Black plastics are the ones to really avoid. The problem with the black plastic, so think sushi container, chicken container, any take out container, or those black forks that you have at parties. Those are not always, but often made of recycled plastic from recycled electronics. A study that was published found that those black plastics, like the black plastic spatula, those plastics contained a variety of chemicals that are known carcinogens. They have flame retardants, things that are just bad, bad chemicals. They seem to be even worse. Really avoiding the black plastic, especially heating those. So you think of your to go food, it's going hot on the black plastic that's causing those chemicals to leach into your food even more. I mentioned that heat causes the leaching of chemicals like BPA 55 times more. The black plastic.
