“A compound is considered safe (by the Food and Drug Administration) until proven otherwise.”
That's a ridiculously untrue statement. Try and add a chemical with unknown safety to a food product/cosmetic/medical device and see how long it takes the FDA to shut you down.
The FDA does have GRAS designation (generally recognized as safe) for many chemicals, but that is based on a large body of evidence that has demonstrated no (or manageable) safety concerns.
