I bought a pack of their 2 extra large fish fillets in John Smiths beer batter. I've just took one out and when I've looked at the ingredients it says 54% fish EITHER Alaskan Pollock or Basa.To check which you have you have to look at the best before date and if there's a P after it you have Pollock or B it's Basa.Luckily mine is Pollock if it was Basa I would be taking it back. But I believe the problem is they are selling 2 different products and to all intents and purposes marketing them as the same thing. I reckon it's very underhand and shouldn't be allowed.
