What You'll Learn
Chlorinated chicken defined
Chlorinated chicken refers to chicken that has been treated with antimicrobial rinses or washes to remove harmful bacteria. These rinses are often referred to as Pathogen Reduction Treatments (PRTs) in the US. After the birds are slaughtered and eviscerated, they undergo a ""final washing procedure", where chemicals are applied as a spray or wash, or added to the water used to lower the carcass temperature.
Chlorinated chicken is common in the US poultry industry, with the National Chicken Council estimating that chlorine is used in less than 5% to 10% of processing plants. The practice is banned in the UK and the European Union (EU), which cites concerns over food safety and the belief that it compensates for poor hygiene and animal welfare practices earlier in the supply chain. The EU follows a "farm to fork" approach, emphasising high hygiene and animal welfare standards throughout production to prevent the spread of bacteria, eliminating the need for chlorine washes.
While the safety of chlorinated chicken is debated, some studies suggest that chlorine can make foodborne pathogens undetectable, giving the false impression that they have been eliminated when they may still be capable of causing disease. Research by Southampton University found that disease-causing bacteria like listeria and salmonella remain active after chlorine washing. This could pose a human health risk, as chlorine-washed chicken might still carry harmful bacteria.
The prospect of the UK accepting chlorinated chicken as part of a post-Brexit trade deal with the US has sparked concerns among campaigners, who argue against its entry into the UK food chain.

Safety concerns
Chlorinated chicken refers to chicken that has been treated with antimicrobial rinses in the form of chlorine to remove harmful bacteria such as salmonella, campylobacter, and E. coli. While the use of chlorine in chicken processing is common in the US, it has been banned in the UK and the EU over food safety concerns.
Food safety
The primary safety concern surrounding chlorinated chicken is the potential for it to disguise poor hygiene and animal welfare practices earlier in the production process. The EU, for instance, believes that relying on a chlorine rinse at the end of the meat production process could compensate for poor hygiene standards, such as dirty or crowded abattoirs. As a result, the EU has implemented a "farm-to-fork" approach, prioritizing high hygiene and animal welfare standards throughout the production process to reduce the risk of harmful bacteria developing. This approach promotes better public health outcomes and encourages proper hygiene practices.
Research has also found that disease-causing bacteria like listeria and salmonella can remain active after chlorine washing, making it difficult to detect these bacteria in labs. This gives the false impression that the bacteria have been eliminated when they may still be present and capable of causing illness. A study by the University of Southampton supports this, concluding that chlorine can make foodborne pathogens undetectable, leading to potential health risks.
Antibiotic resistance
The routine use of chlorine washes and antibiotics in chicken farming may contribute to antibiotic resistance. Chickens are often fed antibiotics as a preventative measure to stop infections, and then chlorine-washed after slaughter to kill bacteria. This practice can reduce the effectiveness of antibiotics for humans and promote the development of drug-resistant superbugs, which is a significant health concern.
Market competition and consumer awareness
There are also concerns about the potential impact of chlorinated chicken on market competition and consumer awareness. If the UK were to accept chlorinated chicken imports, it could drive down prices and put pressure on domestic farmers to lower their standards to remain competitive. This could result in a decline in hygiene and welfare standards across the industry. Additionally, consumers may not always be informed about the use of chlorine in chicken production, as food producers are not currently required to disclose this information on packaging or in restaurants.

Political implications
The issue of chlorinated chicken has been a contentious topic in political discussions, particularly between the United States and the European Union, including the United Kingdom. The debate revolves around the use of chlorine washes or rinses on poultry products to eliminate harmful bacteria such as Salmonella and Campylobacter.
Political Divide
The political implications of chlorinated chicken have created a divide between the US and the EU/UK, with differing views on food safety and hygiene standards. The UK and the EU have traditionally opposed the consumption and import of chlorinated chicken, with the practice being banned in these regions since 1997. They advocate for a "'farm-to-fork' approach, emphasizing high hygiene and animal welfare standards throughout the production process to prevent bacterial contamination. On the other hand, the US defends its use of chlorine washes, arguing that it is a safe and effective method to ensure food safety.
Trade Negotiations
The issue of chlorinated chicken has been a significant point of contention in trade negotiations between the US and the UK, especially in the context of Brexit. The UK's potential acceptance of chlorinated chicken as part of a post-Brexit trade deal with the US has sparked concerns among campaigners and consumers. They argue that allowing chlorinated chicken imports could set a precedent for lower hygiene and animal welfare standards, as well as create unfair competition for domestic farmers and producers. The UK government has faced internal disagreements on this matter, with some considering it a "'red line' in trade talks, while others view it as a negotiable detail.
Consumer Concerns
Consumer concerns about chlorinated chicken go beyond food safety. There are worries about the potential impact on domestic agriculture and the economy. Consumers fear that accepting chlorinated chicken could lead to a flood of cheap chicken imports from the US, driving down prices and affecting the livelihood of local farmers. Additionally, there are concerns about the lack of transparency in labelling, as food producers and restaurants are not currently required to disclose the use of chlorine in their poultry products.
Wider Concerns
The debate over chlorinated chicken also intersects with broader concerns around animal welfare, environmental standards, and the use of antibiotics and hormones in food production. The perception of '"industrialized farming"' in the US and its potential impact on animal welfare and environmental standards is a concern for some opponents of chlorinated chicken. Additionally, the routine use of antibiotics in poultry farming contributes to the issue of antimicrobial resistance, reducing the effectiveness of lifesaving drugs for humans. These interconnected issues have become crucial negotiating points in trade discussions between the US and the UK, highlighting the complex political implications of chlorinated chicken.

Animal welfare
Chlorinated chicken is chicken that has been treated with antimicrobial rinses, or pathogen reduction treatments (PRTs), to remove harmful bacteria. This process is banned in the UK and EU due to concerns over animal welfare and its potential to mask poor hygiene standards.
In the UK and EU, high hygiene and animal welfare standards are maintained throughout the production process to reduce the risk of harmful bacteria developing. This means chlorine washes are not necessary. In contrast, US farms are allowed to dip or wash chicken carcasses in water containing chlorine dioxide to kill harmful organisms such as E. coli, campylobacter, and Salmonella.
The concern is that the use of chlorine washes compensates for poor hygiene and low animal welfare standards on farms. For example, keeping chickens in large flocks in dirty conditions increases the likelihood of bacteria development and spread. Chickens in these conditions are often fed antibiotics as a preventative measure, which contributes to the problem of antibiotic resistance in humans.
The RSPCA, a UK animal welfare organisation, is deeply concerned that the practice of chlorine-washing chicken could lead to a decrease in farm welfare standards in the UK. They advocate for higher animal welfare standards, including providing chickens with more space than required by law and environmental enrichments such as perches and objects to peck at.
While the US insists that chlorinated chicken is safe for consumption, the EU and UK fear that accepting chlorinated chicken imports would be condoning lower animal welfare standards. This could also put pressure on UK farmers to lower their prices to compete with cheap, low-quality imports, further driving down hygiene and welfare standards.
