More than 45 different types of ready meals, including some intended for children, have been recalled from Sainsburys, Waitrose and Morrisons, after the Food Standards Agency issued a warning about a batch of potatoes.
These potatoes could potentially contain metal shreds after a piece of machinery broke on the production line.
The recalled ready meals are both adult and children's portions, including the 'by Sainsbury's' range of Kids' Sausage & Mash and a Kids' Fish Pie.
The Sainsbury's Taste the Difference range has also been affected, including their luxury shepherd's pie, cottage pie, and vegetable and berry lentil pie.
The contaminated potatoes were also used in Sainsbury's 'basics' as well as their 'Be Good To Yourself' range (a full list can be seen below).
Waitrose and Morrison's have only had to recall one ready meal each: Waitrose Creamy, Golden Smoked Haddock in Cheese Sauce, and Morrisons Carrot & Swede Mash.
The recall demonstrates how potatoes from one supplier are being used in basic and premium ranges of ready meals.
The recall was made after one Sainsbury's customer made a complaint earlier in the week about finding a shard of metal in their fish pie. The recall was issued on the same day.
HuffPost UK Parents contacted Sainsbury's for comment. A spokesperson said:
“We have been made aware that a very small piece of metal has been discovered in a single pack of our Be Good To Yourself Fish Pie.
“As a precautionary measure and in the interest of customer safety, we are recalling all potato-containing ready meal lines produced by the supplier who makes this product.”
A spokesperson from Waitrose told HuffPost UK Parents: "The safety of our products is of paramount important to us and so as a precaution we have withdrawn three date codes and we apologise to our customers for any inconvenience caused."
Morrisions have not yet responded to a request for a comment.
Recall notices have been put up throughout the supermarkets, explaining to customers which ready meals they need to recall.
Tweets have also shown that they have been sending out emails, as one lady wrote:
Many others are tweeting urgent recalls to spread the word.
