Campaigners are calling for a ban on a colouring linked to cancer which has been found in Coca-Cola sold in Britain.
A chemical in the caramel colouring that gives the drink its distinctive colour has been at the centre of a health alert in the United States.
Coca-Cola has recently switched to a new manufacturing process in America to bring down the level of the suspect chemical, 4-methylimidazole (4-MI).
But this precaution has not yet been taken in other countries such as Britain, where its products are the nation’s biggest selling soft drinks with sales of £1.1billion a year.
The amount of 4-MI found in regular Coca-Cola cans sold in Britain was 135 micrograms – some 34 times higher than the 4mcg level in the US, according to research by the US group Center For Science In The Public Interest in partnership with Britain’s Children’s Food Campaign.
