Are Formic acid and Formaldehyde truly productions of the body?

Question

Are Formic acid and Formaldehyde truly productions of the body? If so, are they still harmful if someone consumes too much? (I'm writing a research report and I MUST know this or all my proof will be void.) Please, also state how you know the answer you give.

Answer 1

No, formaldehyde, even in as little of a concentration of .25 parts per million can harm you. Your body NEVER produces either. Now, fire ants on the other hand produce formic acid.
