Overview
There is evidence of food/drink consumption in the areas where chemicals are used or stored.
Cite this when there is evidence of eating/drinking/utensils, etc. Auditors do not have to actually observe someone eating/drinking/washing dishes; the appearance of eating in the lab is enough “evidence” to cite this (e.g., wrappers in the trash, cups in the sink, eating utensils/dishes in lab dishwasher, etc.).
Sometimes, there will be laboratory tests/research conducted on foodstuffs. In those cases, the materials should be labeled as "Not for Human Consumption" or something equivalent.
Use of empty food containers for storage of chemicals is not recommended.
