I'm not a professional chef, but I think someone will have this issue, somewhere, and is a chef. A similar question asked about having a cold, but nail biting is much worse due to the obvious amount of cuts one develops on fingers.
Apart from the obvious (and difficult to achieve) goal of stopping the habit, how can I maintain proper hygiene and food safety while cooking?
I would say gloves, but I think it's going to be a problem for complex manipulations, and it could affect the taste of what is prepared. Is there a special brand specifically for this purpose? If not, what other precautions can I take?
