I can assure you, no dioxin is produced or released in a microwave. The minimimum temperature for dioxin to form is around 600 Celcius, and only in certain oxygen concentrations. Also, no "dripping" of carcinogens from plastic wrap occurs.

Better to use e.g. corningware, or corelle dishes, or the like. If you do cover food with plastic wrap, ensure it does not touch the food. The migration of plasticizers depends on contact. Migration is enhanced by fat. Some plasticizers and plastic monomers are endocrine-gland disrupters. Once that was recognized, government regulations have completed changed e.g. food packaging for microwavable foods. I won't declare those regulations to be perfect, but routine testing of consumer products is being carried out. You don't have to repackage or change the container type for microwavable food, but I guess it wouldn't hurt.

Excuse me for butting in here but I wanted to ask you how it is possible to keep plastic wrap from touching the food? Even if I don't have it touching the food when I insert it into the microwave, the wrap always ends up touching the food when I take it out.

Also, are microwave ovens and microwaved food all that safe to begin with? I use them but worry about it. I've read that it can actually change the chemical composition of food. For example, I read that baby formula when heated by microwave can change it to include a complelely new form of amino acid. Don't know if that's complete b.s. or not. What do you think? Better yet, what do you know?
