact millions of products stocked in British supermarkets. Officials have outlined models for either a two- or three-year plan to introduce the change gradually.
The Department for Environment, Food and Rural Affairs (Defra) has unveiled plans to prohibit the use of carbon dioxide gas to stun pigs before slaughter, a move that could transform supply chains across major supermarkets. Presently, approximately 90 per cent of pigs in the UK are stunned using high concentrations of CO2 prior to slaughter, with some 10 to 11 million pigs slaughtered throughout the UK annually.
This technique is employed in the supply chains of major retailers including Tesco, Asda, Morrisons, Sainsbury’s, Aldi, Lidl, Co-op, Marks and Spencer, and Waitrose.
According to Defra, it seeks to ban the practice to tackle widespread concerns regarding animal suffering during the process.
An introduction to the consultation states: “The evidence that carbon dioxide gas stunning causes significant pain, suffering and distress to pigs at the time of killing is well known.
“There is now clear evidence that alternative permitted stunning methods, such as the use of inert gases, will significantly reduce these welfare issues for pigs. We believe that a ban on carbon dioxide stunning of pigs in slaughterhouses and knacker’s yards would result in a significant improvement to pig welfare at the time of killing, and that the transition away from carbon dioxide stunning should be managed in a way that allows the industry to make the necessary technological changes to convert current systems and maintain economic viability.”
Animal welfare campaigners from the RSPCA have praised the decision, following their prolonged efforts against CO2 stunning.

Thomas Schultz-Jagow, director of advocacy and prevention at the RSPCA, said: “Every year, millions of pigs suffer distress and pain when slaughtered using CO2, so this is a critical welfare issue
“No one wants to think about animals being slaughtered, but we cannot ignore how the food on our plates is produced, or we have no hope of progressing farmed animal welfare.”
He said consumers should think about the welfare of pigs and how pork products are made.
The expert said: “Pigs are sentient and intelligent animals and deserve a good quality life and a humane death. We welcome the Government’s commitment to end this slaughter method, and we will work with them to drive this critical change forward to improve the welfare of pigs as soon as possible.”
The consultation welcomes responses from all interested parties, including consumers, farm workers and those in the retail sector who wish to put forward their views.
Defra has set out possible transition periods of either two or three years, allowing abattoirs sufficient time to implement alternative approaches.
The public consultation will remain open until December 21. Submissions can be made online through the Defra websit
ANDY BURNHAM’S NEW SUPERMARKET BAN COULD AFFECT MILLIONS OF PRODUCTS – MAJOR CHANGE LOOMS FOR BRITISH SHOPPERS!
Millions of British shoppers could eventually see changes to the way pork products are produced and supplied to supermarkets under a major new government animal welfare proposal.
The plans, announced by the Department for Environment, Food and Rural Affairs (Defra) on 26 October 2026, could transform an important part of Britain’s pork industry. The proposal is to phase out the use of high concentrations of carbon dioxide (CO2) to stun pigs before slaughter.
Although the headline has sparked concerns about supermarket products, the proposal does not involve an immediate ban on pork, bacon, sausages or other familiar food items. Instead, it targets a specific slaughterhouse practice that is currently widely used throughout the UK.
The potential consequences, however, could extend across the supply chains of major supermarket retailers, including Tesco, Asda, Sainsbury’s, Morrisons, Aldi, Lidl, Co-op, Marks & Spencer and Waitrose.
For consumers, farmers and food manufacturers, the question is how quickly the industry can adapt without creating additional pressure on food prices.
A Major Change to Britain’s Pork Industry
The government wants to end the use of high-concentration CO2 gas to stun pigs before slaughter.
At present, this method is widely used in British slaughterhouses. Industry figures cited in recent reporting suggest that approximately 90% of pigs are stunned using this technique.
The government argues that the process can cause significant pain, fear and respiratory distress before the animals lose consciousness.
Defra believes that alternative methods could substantially improve animal welfare.
The consultation considers alternatives including inert gases such as argon and automated electrical stunning systems.
These technologies could allow slaughterhouses to move away from the existing practice while maintaining the ability to process animals efficiently.
However, changing equipment across an entire industry is not a simple task.
Slaughterhouses would need to assess their existing facilities, invest in new technology, train employees and ensure that new systems meet legal and operational requirements.
That is why the government is considering a gradual transition rather than an immediate prohibition.
Why Supermarkets Could Be Affected
The proposal could have consequences throughout Britain’s pork supply chain.
Supermarkets do not usually operate their own slaughterhouses. Instead, they purchase meat from suppliers and processors who must meet specific production, food safety and animal welfare standards.
If the government introduces a prohibition on CO2 stunning, suppliers will have to ensure that their production methods comply with the new requirements.
This could affect businesses producing:
- Fresh pork and pork joints.
- Bacon and gammon.
- Sausages and sausage rolls.
- Ham and cooked pork products.
- Ready meals containing pork.
- Sandwiches and other prepared foods.
It is important to understand that these products are not themselves being banned.
The proposed change concerns how pigs are stunned before slaughter, not whether supermarkets can continue selling pork.
Nevertheless, manufacturers and retailers may need to review supplier arrangements and production costs.
The scale of the change could be substantial because the method is currently used throughout much of the British pig-processing industry.
Why the Government Wants to End CO2 Stunning
Animal welfare is at the centre of the government’s proposal.
Pigs are intelligent and social animals, and scientific assessments have raised concerns about the distress caused by exposure to high concentrations of carbon dioxide.
