Quick answer
A food-safety hazard is something in food or its handling that could harm the person eating it. Consider microbiological, chemical and physical hazards, and make allergens explicit in the assessment. Different systems may group allergens differently, but they must not disappear from the controls. Identify the actual hazard before deciding how to manage it.
A useful label leads to a specific control
Calling a problem “contamination” is only the start. Harmful bacteria, a cleaning-chemical residue and a piece of broken plastic require different responses.
CookSafe explains hazard categories and control measures. Official management guidance connects the food-safety system with the real business, including allergen control.
Recognise the practical differences
| Type | Example | Control question |
|---|---|---|
| Microbiological | Harmful organisms transferred from raw to prepared food. | How is contamination prevented and any relevant kill step checked? |
| Chemical | Unsuitable chemical use or residue. | Are products, storage and use instructions appropriate? |
| Physical | A broken plastic part reaches food. | How are equipment condition and contamination incidents controlled? |
| Allergen | An undeclared ingredient or unintended allergen transfer. | How are information, changes and preparation managed? |
The examples are prompts rather than a complete hazard analysis. Some systems consider allergens within chemical hazards; others give them a separate heading. Choose clear documentation that covers them properly.
Distinguish the hazard from the risk
The hazard is the potential source of harm. Risk considers how likely harm is in the particular circumstances and how serious it could be. The same ingredient can be handled in processes with very different controls and customers.
A raw-poultry ingredient is not made safe by giving it a “high risk” label. Identify the route, such as packaging contact with sandwich equipment, and choose an effective control. A category alone does not tell a worker what to do.
Look at each step and intended use
Review purchasing, storage, preparation, cooking and later handling through to service or delivery. Include equipment, packaging, people and the food’s intended use. MyHACCP’s product-description stage explains why ingredients, physical properties, packaging and shelf life affect the analysis.
Some controls apply across the operation, while others belong to a particular product or critical process. Use competent help if a specialist activity exceeds the business’s knowledge.
Worked example: a replacement sauce brings several questions
Hypothetical example: a supplier substitutes a sauce. Staff check its date but do not check the changed ingredients or storage instructions.
The manager reviews relevant allergens, after-opening storage and any preparation changes before use. This single change may affect more than one hazard category. Updating only the stock number would leave those practical questions unanswered.
Write controls and failure actions clearly
For each significant hazard, state what prevents or reduces it, how the control is checked and what happens if it fails. Protect affected food while suitability is established; do not hide uncertainty behind a generic tick box.
Review after changes and failures. Keep detailed allergen information and procedures in the allergen system, supported by the practical allergen guide.
Next steps
Choose one real dish and identify its hazards step by step. Write the controls in language staff can use, then check their effectiveness with a documented review.
