Commercial fish are actually way better

In its 2022 survey of seafood, the FDA found much lower levels of PFAS in seafood from grocery stores. The median levels of total PFAS detected by the EPA were 280 times higher [in caught freshwater fish] than levels in commercially sold fish tested by the FDA.

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.
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

quote:

Reverse osmosis filters and two-stage filters reduced PFAS levels, including GenX, by 94% or more in water, though the small number of two-stage filters tested necessitates further testing to determine why they performed so well.

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.
Right, my point is it's not as simple as saltwater = better, freshwater = worse. Nor is it as simple as farmed = worse.

What’s the mechanism for farmed fish water having lower pfas than other freshwater?
Filtering in commercial aquaculture, both freshwater and saltwater, is presumably why commercial fish have lower PFAs
