The supermarket chain has removed the affected product from its shelves and is calling on consumers not to use it after April 19.
The products in question were sold on April 12 and 13. It is however possible that some of them do not indicate the expiry date, which is April 19th. Customers who have purchased this salmon fillet are asked not to consume it beyond this date.
In the meantime, Delhaize has removed all affected products from the shelves and says it has tightened checks on the product and the supplier.
