Hi ! I belong to the coconut oil manufacturing business. Our production facilties is "closed type" - meaning, the personnel never get to touch the materials to be crushed and cooked oil... they all flow in pipes (overhead/underground) and the goods are conveyed (through the same pipeline) from one food processing unit to another.
In this regard, do the production personnel have to follow the hand-washing, protective uniforms, etc. since they never get in contact with the product anyway?
Thanks for your help.
