?So what is a "Trace Amount"? In mass? Relative to the amount an item might have as an ingredient? In idea?

Are you asking our *personal opinions*? Or, do you mean what *exactly* does a company mean when they list trace amounts?

My personal opinion is that sometimes companies find it easier to label it as "may contain" so that they don't have to face any legal issues. I guess it makes sense to be careful and label it if there are peanuts at the same manufacturing plant because of possible contamination. I have been very lucky with my daughter, as she has almost a sixth sense about whether a product contains peanuts or not. She has had "may contain" products in the past with no problems and other products she will smell it and feel that it does contain.

I am thinking that this is probably based on our individual situations, since what each of us is likely to consider "trace amounts" is likely to be what causes a noticable but non-severe reaction with a minimal ingestion.
Operating with that assumption, many of us here react to "peanut oil," yes? Hot-processed pn oil contains between 2-20 parts per million (or micrograms of pn per gram of oil) of peanut protein. (By the most conservative scientific evidence, this would likely require the ingestion of at least 2-8 mL to exceed a low reaction threshold.)
This is considered trace, in my opinion. I strongly suspect that this is also about like many "processed in a facility" foods. "May contains" can contain much more, of course, but sometimes contain less- since this is based on cleaning protocols and usually doesn't involve a constant deposition of pn dust from a neighboring production line.
Most chemists would consider any amount less than about 100 ppm ( parts per million) to be "trace"...
Hope this is what you meant.

I *personally* consider trace amounts to mean that a product/ingredient has been in contact with or run on the same line as a peanut containg product. (Assuming we are talking about trace amounts of peanuts.) Now, this is definitely NOT the criteria used by all companies.
Now, there is a separate question what does "May contain" mean. That one is trickier. I consider "May contain trace amounts" to mean it may have run on the same line or otherwise been in contact with, but not all companies feel that way.
One cereal company I contacted said that their box would say "May contain trace amounts of peanuts" if the farmer they got their corn from also had a peanut field because if the farmer walked from the peanut field into the corn field he could leave trace amounts. Yet a different company only lists if peanuts are actually an added ingredient. They do not release info about what plants or lines contain peanuts. Quite a difference.
My own personal safety zone is somewhere in the middle, but of the two companies I like the first company.

I agree with what has already been said.
Maggie0303, just curious, what "may contain" foods has your daughter had?

This was information I got from these boards a long time ago. Unfortunately I was never able to verify it's validity. Perhaps those of you better experienced with researching studies could find it.
I cannot vouch for the accuracy of this:
________________________________
Here is information concerning the use of "may contain..." on food labels. This study was conducted by LM Niemann, JJ Hylwka, and SL Hefle. It was presented at the 2000 AAAAI meeting:
[list][*][b][/*:m][*]18.2% (4 of 22) "may contain peanut" contained traces of peanut.[/*:m][*]12.5% (2 of 16) "manufactured on shared equipment" contained traces of peanut.[/*:m][*]20.8% (5 of 24) where peanut was listed at the end of ingredient list contained traces of peanut.
Peanut present was measured at concentrations from 1 to 2500 parts per million[/*:m][/list:u][/b]
