# How does the formaldehyde leak into the food from bamboo cutting board? [closed]

http://food.thefuntimesguide.com/2010/07/bamboo_cutting_board.php

Some bamboo cutting boards are glued together with adhesives that have formaldehyde in them — which could eventually leak into and contaminate food.

I wanted to understand the logic behind the above claim in italics.

The glue is between the sheets of bamboo cutting board. So, if I use only one side of cutting board all the time, will the gravitational force not stop the glue from going upwards and mix in the food?

Moreover, I have a thought that they use negligible amount of HCHO like 0.1 ppm or so which is not so harmful Are there any sources which support this statement? –  abcd May 27 '13 at 5:20
