Fatty fish accumulates heavy metales and other unhealthy components and pregnant women in Norway is told to limit the intake. But it has been controversial, the industry is not happy with these recommendations!
replyI can see this being sensible regarding, for example, swordfish, which is long lived apex predator. They get the bio accumulation of everything they eat. Farm salmon has a short life and a controlled diet. Where would they get heavy metals?
replyFrom what I understand the fjord are relatively enclosed ecosystems and tend to accumulate stuff from the human acitivies around it
replyCan you link to those recommendations? I can't find anything on the Norwegian public health sites specifically about farmed salmon.
replyFrom their food and over time, I assume? Since farmed salmon is fed and live a short life I would also assume that it has lower pollution levels than wild fish of similar size and composition.
replyYou are exactly wrong. Farmed salmon has very high levels of heavy metals and PCB because the water where they are farmed is slow moving accumulate pollution. Wild ocean fish swim in the open ocean where overall pollution is less. That’s why if you buy omega 3 tablets it needs to be from ocean fish otherwise you’re getting a high level of toxic chemicals.
replyI thought this was true for tuna and somewhat never registered it might be true for salmon too. I need to look this up and update, thank you.
replyGenerally speaking, heavy metals accumulate as you move up the food chain, so it will be true for any large fish.
replyGrowth hormones. It’s better now than some years ago, but still. Some claim the do not use them at all.
replyAnd they use a lot of antibiotics.
And there is some accumulation of dioxins and PCBs in the fat due to the feed, but this has also been approved somewhat.
>Some claim the do not use them at all.
replyIt is against the law in most if not all EU countries. It is also the dispute between US and EU agriculture trade.
FWIW, Norway is not a member of the EU - if that is what you are implying.
replyIf that is not your point, I apologize, but then I don’t see the connection (maybe you could elaborate?)
But Norway is part of the EEA and is therefore bound by many EU regulations.
reply> Astaxanthin for the color fair.
replyWhy is it fair? Wild salmon also consume astaxanthin.
It’s like complaining that the farmers are bad for trying to mimic the fish’s natural diet.
Farmed salmon meat is pink, whereas wild salmon meat is white/greyish. A dull color.
replyThey don’t put the coloring in the food to emulate natural food sources. They do it because it looks more appealing to most consumers.
I dont know what the fuck u r talking bout.
