The presence of a cancer-risk chemical in the popular Pepsi drink has sparked unease in the advance nations of the world. In the UK, Pepsi has been criticised by child food campaigners for refusing to change its ingredients to remove 4-methylimidazole (4-MI), a potential cancer-causing chemical.

The American drinks giant has altered its formulation in the US following a health alert over contamination with 4-methylimidazole (4-MI).

However, the company says it has ‘no plans’ to take the same precaution for its UK consumers and argues it is not necessary.

“The stance has been condemned by the Children’s Food Campaign, which says it is wrong for the company to operate such double standards when it comes to safety,” said a report in UK’s Daily Mail.

According to the paper: “Concerns about 4-MI emerged in the US earlier this year after health authorities in California put the substance on its official list of carcinogens.

“This meant that any standard 330ml can of cola containing more than 30micrograms (mcg) of 4-MI would have to carry a health warning.

“As a result, both Coca-Cola and Pepsi announced they would be changing the ingredients in all their colas in America to cut the level of 4-MI.”
