The Food Standards Agency has put out a recall notice recalling thousands of sandwiches from shops over fears they may be unfit for human consumption.
The sandwiches, which are sold by the Great Northern Sandwich Company, Spar and Honest Crust have been recalled after chicken used in the products was found to have "blue discolouration".
The Food Standards Agency says the discolouration may indicate that the products are unfit for human consumption.
Customers are now being urged not to eat the sandwiches and to return them for a full refund.
All of the affected sandwiches have a use-by date up to and including 10 February.
