How to determine cross-contamination area?

Good day everyone, I am drawing our plant schematic form 4 for our HACCP plan, can anyone share any technique/tips how to determine cross-contamination area on form 4? Thanks.

you need to 

A) watch flow on the floor

B) put your arrows on the form 4 for people/ingredients/finished goods/maintenance/qc/waste etc

voila, where the lines cross, those are your cross contamination points        particularly where clean/dirty paths cross and allergen movement (if applicable)

Hi Scampi,

This is surely a unique haccp requirement !! ?

But is the requirement a point or an area ? As the Walrus said to the Carpenter..

In Canada we are required to show a process flow (federal requirement)  CFIA is most used to seeing it this way and it will allow the auditing process to go smoother

Whether it is a point or an area will be evident on a well done process flow as you should also be showing allergen flow--so if you're allergen flows from 1 area to another area, the areas would be CC zones........if allergens flow from the warehouse (CC area) to mixing , then the mixing point would also be a CC point

Hard to explain without seeing the diagram

CFIA follows traditional CODEX HACCP with a few additional requirements thrown in
