The debate over whether the UK should allow imports of chlorinated chicken from the USA has simmered for years, often flaring up during trade deal discussions.
With the UK now navigating its post-Brexit landscape, the question remains: is this a sensible move, or a step too far? Chlorinated chicken—poultry washed with chlorine-based solutions to kill bacteria like Salmonella and Campylobacter—offers clear benefits.

It’s a cheap, effective way to reduce pathogens, potentially lowering foodborne illness rates. In the US, where the practice is common, regulators like the USDA insist it’s safe, with chlorine levels so low they pose no health risk. The process could also keep poultry prices down, a boon for consumers facing rising costs. Plus, with global trade in focus, accepting US standards might smooth the path to lucrative deals.
But the objections are loud and persistent. Critics argue that chlorine washing is a bandage for poor hygiene earlier in production—think overcrowded farms or sloppy slaughterhouses.
The UK’s “farm to fork” approach prioritizes prevention over chemical fixes, a system many see as superior. There’s also the taste factor: some claim chlorinated chicken just doesn’t match the quality of British poultry.
Animal welfare is another sticking point—US farming practices often fall short of UK standards, raising ethical concerns.
And while the European Food Safety Authority says chlorine residues aren’t a direct threat, studies like one from Southampton University suggest the wash might mask surviving bacteria, leaving risks undetected.
Public sentiment leans heavily against it, with polls showing most Brits unwilling to trade standards for cheaper meat. UK farmers, too, fear being undercut by a flood of low-cost imports, threatening an industry already under pressure.
Trade negotiators might see it as a bargaining chip, but for many, it’s a line in the sand—symbolizing a broader clash between cost and quality.
So, should the UK adopt chlorinated chicken? The case for it rests on safety data and economic pragmatism, but the case against—rooted in health, welfare, and national pride—feels weightier. For now, the UK seems better off sticking to its guns. Chlorine might clean chicken, but it can’t wash away these deeper concerns.
EXTRA:
There is no definitive evidence that McDonald’s uses chlorinated chicken in the UK.
Chlorine-washed chicken is banned in the UK and the European Union due to concerns over hygiene and animal welfare standards, a regulation that has been in place since 1997 and continued post-Brexit. McDonald’s UK has emphasized its commitment to sourcing ingredients that meet local standards, stating on its website that it uses “100% chicken breast meat” in products like Chicken McNuggets and sources poultry from suppliers adhering to UK and EU welfare and safety regulations.
The claim that McDonald’s UK uses chlorinated chicken appears to stem from misinformation or confusion, possibly fueled by discussions around US-UK trade deals and the use of chlorine washes in American poultry production. However, McDonald’s UK has not publicly disclosed using such practices, and importing chlorinated chicken remains illegal in the UK. Without specific, credible evidence from McDonald’s or regulatory bodies confirming otherwise, it’s reasonable to conclude they do not use chlorinated chicken in the UK, aligning with legal and corporate standards.
