Yeah we hosed the fish up good. You can still probably eat fish from farms though.
Farmed fish are going to be at least as bad, and probably worse.

All the water is poisoned from pfas because it’s in the rainwater, globally. Also, the farmed fish are being fed from ag products grown in poison soil with poison water, or in the case of salmon, krill and poo poo to really get that bioaccumulation going. They’ve got a lot more problems than just the pfas.

The difference is that those are ocean fish. The ocean has lower concentrations than freshwater. That has nothing to do with being commercial or not. There’s no reason to think fish grown commercially in freshwater is magically better, when the fresh water in the farms is contaminated just like any other water. It’s not like they filter out the pfas, that’s not a thing.

Yeah just looked this up, for some reason I thought they were safer, :negative:
The best thing to do is just to not think about any of this.

When it says commercial fish are much better, that category includes saltwater and freshwater, farmed and wild-caught, canned and frozen -- anything that gets sold at the grocery store.

Here's the FDA's 2022 test results for commercial seafood. On p. 3, tilapia is an example of a farmed freshwater fish with lower PFA levels than home-caught freshwater fish. On the other hand, clams, despite being saltwater, are hosed.

If you have any evidence to back up your claim that farmed fish have higher levels of PFAs than home-caught freshwater fish, please post it.

e: caught your edit -- PFA filters are far from perfect but they do exist. Some are ineffective or even counterproductive, but some work
Tilapia are quite low on the food chain, so it’s an apples-to-oranges comparison with e.g. trout. Clams are from shallow coastal waters, subject to runoff. Even more importantly, they are filter feeders, so it makes no sense to compare them to fish. Shellfish have all kinds of garbage, especially heavy metals like cadmium. What’s the mechanism for farmed fish water having lower pfas than other freshwater?
