After the recent thread on food safe glue, I emailed Gorilla Glue and asked. They replied with a detailed message. Essentially, they said that while they haven't gone through the FDA approval process, it is already in use in Denmark making things like cutting boards and such. They go on to say it is completely non-toxic after curing. The only caveat is that if subjected to temperatures over 212F for over 4 hrs (at a time) may lead to joint failure once cooled.
