Food additive

 is a miscellaneous item in Fallout: New Vegas.

Characteristics
A food additive meant for Cpl. William Farber (the cook) in Camp McCarran.

Found in Vault 22. When exiting the elevator on the Food Production level, make your way down the main hallway and enter the last hallway on the left before the main hallway turns right. Enter the first room on the left and walk to the back where there is a small office-like room with spores growing in front of the desk. The food additive is sitting on the top of the desk.
