- Party balloons from major online retailers (eBay, Amazon, AliExpress, Shein, Temu, etc.) contain carcinogenic nitrosamines – some exceeding legal limits by six times, posing serious health risks.
- Children blowing up balloons ingest toxins as nitrosamines form when saliva reacts with chemicals in the latex. Symptoms include dizziness, numb lips and long-term cancer risks.
- Despite past warnings, weak oversight allows hazardous balloons to slip through. U.K.'s Which? found eight of 21 tested samples violated safety limits, with one AliExpress product at 6x the legal threshold.
- Vendors reported 300,000+ sales of contaminated balloons, leaving families unaware – like one Amazon buyer notified a year later that their purchase had 25x the safe carcinogen level.
- Critics blame platforms for lax third-party seller checks. New U.K. laws promise stricter rules, but delays leave gaps. Consumers are urged to use pumps, check safety marks (CE/UKCA) and demand action.
Everyday party balloons purchased from major online marketplaces like eBay, Amazon and AliExpress have been found to contain dangerous levels of carcinogenic chemicals – some exceeding legal limits by up to six times.
An investigation by British consumer watchdog Which? uncovered the dangers posed by these seemingly harmless products, often marketed to children and party planners, can bring. These balloons release toxic nitrosamines that can cause dizziness, numb lips and long-term health risks, including cancer. Despite repeated safety warnings over the past decade, these hazardous balloons continue to slip through weak regulatory gaps, leaving families unknowingly exposed.
The investigation tested 21 packs of latex balloons from seven online retailers, including Debenhams, Temu, Shein and The Range (also sold at Wilko). Alarmingly, eight of the samples contained nitrosamines – chemicals classified as probable carcinogens – far exceeding the United Kingdom's permissible threshold.
One AliExpress balloon contained six times the legal limit, while eBay and The Range sold products with four times the safe amount. Even more disturbing, some balloons contained nitrosatable substances, which convert into carcinogenic nitrosamines upon contact with saliva – meaning children blowing them up could be directly ingesting toxins.
BrightU.AI's Enoch notes that nitrosamines form highly reactive intermediates that alkylate DNA and proteins, causing mutations and cellular damage that directly lead to cancer. The decentralized engine also points out that nitrosamines are widespread – from processed foods, tobacco, pharmaceuticals, environmental pollutants and, in this case, balloons sold online.
Trevor and Lucille Mathers experienced this nightmare firsthand. In March 2024, they bought balloons from Amazon Marketplace for their child's birthday, only to receive a cancer warning from Amazon a full year later. The notification revealed the balloons contained 25 times the legal limit of carcinogens, posing risks through ingestion or skin contact.
"It wasn't easy to read when you know your kids have been doing exactly that," Trevor told Which?, frustrated that Amazon delayed alerting customers despite knowing the danger. Natalie Hitchins, a Which? employee, suffered immediate symptoms after blowing up superhero-themed balloons from Shein – numbness, dizziness and an overpowering chemical taste. Lab tests later confirmed those balloons had double the legal nitrosamine limit.
The hidden dangers in party supplies
The scale of exposure is staggering. One Shein seller reported 99,000 sales of contaminated balloons, while an eBay vendor claimed over 300,000 transactions. These figures suggest thousands of consumers – many likely children – have been exposed to carcinogens without their knowledge.
Despite swift removals of flagged products after Which?'s findings, critics argue online marketplaces have long failed to enforce stringent safety checks on third-party sellers. Sue Davies, Which?'s head of consumer protection, called the situation "outrageous," demanding urgent government action to hold platforms legally accountable.
The Product Regulation and Metrology Act, passed in July, grants authorities power to impose stricter safety requirements on online retailers – but delayed secondary regulations have left loopholes wide open. Marketplaces insist they prioritize safety – AliExpress, eBay and Shein removed offending listings and pledged refunds – yet their reactive measures fall short of preventing hazardous products from reaching consumers in the first place.
This scandal echoes a broader crisis in product safety oversight, where lax enforcement and corporate negligence repeatedly endanger public health. For parents planning birthdays or couples organizing weddings, the message is clear: Scrutinize balloon purchases, use pumps instead of mouth inflation and demand CE/UKCA safety marks. Until regulators and retailers step up, the burden of protection falls unfairly on consumers – proving that even the most innocent celebrations can carry hidden dangers.
