Now you are making assumptions. If you are going to say that then the same can be said for any product you buy in a supermarket - again it is not exclusive to fish. How can you count on the safety of the other food you buy? Why just pick on farmed salmon purchased from a store? Are you going to stop buying steaks or ribs if you find something wrong with them? If you had to return some beef, pork or chicken because something wasn't right with quality (of course that NEVER happens...lol) do you feel like your life is in peril if you decide to buy them again? You might change where you purchase meat or produce, but I doubt you will give it up all together.
Of course you deal with the lice on the fish when you clean them, but then you said this was about "safety and standards". Well, we know for a fact that lice won't harm you and things like this happen with products we buy in stores no matter how much QA/QC is done. It does not make it right, but we do not live in a perfect world where everything we buy is going to be A1 quality all the time. I once purchased pork ribs from Save-On Foods that smelled like sewage. Did I feel the need to go on Facebook to denounce the company that processed the ribs or the rancher that raised the pigs and call for a full recall of all their stock sold at Save-On? No, instead I took the ribs back to Save-On for a full refund and proceeded to purchase ribs again. I realize that once in awhile I am unfortunately going to purchase something that is not what I hoped it would be, but I trust that the store that I purchased the product from to provide good customer service in this regard. Sobey’s did what they were supposed to do under the circumstances and hopefully the supplier does a better job in presenting it's product. If not, I am sure another supplier will fill in the void. Merely assuming that some other problem likely exists because this was not caught is not really proof of another problem unless you can demonstrate it. Again, if you are going to do that then you need to bring other food products into the equation.
Ms Morton is merely piggy backing her own agenda to get rid of open net pen salmon farming on this particular issue; however, this is clearly a processing issue which again is not exclusive to fish. I guess you are feeling bad that you got duped by Ms Morton. Hang in there…lol.
