human beings
are 70%+ bacteria by weight. My degrees are in Biology and BioChemsitry, worked for Baltimore County Dept of Health in Food Facilities Inspection (restaurants, food processing and manufacturing, &c) for 6 years after college and before teaching Bio, and responsible for investigating outbreaks of food borne illnesses. There's way too much paranoia about bacteria, to the point that overuse of antibiotics, in animal feeds, household products, liquid dishwashing soaps, &c have caused major bacterial resistance to most antibiotics, a big problem. Yes, some common sense is required in washing stuff, yes, pathogenic bacteria like Eschericia Coli, Staphloccus Aureus, Clostridium Perfringens, Vibrio Haemolyticus, Shigella, Pseudomonas, Salmonella, and others, require some degree of caution and avoidance, mostly just simple procedures. Restaurants are required to sanitize by corrrect use of dish machines or handwash, rinse and sanitize with chemicals. Simple disinfection of any food prep surfaces with 10% bleach will kill about anything, that's what hosptials do, and use of a little bleach in the washing machine with correct temperatures is easy and effective. The article linked to is a good one, but people do tend to get carried away when thinking negatively about bacteria in general. The latest medical advice is when a baby drops that pacifier on the floor, Mom should pick it up, suck on it, and hand it back. Systemic immunity to bacteria is developed by exposure, not by sanitizing everything in sight, and avoidance of the really bad ones is not all that difficult.
