I've been buying a couple generic brands of freezer bags the last few years, but I've gotten to wondering if I run the risk of buying something with BPAs or PFAS.
Should I stick with Food Saver brand? Any types of plastic bags to avoid?
Thanks.

May the fish be mighty and the seas be meek...

Most plastics release endocrine disruptors, BPA or not. I don't think there's a way around it. Maybe you could line the fish directly with parchment paper or some other barrier.

Probably less of a big deal with packaging/freezing fish as opposed to doing sous vide or vacuum packing acidic marinades which leaches a lot more crap into the food. Nothing like cooking your food in a plastic bag in a hot water bath for several hours... yum

Hum, I've been doing exactly that cooking breakfast in a freezer zip-lock in my JetBoil.  :smt009

Freezer Ziplock bags are polyethylene and vacuum seal bags are a laminate of polyethylene and polyamide. Neither should have either BPA or PFAS as additives or contaminants.

BPA is used in a number of polymers such as polycarbonate (Nalgene bottles) and the epoxy used to line steel cans. Side note, "BPA Free" in these contexts usually means they've switched BPA for something like BPS, which is probably just as bad, though there are safer alternatives.

PFAS are definitely used in food packaging and should not be, so your concern there isn't unwarranted. Watch out for greaseproof packaging, such as microwave popcorn and some fast food wrappers.
