I've been feeding raw about 2 years now and I'm not overly careful, just basic about cleaning up after it. Honestly, I don't care if my boys give me a kiss 5 mins after they eat. It's just never been an issue for us - we've never had a problem w/ us or the boys getting ill from raw. I don't clean their beards or anything either, as they don't get messy.
You just have to find out what is comfortable for you.
