No. It will not burn off completely. As long as the materials exist they will continue to leach contaminants into your food. 

Unfortunately I am not the type of person to keep bookmarks and links to resources I've read. If the subject matter interests you. Then I highly encourage you to self verify. Just know it is a deep dark rabbit hole to climb down. You will never look at normal every day household items the same again if you dig too deep. 

Do the right thing, play it safe. You only have one body and you shouldn't gamble with your health. Especially with something so genuinely dangerous to it. 

I'm just one guy who knows thjngs, just had sex, about to go to bed, and I'm trying to save a life of someone I've never met. Just, because I am a hero at heart. Take care, stay amazing, and have a wonderful evening.  

 Thanks for the feedback
