Here are a couple of lists that might be helpful.

http://www.woodturner.org/resources/toxicity.cfm
http://www.thewoodbox.com/data/wood/toxicityinfo.htm
http://www.awwg.org/awg_woodtoxicity.htm

OK, so I can't count (that is more than a couple). Hope these sights help.
More available by searching "wood toxicity" on the web.

Red Oak.

Red oak is porous - liquids would leak out, and you'd have a hard time
cleaning the food out of the tiny holes. You'd need a finish that
would fill the pores, and then you have to worry about the finish too.

Now white oak - they make wine barrels out of that, so it "must be
safe" to use :-)
