Coca-cola have recalled all bottles of its bottled water, Dasani, because it contains illegal levels of a chemical called bromate.
This is the second embarassing episode for the drink, which was revealed to be tap water from Kent in February.
The chemical, which formed at the time the water was being purified, is not dangerous at low levels, and officials say no-one is at risk from the drink.
About 500,000 bottles are being taken off shelves in shops across the UK.
