just a small interjection . . .
I had an extremely small "career" presenting the news on closed circuit TV during a military stint. I can vouch for the fact that making it all come off smoothly on the tube and getting all the other misc. details "right" is not as easy as one might think.
in my stint, there were no "do overs" - it was live. "nerves" is an issue - it did get 'easier' with time - learning to gracefully 'recover' from a bobble got easier, but I have no question about (a) looking non-flustered (b) presenting the recipes (c) the ingredients (d) the technique (e) the procedure (f) what the inexperienced may expect (g) what it looks like in the end . . . . etc etc is an order of some tallness.
frankly I don't know of a single home cook that dons gloves for food prep. well, mega-million Scoville hot peppers aside....
in a commercial kitchen - laws vary - but when was the last Typhoid Mary event?
cleanliness, hygiene, "good practices" all apply in any kitchen - but if I'm cooking up a pot of chile, yeah I double dip the spoon - more than once. but I do ditch the raw meat platter in the sink.
if I'm contagious, DW is gonna know about it - and likely not due to anything happening in the kitchen, we have other ways of establishing contagion . . . hence I don't have a lot of issues with TV personalities and their practices - they are not making NSF training films.
indeed I have QSis's reaction to the half-hearted scrape&dump - but WAIT there's more in the bowl - bit more frugal in that regard - but as my rant started out - TV is not real life.
