There are a number of web sites that present such implicit and procedural knowledge. such as: http://www.ehow.com/ http://www.wikihow.com/Main-Page http://www.howcast.com/ http://www.howtodothings.com/
I might be useful to somehow select the most generally useful ones of these in one place.
Generally, it is mainly chicken that one needs to be careful about, because it is sometimes contaminated with unhealthy bacteria, even when bought “fresh”. A general procedure with all meat, and especially chicken, is to wash any surface that raw chicken comes in contact with when you are done preparing it and have started to cook it, then wash any utensils you used that touched the chicken, and wash you hands. To be extra cautious, you can do that for any raw meat. Raw meat should be refrigerated soon after purchase and now allowed to stand uncooked at room temperature for more than the time it takes to prepare it.
