This is one thing that makes me not want to use recycled stuff... There is a much wider variety of contamination in it.
Sure, we hopefully test for known-poisonous contamination, but there are all kinds of not-yet-known-to-be-poisonous contaminants, and recycled stuff has a much higher chance of having that than things made from new ingredients.
