I have a two part question on flow diagrams for HACCP;
- I am seeing many definations of what is considered a "process step" for doing a flow chart for HACCP. I have come to the conclusion that a process step includes anything that could introduce a hazard (biological, chemical or physical). This does not include tests or decisions made. I am trying to make this defination as logical as possible for the HACCP team to identify process steps and not go overboard. What is everyone's opinion on a process step?

- Also, conveyor belts, do you put these in your flow diagram? I say no.

A couple of interesting questions. Firstly a process step could be described a simply a stage in the process.
Hazards can be introduced at many stages but may be controlled by GMP or Prerequisite Programmes.
Taking the conveyor as an example, there may be many modes of transfer of product in an operation, but would they all be in the flow diagram?
Effective
HACCP implementation requires you to put in place fundamental food safety/GMP procedures so that the Hazard Analysis and final plan are not over complicated.
To quote CODEX Recommended International Code of Practice General Principles Of Food Hygiene:
Where necessary, conveyances and bulk containers should be designed and constructed so that they:
- do not contaminate foods or packaging
- can be effectively cleaned and, where necessary, disinfected;
- permit effective separation of different foods or foods from non-food items where necessary
Conveyances and containers for transporting food should be kept in an appropriate state of cleanliness, repair and condition. Where the same conveyance or container is used for transporting different foods, or non-foods, effective cleaning and, where necessary, disinfection should take
place between loads.
Prior to application of HACCP to any sector of the food chain, that sector should have in place prerequisite programs such as good hygienic practices according to the Codex General Principles of Food Hygiene, the appropriate Codex Codes of Practice, and appropriate food safety requirements. These prerequisite programs to HACCP, including training, should be well established, fully operational and verified in order to facilitate the successful application and implementation of the HACCP system.
So your conveyors should be covered by GMP and as such I would not put them in the flow diagram as this is also part of the application of the
HACCP system. As an example in one of my previous roles Listeria contamination from conveyors was a potential hazard and as such we had GMP Cleaning/Sanitation and Monitoring Procedures to control Listeria such that the risk to the product was not significant.
Some posters have mentioned "equipment" which may be in the flow diagram especially if it has a function like inspection which identifies and removes hazards.
Some people knock ISO 22000 but IMO it does include a review and updating requirement after Hazard Analysis and implementation of the system which is no bad thing.

Tony
