There is an article in the most recent American Woodturner saying the
conventional wisdom about food safe finishes has been wrong since an
article in Fine Woodworking in 1979. The article says there is no
proof that eating off of wood finishes that are totally cured (meaning
you cannot smell the finish) is bad for people. Another interesting
part of the article was it said salad-bowl finishes (recommended by
people as safe) were thinned varnish and had driers to cure the
finish. Once the stuff had dried they were safe but not before (or at
least nobody has any evidence they are not).

Has anyone ever heard of actual evidence (not anecdotal) of health
problems caused by eating from bowls with the finishes we aren't
suppose to use since they are not food safe? ? People may be
shortchanging their work by playing it safe. We are not talking
about lead paint here but may be acting like it. .

In an article Jeff Jewitt states:

"All finishes are non-toxic when fully cured, despite what you may have
read or heard. Once the solvents are evaporated, the cured film is safe
enough for contact with food. This does not mean that the finish itself
is safe to gobble up. It means that additives such as driers or
plasticizers are encapsulated enough so that they do not migrate to what
you’re eating. For edible finishes, wax and shellac are the only ones
I’m aware of (which is why apples and candy are coated with these)"
