> research I've seen seems to indicate that unless it's a food container it's pretty minimal

I use glass jars for storing food. One of the reasons is stuff like BPA leaching from the plastic to the food. Another is that it's much easier to have hundreds of identical jars to have a pretty and consistently filled kitchen cabinets. A third is that transparent plastic becomes less transparent after multiple washes with a sponge.

But what I hit "reply" for was to say that heating plays a role. So putting hot food inside a container is likely worse than putting something at room temperature in a container and then putting it in the fridge.

Wow, that's so little. I wonder if malicious BPA poisoning cases have been reported. It's probably undetectable unless you search for it specifically.

> The other problem is what do they replace BPA with?

I remember reading that BPA could be replaced with BPB. Obviously it may be OK, but to a layman it's like saying "we no longer add rat shit to our food, now it's bat shit".
