I recently came into possession of a wonderful turned maple bowl however there is one downside. There is a small crack about halfway through the bowl. The crack goes fully from top to bottom but not fully left to right. The bowl is not about to fall apart but I think after a while of putting fruit into it, or several used as a salad serving bowl the crack would spread and weaken. 

Is it possible to glue this and (bonus points) glue it with a food safe glue?
