Do you think ISO 22000 standard's practices are followed with their true spirit in industries irrespective of only external audit days?

I support the above answer would also say understanding, commitment and team work is what drives the system. Putting those words practically within is the challenge. Those who want to be in the right track will follow the system at all times irrespective of their mentalities.

ISO22000 give you a wide range of evaluation that the standards practices are followed or not, but the major factor is food safety culture in the facility, if there's a gap between the FSMS and management, the core business is going to be auto-degradation.
