Interview Questions for Certified Dairy Safety Manager

HACCP, or Hazard Analysis and Critical Control Points, is a preventative food safety system. In a dairy environment, it focuses on identifying potential biological, chemical, and physical hazards at each step of the production process, from raw milk reception to finished product packaging. The system then establishes critical control points (CCPs) – steps where control can prevent or eliminate a food safety hazard – and sets critical limits for each CCP. Monitoring, corrective actions, verification, and record-keeping are essential components to ensure the system’s effectiveness.

• Hazard Analysis: Identifying potential hazards like Listeria monocytogenes, Salmonella, E. coli, pesticide residues, and physical contaminants like metal fragments.
• Critical Control Point (CCP) Identification: Determining the steps where these hazards can be controlled or eliminated, for example, pasteurization (CCP for biological hazards), cleaning and sanitization (CCP for microbial control), and metal detection (CCP for physical hazards).
• Critical Limits: Setting measurable parameters for each CCP. For instance, a specific temperature and time for pasteurization or a maximum acceptable microbial count in finished product.
• Monitoring: Regularly checking CCPs to ensure critical limits are met. This might include temperature readings, pH measurements, or microbiological testing.
• Corrective Actions: Defining procedures to follow when critical limits are not met, potentially involving product rejection, reprocessing, or investigation into the root cause.
• Verification: Confirming the HACCP plan is effective through regular audits, reviews, and validation studies.
• Record-Keeping: Maintaining detailed records of all monitoring, corrective actions, and verification activities.

For example, in a cheese-making facility, pasteurization is a crucial CCP. If the temperature or time isn’t met, the cheese may not be safe, leading to potential foodborne illness outbreaks. The HACCP plan would outline procedures for dealing with such a failure, ensuring the affected cheese is removed from circulation.
