Müller is recalling six Cadbury desserts amid fears the foods could be contaminated with listeria.
People who bought specific batches of the products have been warned not to eat them, with a refund offered if returned.
Müller said the recall was a precautionary measure.
The bacteria listeria can cause the rare infection listeriosis.
The NHS says it is usually not a problem for most people but can be a higher risk for those who are pregnant, newborn babies, over-65s and those with weakened immune systems.
Foods contaminated with listeria don’t always cause the disease.
The UK’s Food Standards Agency said the use-by-date of the items impacted include May 17 for the Crunchie and the Flake and May 18 for the others.
The items being recalled include:
- Cadbury Flake Chocolate Dessert
- Cadbury Dairy Milk Buttons Chocolate Dessert
- Cadbury Dairy Milk Chunks Chocolate Dessert
- Cadbury Daim Chocolate Dessert
- Cadbury Crunchie Chocolate Dessert
- Cadbury Heroes Chocolate Dessert
No other Müller products have been impacted.
