A batch of children's yogurt has been recalled over fears it may contain a small piece of plastic.
Muller Kids Corner Butterflies Strawberry yogurt four-pack has been recalled as a precautionary measure because of the potential for a small puck-shaped disc to be present in one of the pots.
The pink disc measuring 3cm by 1cm is used to test systems on the production line, which are in place to protect product quality, the company said.
Manufactured in Market Drayton, Shropshire, the batch potentially affected is the four-pack of 135g servings, with a best before date of April 27 2016.
The Food Standards Agency, which issued the product information recall notice, told consumers: "If you have bought the product listed above, please do not eat it. Instead contact Muller Yogurt and Desserts at email@example.com."
A spokesman for Muller said: "This is an isolated incident and an extensive investigation by Muller Yogurt & Desserts quality team is under way."
The strawberry yogurt, with white chocolate and decorated cereal butterflies, is the only product thought to be affected - with the rest of the batch "entirely safe to eat", Muller said.
