Now, I read in a book... possibly 'Fast Food Nation'... that because of the dirty conditions in slaughter houses and the speed of the production line, meat-eaters end up with more fecal contamination in your kitchen sink than in your toilet bowl.
Classic misinformation.
true or not... think about what vegetables grown in. Always wash vegatables very well before you cook them.
Also remember that Vegatables are never generally cooked above 100C where are Meat tends to be cooked at around 200C.
Logic will prevail :-)
