Major supermarkets in the UK have recalled a number of food products issuing a "do not eat" warning on them.
The Food Standards Agency (FSA) flagged the issue which has affected products such as chocolate, cheese, popcorn and ready meals sold at Asda, Lidl and Sainsbury's.
The recall affects Lidl's Fin Carré Milk Chocolate with Hazelnuts, Asda's OMV! Mac ‘N’ No Cheese, and Sainsbury’s Mexican Style Chilli Cheddar.
