I'm afraid I fall in the other end of the spectrum. Most of you apparently would not eat in my house!
My mother was a germ freak and made life miserable for everyone. NOt only couldn't I take a lick of someone's ice cream but i couldn;t even touch anything that had not been directly in contact with anything but was on the same dish because germs "crawl" across the dish - so if my brother touched something on his dish with his fork, i couldn't take another thing from his dish because it was all "contaminated". (Being in the same house and touching the same doorknobs would give me the same germs anyway unless i washed my hands every time i touched something or walked around like a surgeon with my hands up in front of me!)
Result, my brother, who was 6 yrs older and subject to a far more rigid sterilization policy, (if any kid played with his toy, it was put to sterilize! and he was not allowed to crawl except in the playpen!). When he started school at 6, naturally he got every disease in the book, including pneumonia, and was out for half of the first grade. My kids were hardly ever sick compared to others. They crawled on the floor, put their hands in their mouths, and i wasn;t washing them or the floor every ten minutes. And never, ever, sterilized something they put in their mouth. (The whole thing of sterilization was introduced because of bottle feeding and the MILK goes bad easily if the container isn;t sterile. It's not the contact with the germs that hurt the baby but drinking the milk that has been sitting, warm, in a non sterile container.)
If i taste something that's cooking, it's cooking for heaven's sake, and the heat will kill anything i can give it.
I'm not in a public kitchen. I'm home,. No police are coming to check.
A knife that cuts bread, a piece of fruit, a piece of carrot, or something that's not full of either grease or any contaminants that water won;t wash off is clean with water (soap doesn't remove bits of stuff attached, but rubbing does). If you were doing an experiment with a petri dish and making cultures of bacteria that would be a different thing. And maybe you can feel it's gross, which is a psychological thing, and fine, but it's not going to contaminate anything.
A board that's been in the dishwasher, i consider clean for all home purposes. It would never occur to me to use bleach on it or to scrub it any further.
Nobody's ever refused to eat in my house, and i don;t have a dining room, i do all my stuff in the same room as the guests are.
If someone uses a glass and just rinses it, that's a different story, though again, in the same household, i have no problem with drinking out of someone else's glass, since we are exposed a hundred times over to each other's germs from doorknobs, telephone, computer keyboards, surfaces, etc.
What comes in touch with saliva should be washed with detergent, but what comes in touch with a (presumably washed) piece of fruit or vegetable? Do you wash your fruit with soap? do you (as was indicated in another thread) wash your salad with soap??!!
