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.
