#2It's surprising to me how much we don't understand about plastic still.
Years ago I was in a kitchen shop with an out of town friend and we saw some Sous Vide equipment. I told her that we had one and that you could either plastic bags or vacuum sealed bags to cook in the water. Her reaction was an immediate "absolutely not." That's when I realized that she worked in a lab that focused on plastics. Her big call out was that there's been studies on heat and how it relates to plastic breakdowns, but those are at high temperatures. There wasn't much related to lower level heats applied for longer periods of time. Based on what she knew from the other studies, she refused to go near anything like Sous Vide as she assumed it was way too risky.

#3> Experiments have shown that microwaving plastic baby food containers available on the shelves of U.S. stores can release huge numbers of plastic particles — in some cases, more than 2 billion nanoplastics and 4 million microplastics for every square centimeter of container.
> After two days, just 23% of kidney cells exposed to the highest concentrations had managed to survive — a much higher mortality rate than that observed in earlier studies of micro- and nanoplastic toxicity.
surprised I didn't see more studies like this when researching for avoiding plastics with our baby... its not like these are new materials/ technologies... right?

#4> then heated them at full power for three minutes in a 1,000-watt microwave
This seems like unrealistic use of a microwave. The liquids are likely boiling for well over a minute. Are people really boiling liquids in the containers they’re serving their infant children?
I’m not especially plastic-phobic but I also don’t think a reasonable person would think it is a good idea to boil liquids in their children’s bottles regardless of heating source.

We're all part of a giant experiment. It's a bad experiment too, in the sense that it doesn't really have a proper control group.

#8Oof how bad. Can they study dishwashing plastics next? Good thing I used glass. I think parents these days are rather more aware of plastic leaching than those of the previous generation.

I had the same thought so I bought thin silicone bags from Platinum Pure, on the assumption that silicone withstands much higher temperatures and leaches less. The only drawback is that the bags are not airtight.

First off, there are silicon sous vide bags.
Second… if you are at the level that a bag with meat in it for 2 hours at 140 degrees is too risky… you had better get working on that cabin in the woods.
