Popular supermarkets, Sainsbury's, Waitrose and Morrisons have been forced to recall a number of ready meals after small pieces of metal were found in them.
It's thought that all the products contained potatoes which had come from the same source.
According to the Daily Mail, the Food Standards Agency have highlighted 45 products that have been recalled.
Sainsbury's have withdrawn 43 meals including some of their ranges for children and some of their 'Be Good To Yourself' healthy products have also been included.
Waitrose has only had to recall one product, its Waitrose Creamy, Golden Smoked Haddock in Cheese Sauce.
Morrisons has withdrawn its 500g Carrot & Swede Mash product.
Some potato and coleslaw products were also recalled last week for the same reasons.
The recall was initiated this week when Sainsbury's received a complaint from a customer stating that they had found a piece of metal in their fish pie.
A Sainsbury's spokesman has said: "Customer safety is our top priority. We immediately removed the affected products from sale while we investigate with the supplier, issuing a public recall and offering customers a full refund."
The company has made sure to specify that these products are only affected if they are within the date codes listed in their recall notice.
"As a precautionary measure, and in the interest of customer safety, we are recalling all potato containing ready meal lines produced by this supplier. We are asking all customers who have bought this product to return it to their nearest Sainsbury's store, where they will receive a full refund.
"No other products or date codes are affected by this issue, and we apologise for the inconvenience this has caused."
The Chief Operating Officer of the Food Standards Agency, Jason Feeny, said: "The FSA is advising anyone who has bought these products not to eat them and return them to the shop where they were purchased. The pieces of metal which may be present are potentially harmful, so people should check whether they have bought any of the products."
A list of the products that have been recalled can be found on the Food Standards Agency website: food.gov.uk.
