A category of "Professional Cook" "Food Prepreration Worker" both positions need to have ServSafe Foodhandler Certification.

Disaster workers need to eat. Disaster field kitchens need certified workers and cooks. Additionally, small communities may have a community kitchen in a park that could be utilized if certified food service workers were available.
There is too much liability to accept food from someone's home, and or to have a non-certified person prepare food for people. This is true nation wide.
For a certified cook this person should have at least a ServSafe Foodhandler Certificate. For a certified food Prepreration volunteer they must possess a ServSafe FoodHandler certificate as well.
