A number of products from a brand of US sweets are "unsafe to eat" and contain ingredients which could increase the risk of cancer and cause damage to DNA, the Food Standards Agency (FSA) has warned.
UK businesses and consumers are being urged to stop buying and selling the Jolly Ranchers products, owned by US company Hershey.
The FSA says they contain chemical compounds - mineral oil aromatic hydrocarbons (MOAH) and mineral oil saturated hydrocarbons (MOSH) - which are "not compliant with UK laws".
The products pose a safety risk if consumed regularly over time but there is "no immediate cause for concern, as [the] food safety risk is low", the agency adds.
In a food alert published on Wednesday evening, the FSA said: "MOAH can cause damage to DNA and has the potential to increase the risk of cancer, particularly if consumed in high quantities over a prolonged period of time.
"MOAH is a genotoxic carcinogen, therefore no exposure is without risk to human health."
MOAH and MOSH are used in confectionary to prevent stickiness and create a glossy appearance.
According to the agency, The Hershey Company has been working with the UK government body to remove the affected Jolly Rancher products from the UK market since 2024, but some businesses in Britain have continued to import the products.
The affected products are: Jolly Rancher Hard Candy, Jolly Rancher 'Misfits' Gummies, Jolly Rancher Hard Candy Fruity 2 in 1, and Jolly Ranchers Berry Gummies.
The food agency is advising people who have any of the listed products to not eat them and dispose of them at home. If consumers have any concerns, they are being asked to notify the Trading Standards department or environmental health department in the local authority they made the purchase from.
The agency said it was asking enforcement authorities to make "immediate contact" with businesses which had been supplied with or received any of the products, and take action to ensure they were withdrawn from the market.
