Lidl customers are being issued an urgent warning to return a popular fish product if they have bought one of the affected food items.
According to Food Standards Agency (FSA), people should not eat it and instead return it to the shop for a full refund.
In the recent warning they say that Lidl GB are "recalling Eridanous Greek Style Smoked Mackerel Fillet with Olives and Oregano with Soy Oil because Listeria monocytogenes has been found in the product."
