Mustard products containing traces of peanut can be found in food such as dips, sauces, salads and pre-packed sandwiches.
Last month FGS Ingredients said additional testing across its ingredients had “not detected any presence of peanut content or residue”, but advised customers to remove products from sale containing the mustard ingredients.
A spokesperson previously said: “We have never previously been involved in any incident of food contamination. Nevertheless, we continue to support the FSA investigation in every way necessary to help determine the source of this issue.”
The latest FSA notice, external said consumers had been advised to return the products for a full refund.
The FSA added: “These products are sold under several different brand names at several different retail stores.
“Point of sale notices will be displayed where the products were sold. These notices explain to customers why the products are being recalled and tell them what to do if they have bought the products.”
