I am concerned about safe food practices. On several occasions I have witnessed the man on the grill sans gloves whilst handling food and cross contaminating. Raw meat being thrown on the grill and subsequent handling of cheese, onion, pickle, bun, etc. On the occasion I have seen him donning gloves, I have witnessed him going into his pocket with said gloved hand and using his phone and then right back to cook/prep with same gloves. This behavior has been brought to light by several other colleagues as recent as yesterday while grilling in the courtyard. The next occasion I witness this I will be in contact with the local board of health. This is absolutely unacceptable.
