HACCP (Hazard Analysis and Critical Control Points) is a systematic food safety management approach that identifies, evaluates, and controls biological, chemical, and physical hazards throughout the production process, requiring preventive measures such as vibratory screening and metal detection at critical control points. Originally developed in the 1960s for NASA's space food program, HACCP is now the global standard for food safety and is required or recommended by the FDA, USDA, and international food safety authorities including Codex Alimentarius.
The HACCP system is built on seven principles: conduct a hazard analysis, determine critical control points (CCPs), establish critical limits, establish monitoring procedures, establish corrective actions, establish verification procedures, and establish record-keeping. For physical hazard control, vibratory screening is one of the most common CCPs in food processing. A vibratory screener at the raw material receiving stage, at intermediate process points, or before packaging catches foreign objects such as metal fragments, glass, plastic, insects, hair, string, and agglomerates that could endanger consumers.
HACCP Seven Principles and Screening Relevance
| HACCP Principle | Description | Vibratory Screening Role |
|---|---|---|
| 1. Hazard Analysis | Identify physical, chemical, biological hazards | Physical hazards (metal, glass, foreign objects) are screening targets |
| 2. Critical Control Points | Determine points where hazards can be controlled | Screening and metal detection are common CCPs |
| 3. Critical Limits | Establish measurable limits at each CCP | Mesh size is the critical limit for screening CCPs |
| 4. Monitoring | Establish procedures to monitor CCPs | Screen inspections, oversize checks, screen integrity testing |
| 5. Corrective Actions | Actions when monitoring shows CCP out of control | Screen replacement, product hold and rescreen, root cause analysis |
| 6. Verification | Confirm HACCP system is working | Sieve analysis of finished product, screen verification records |
| 7. Record-Keeping | Document all HACCP activities | Screen change logs, oversize rejection logs, mesh verification records |
Why This Matters in Vibratory Screening
HACCP compliance is a non-negotiable requirement for food processors, and vibratory screening is at the center of physical hazard control in nearly every HACCP plan.
- Critical control point — Vibratory screeners serve as CCPs where physical hazards are removed from the product stream. The screen mesh size is the critical limit, and any deviation (torn screen, wrong mesh, bypassed screener) is a HACCP deviation requiring corrective action.
- Audit readiness — Food safety auditors (SQF, BRC, FSSC 22000) evaluate vibratory screeners as part of HACCP verification. They look for documented screen change schedules, mesh verification records, and evidence that screens are inspected before and after each production run.
- Equipment design requirements — HACCP programs require that screening equipment be designed for food safety: sanitary construction, easy cleaning, no product entrapment areas, and food-grade materials. ScreenerKing's 304 SS and 316 SS screeners and pre-tensioned screens are designed to meet these requirements.
- Layered protection — A thorough HACCP plan pairs vibratory screening with magnetic separation and metal detection to address physical hazards that a screen alone cannot catch.

HACCP FAQs
What is HACCP?
HACCP (Hazard Analysis and Critical Control Points) is a systematic food safety approach that identifies potential hazards and establishes critical control points where those hazards can be prevented, eliminated, or reduced to safe levels. It is the global standard for food safety management, required or recommended by FDA, USDA, and international food safety bodies.
How does vibratory screening relate to HACCP?
Vibratory screening is a primary physical hazard control measure in HACCP plans. Screens remove foreign objects, oversize contaminants, and agglomerates at critical control points. A vibratory screener at ingredient receiving or pre-packaging is one of the most common CCPs, often paired with magnetic separators and metal detectors for comprehensive protection.
What mesh size should I use for HACCP screening?
The mesh size depends on your product and hazard analysis. The screen must be fine enough to catch identified physical hazards while passing conforming product. For safety screening, a mesh 2-4 sizes coarser than your product's largest acceptable particle is typical. ScreenerKing's technical team can help you determine the correct mesh size for your HACCP critical control point.
