Does anyone know of any toxins that might be produced/released by boiling water in coffee cans for drinking or cooking.

there are no toxins that can originate from the can itself. remember, coffee is a foodstuff, so the interior is food grade. You can of course die of carbon monoxide poisoning if you cook or heat in an enclosed space, ie automobile or even a canvas tent!!!!!

Inside is OK, outside, who knows.<br><br>I usually take the time to scrub the paint off with some fine sandpaper, before I use coffee cans for pots or to make stoves. I don't know what is in the paint, and I'd just as soon not find out the hard way.

Thanks for the info. I thought it was ok. I wondered because I do know that you can not drink the water you used to heat/boil the individual food packets of an MRE

In my experience, it's not the can, it's the plastic. The pouch meals used by the Canadian Armed Forces ("Freddy Chef" is the commercial version -- try the "chili con carnage") would stink up the water terribly, though the food in the pouch was not tainted. I'm sure if you drank that water you'd be ill.<br><br>Note, though, that cans seem to add an unusual flavour to the water. I prefer stainless steel cookware. If I'm using a can, I boil the jeepers out of it and discard the water before I cook with it.

I think he was talking about water that had been used in with MRE heaters. Those are a big chemical tab that you put in water and the reaction releases heat, hydrogen, oxygen and leaves all kinds of things in the water that you DON"T want in you. I'm not sure if they are nessacarily toxic, but I'd just as soon not be the test subject.