The Animal Welfare Committee has examined the evidence and recommended moving away from this method.
According to the government’s assessment, alternative stunning technologies could reduce the suffering associated with the process.
The government argues that improving animal welfare should not stop when animals leave farms.
The conditions in which livestock are transported, handled and slaughtered are also important.
This is part of a wider animal welfare strategy intended to improve standards across British farming.
Supporters of the proposal believe that modern slaughterhouse technology should reflect the latest scientific understanding of animal welfare.
They also argue that consumers increasingly want greater transparency about how their food is produced.
Supermarkets Face an Important Decision
Major British retailers could face pressure to ensure that their pork suppliers are prepared for the proposed changes.
Tesco, Sainsbury’s, Asda and Morrisons all depend on extensive networks of food producers and processors.
A transition to alternative stunning methods would require coordination between slaughterhouses, equipment manufacturers, farmers and retailers.
The challenge is particularly important for smaller processors.
Large companies may have greater financial resources to invest in new equipment, while smaller businesses could face difficulties finding the money required for conversion.
The government has acknowledged these practical concerns and wants the consultation to gather evidence about the costs and feasibility of the proposed changes.
The aim is to improve animal welfare while maintaining the long-term economic viability of British pig production.
Could Pork Prices Increase?
One of the biggest questions for consumers is whether the proposed change could eventually make pork more expensive.
Introducing new equipment and changing production processes could create additional costs for slaughterhouses.
Businesses may also need to invest in staff training, maintenance and operational adjustments.
Those expenses could place pressure on suppliers.
Whether any additional costs eventually reach supermarket shelves would depend on several factors.
These include the price of new equipment, competition between processors, the availability of alternative technologies and the ability of businesses to absorb investment costs.
The government has indicated that it wants to minimise the impact on consumers.
However, it is too early to establish whether the proposed changes will affect the price of bacon, sausages or other pork products.
For families already concerned about grocery bills, this is an important issue that deserves careful consideration.
Two or Three Years to Make the Transition
The government recognises that the pork industry cannot change its production systems overnight.
Defra is therefore seeking views on different transition periods.
The two main options under consideration are:
A two-year transition: This would require businesses to make the necessary changes relatively quickly, bringing earlier animal welfare improvements but creating greater pressure on processors to invest.
A three-year transition: This would provide businesses with additional time to purchase equipment, modify facilities and organise their operations.
A longer transition could make implementation easier for some companies, although it would also mean that the existing practice would continue for longer.
The consultation also allows respondents to comment on whether a different approach would be more appropriate.
No final implementation date has yet been confirmed.
What Do Animal Welfare Campaigners Think?
Animal welfare organisations have welcomed the government’s willingness to consider ending the practice.
The RSPCA has supported efforts to move away from high-concentration CO2 stunning, arguing that pigs should not experience unnecessary pain and distress during slaughter.
Thomas Schultz-Jagow, the organisation’s director of advocacy and prevention, has described the issue as an important animal welfare concern.
Campaigners argue that improving conditions at the point of slaughter is a necessary part of responsible food production.
They also believe that consumers should be able to understand how the products they purchase are made.
However, the transition will require cooperation from the entire industry.
Without suitable alternatives, investment and effective implementation, the proposed reform could create difficulties for businesses.
Farmers and Food Producers Have Questions Too
While animal welfare organisations have welcomed the proposal, farmers and processors must consider its practical consequences.
Pig farming already involves substantial expenses, including animal feed, energy, labour, transport and veterinary care.
Slaughterhouses also operate in a competitive market where efficiency and reliability are essential.
Businesses will want reassurance that alternative stunning technologies are commercially available, legally permitted and suitable for their particular facilities.
They will also want to understand whether the government intends to provide financial assistance or other support during the transition.
These questions are particularly important for smaller operators.
A successful reform must take account of both animal welfare and the financial realities of British food production.
The Public Consultation: What Happens Next?
The consultation opened on 26 October 2026 and is scheduled to close on 21 December 2026.
Members of the public, farmers, supermarket representatives, slaughterhouse operators, animal welfare organisations and other interested parties can submit their views.
The government wants evidence on:
- The animal welfare benefits of ending CO2 stunning.
- The availability of alternative technologies.
- The financial costs for slaughterhouses.
- The practical challenges involved in changing equipment.
- The appropriate transition period.
- The potential impact on British pork production and consumers.
After the consultation closes, the government will need to consider the responses before determining the next steps.
Until then, the proposal should not be confused with an already implemented ban.
A Bigger Debate About the Future of British Food
This proposal raises a wider question about how Britain wants its food industry to operate.
Consumers want affordable food, farmers need financially sustainable businesses, supermarkets need reliable suppliers and animal welfare organisations want stronger protections for livestock.
These objectives are not necessarily incompatible, but achieving them requires careful planning.
The government must demonstrate that improvements in animal welfare can be delivered without placing unnecessary pressure on farmers, processors and households.
The pork industry is now facing an important period of consultation and preparation.
For shoppers, the immediate message is that familiar supermarket pork products are not being banned. The proposed reform concerns the technology used to stun pigs before slaughter.
Nevertheless, the changes could eventually affect thousands of businesses and the supply chains behind millions of food products.
WHAT DO YOU THINK?
Should Britain move away from CO2 stunning as quickly as possible to improve animal welfare?
Should supermarkets and food producers receive more time and financial support to adapt?
And could the changes eventually increase the price of everyday pork products?
The government now wants to hear from the public before deciding how this major industry transition should proceed.
