Hazard Identification and Contamination Pathways
Identifying biological, chemical, physical and allergenic hazards with specific source, cause, manifestation, step and affected product.
How to prepare for Level 3 HACCP
Move from recognising the seven principles to analysing an evidence-led plan, responsibility boundaries and the proof needed to keep people, process and product under control.
Core concepts
Concept 1
biological hazards including contamination, survival, growth and toxin formation
Exam cue: Write the specific hazard, source or cause and possible manifestation at the actual process step.
Concept 2
chemical hazards including residues, cleaning chemicals, toxins and formulation errors
Exam cue: Follow the pathway from introduction or survival to exposure of the intended consumer.
Concept 3
physical hazards from materials, equipment, environment and people
Concept 4
allergenic cross-contact and incorrect ingredient or label information
Risk pitfalls and guardrails
Writing only a broad category such as bacteria, chemicals or foreign bodies.
Guardrail: Do not universalise provider assessment facts, copy an unsupported plan value, overclaim management authority, call every control a CCP, release uncertain product or confuse validation with verification.
Treating spoilage, quality defects and food-safety hazards as interchangeable without assessing harm.
Guardrail: Do not universalise provider assessment facts, copy an unsupported plan value, overclaim management authority, call every control a CCP, release uncertain product or confuse validation with verification.
Memory anchors
Specific hazard statement
Agent or condition, source or cause, process step and possible consumer harm.
Biological pathway
Introduction, survival, growth, toxin or recontamination as applicable.
Chemical pathway
Presence, mis-dose, migration, residue, natural toxin or unintended contact.
Physical pathway
Material fragments can enter from ingredients, equipment, premises, packaging or people.
Allergen pathway
Ingredient identity, segregation, scheduling, cleaning, rework, label and communication.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

A hazard table lists only 'bacteria' at raw chicken receipt. Which revision is most useful?
Fine metal fragments could enter a sauce when a worn mixer blade contacts its housing. How should the hazard be described?
