Hygienic Zoning in Food Processing: Core, Supplementary and Satellite

A hygiene zone is created within the facility based on the risk of contamination to a product. It’s designed to prevent pathogens from entering a facility or cross-contamination between production areas. There are three different types of hygienic zoning in food processing:

Core Hygiene Zone

This is the main hygiene zone at any facility where the majority of the staff are entering before going to the production area. This is the largest hygiene zone that the core of employees will pass through.

Supplementary Hygiene Zone

It may be within a core hygiene zone to provide additional hygiene steps specific to a staff member’s main function. For example a production team member may need a supplementary hygiene zone that is interwoven amongst the normal core hygiene zone process for donning thermals because they work in a cold storage environment most of the day.
