When I taught cooking in my high school, the girls in the kitchens were taught to 'taste' with a spoon which was then put immediately into a glass filled with soapy water, which sat prominently on the counter. Then if a second taste was needed, a clean spoon was used and deposited again, immediately into the soapy glass. Routine once followed prevented any 'double dipping'. Hands, which came in contact with food, were washed and dried on clean towels (not on aprons or just wiped off on a dirty dish towel). I'm wondering how many of my students still follow that routine today.
I still shudder to think what happens in the kitchens of my local restaurants where no one is really watching. My all time favorite 'shudder moment' is when I asked for my very sticky table at my favorite diner to be wiped off, and I watched in horror as the busboy took a soppy wet rag out of a bucket, wrung it out and then wiped my table, then deposited the rag back into the bucket, probably to be used again and again. WHAT was possibly on that rag from all the tables (and who knows what all else it touched) still haunts me.
