That is what we all hope, whenever we buy any kind of food, regardless if it is fish or algae.
But of course it is good to also verify whatever you can, because food standards may be too lax or not enforced well enough.
So I agree with the other poster that mentioned the risk of mercury content for fish products, which however exists for all marine products, including algae products, even if it is lower than for small fish and even lower than for large fish.
Nevertheless, I hope that any fish product or algae product that is sold would be sampled and analyzed from time to time to verify that it does not contain harmful substances.
