I don't bite my nails and they are probably normal length, I do try and keep them rather short more because long ones get in my way lol. Anyhow, I had a friend who thougth she got sick from her nails, what it was is she made turkey, handled raw turkey and then I guess didn't wash her hands/nails well enough. I don't thinkt hat anyone should not have nails because of something like that tho. If you handle something you KNOW could be "bad" (like raw meat) scrub your nails and hands really well before handling anything else of putting your hands in your mouth. (common sense right?) It used to freak me out tho and I"d wash my hands then run q-tips w/ alcohol on them under my nails to be sure after handling meat. Anyhow, I hope this helps.
