I have been contemplating about doing HACCP Level 4 certification for quite some time now. While I don't see any disadvantages in this, the advantage that I see in it is it has no certification expiry and not change in version, unlike the ISO 22000 and FSSC 22000 standards and certifications.
Apart from getting the knowledge on how a robust HACCP system should be, are there any other advantages and disadvantages of HACCP Level 4 certification?
If you could let me know what is the scope of HACCP Level 4 and what is the way forward after that, I would be grateful to you. Please guide me.
