I think headbands should be a MUST!
Everytime I watch, someone is sweating bullets into the food...YUCK!
Hygiene should be the number ONE priority. Maybe they should think about even wearing non-latex gloves.
So many times I have seen them wipe the sweat onto their sleeves. Guess that is better than their hand, but what about wipe towels? We have these at exercise classes, why not in the kitchen?
I'd freak-out if I was a judge and had to taste a sweat, dripping chef's dish.....ewwww.
