Rules for Walking and Bicycling

I haven't researched this yet, though I've been meaning to for years. My opinion has long been that walkers should follow the same rules of the road as cyclists. Obviously I don't mean they should walk on the street instead of using the sidewalk whenever available. What I do mean is that walkers and cyclists both should walk/ride in the same direction as traffic. My reasoning is thus: drivers on the road are conditioned to pay attention to their surroundings in very specific ways. When turning right onto a two way street, the driver typically only looks to those travelers moving in the same direction as he is; he pays more attention to what is happening on his left than he does to what is happening on his right. Turning left of course the driver has to look both ways, but turning right he is much less likely to. I have also argued that walking in the same direction on the same side of the road as traffic gives drivers much more opportunity to see the walker/rider than he otherwise might.

Susanne Pleshette, Fran Drescher, Helen Hunt and the USDA Food Safety Guidelines

I've mentioned each of the actresses above because I have seen each of them handle raw meat, wipe their hands on a dishcloth, and go on about other business on their respective television shows. My question is this: how long have the USDA food safety guidelines been in place.

I am really paranoid about handling raw meat in my kitchen. I run hot sudsy water in my kitchen sink before handling the meat; I wash the dishes and wipe down the counters that the meat has touched as soon as possible; I run fresh sudsy water to wash any remaining dishes. Because I never feel as though I have taken quite enough precautions I find myself often praying over my kitchen, "Oh God, please protect my husband and my son from my poor attempts at housekeeping."

So do these actresses wipe their hands on dishclothes due to television convention, or are hand-washing recommendations a recent development? The number of ads both on television and the radio indicate to me that they may be. Obviously I haven't researched this.
