What is HACCP?
HACCP (Hazard Analysis and Critical Control Points) is a preventive food safety management system that identifies, evaluates and controls the significant hazards to food safety throughout the entire production process, instead of relying solely on finished product inspection.
The 7 principles of HACCP
The system is classically structured around seven principles: (1) conduct a hazard analysis, (2) determine the critical control points (CCP), (3) establish critical limits for each CCP, (4) establish a monitoring system, (5) establish corrective actions, (6) establish verification procedures, and (7) establish a documentation and record-keeping system.
Where does microbiological analysis fit within HACCP?
Microbiological analysis mainly plays a verification role within HACCP: it confirms that the CCPs and the prerequisite programs (cleaning, pest control, training) are effectively reducing microbiological risk to acceptable levels. Environmental surface sampling is usually part of the verification program in plants handling pathogens such as Listeria monocytogenes.
HACCP vs. GFSI schemes (BRC, SQF, FSSC 22000)
HACCP is a technical system, not a certification in itself. GFSI-recognized schemes (BRCGS, SQF, FSSC 22000, among others) take HACCP as their basis and add further requirements for management, traceability and food safety culture, and they are certifiable by a third party.
Common mistakes when implementing HACCP
- Defining too many CCPs, diluting the focus on the truly critical ones.
- Not revalidating the plan when a formulation, supplier or production line changes.
- Treating monitoring as an administrative record instead of a real early warning.
Conclusion
HACCP structures food safety management around prevention rather than final inspection, and microbiological analysis is the tool that verifies, with real data, that this preventive system is working.

Frequently asked questions
Is HACCP mandatory?
In many countries it is mandatory for certain food categories (for example, meat and seafood products in the USA), and it is a de facto requirement for access to most export markets.
What is the difference between a CCP and a prerequisite program (PRP)?
A CCP controls a specific hazard that, left uncontrolled, would result in an unacceptable risk; a PRP (cleaning, pest control, training) creates the baseline conditions for the HACCP system to work, but does not control a specific hazard on its own.
How often should a HACCP plan be revalidated?
At least once a year, and whenever anything relevant to the process, formulation, equipment or suppliers changes.
