Safety of glues in wooden chopping boards It seems to be becoming more difficult over time to get a wooden chopping board that isn't made of separate pieces of wood that are glued together.

I did find some sites discussing how to choose a food safe glue:

The latter site states "Boards that are not made with FDA-approved glues should not be used for food preparation as the toxins in the glue could leech into the food."

Is anyone aware of any studies done into whether the chopping boards generally for sale are actually safe? (For the US, does the FDA check when they are imported?)

Obviously the quantity of glue that would make it into food would be very low, and probably undetectable by taste or sight. Has anyone experienced any ill effects from using a chopping board made with glue that's not food safe?
My research led me to the fact that it is the glue that gets the FDA food-safe approval or not.  The Wood Whisperer's website addresses the different kinds of glues used for cutting boards:
