Every UK slime recall and safety warning
Updated 2 October 2026 from official GOV.UK data
Quick answer
The UK government has issued 14 safety alerts about slime since 2021. 11 were for too much boron, the chemical that makes slime stretchy. The rest were for phthalates, chemicals used to soften plastic. 5 were sold through Amazon's marketplace. The legal boron limit for slime is 300 mg/kg, and failed samples have tested at up to 931.
Slime never really goes away, and Gui Gui slime is on Smyths' top toys list for Christmas 2026. Every alert here was a chemical problem. This page collects every official alert so you can check what's in the toy box.

Questions parents ask
Is slime safe for kids?
Slime from big toy brands is tested against UK toy safety rules. The problems turn up in cheap slime and slime kits: 11 of the 14 UK alerts were for too much boron, the chemical that makes slime stretchy. The legal limit for slime is 300 mg/kg, and failed samples have tested at more than twice that.
Why is boron in slime a problem?
Boron is what gives slime its stretch, so some is expected. Too much is the problem. The official alerts say excess boron may harm children's health by damaging the reproductive system, which is why the UK sets a limit for toys.
