Yoghurts sold in five supermarkets have been recalled over fears they contain pieces of rubber.

Yeo Valley, which manufactured the products, has told Asda, Co-operative, Sainsbury's, Tesco and Waitrose to remove a selection of yoghurts from their shelves.

The Food Standards Agency said they posed a ''possible risk to health''.

Customers who have bought any of the yoghurts are advised not to eat them. They can return to the supermarket where they were purchased for a refund.

The yoghurts include supermarket-own brands and some yoghurts from The Collective Dairy brand.
