I heard about this as well, but I question how much more likely you are to getting sick from the purported cross contamination vs. not washing it, since most people will still be handling the chicken a lot any how and touching other utensils and such. Not to mention the chicken itself comes with a lot of juice that drips all over the place anyhow. By the time I cut the plastic wrapping off of a whole chicken or take the chicken parts out of their container, there is chicken juice everywhere to begin with and I am reaching for the sink constantly to keep rinsing my hands off anyhow.
I think if you just use some common sense and don't directly handle other utensils and bowls and pans right after touching the raw meat, as well as not being a klutz and carrying the meat with dripping juices over kitchen gear that you plan on handling raw food with afterwards, you can avoid a lot of trouble. Not to mention if you really want to play things safe, just prep everything else and save the chicken handling for last.
