FOOD-SUP-3.1.1

The Seven Principles, the Twelve Steps and the Flow Diagram

Sets out the seven HACCP principles and the twelve logical steps of a HACCP study, and shows how to build and confirm a flow diagram for a yacht's food operation, including water, ice and the tender transfer. Introduces hazard analysis with a worked table.

Management has asked for the vessel's HACCP plan before the summer charter season. What exists is a laminated sheet of fridge temperatures and a chef who says "we know what we are doing". The reason HACCP is structured as twelve steps is that skipping the first five is exactly how plans end up describing an operation that does not exist.

The seven principles

# Principle
1 Conduct a hazard analysis
2 Determine the critical control points (CCPs)
3 Establish critical limits for each CCP
4 Establish monitoring for each CCP
5 Establish the corrective action when a limit is breached
6 Establish verification procedures
7 Establish documentation and record-keeping

The twelve logical steps

Steps 1-5 are preparation; steps 6-12 apply the seven principles.

Step Action On a yacht
1 Assemble the HACCP team Chef, chief stew, purser/ETO, captain as sponsor
2 Describe the product Crew meals, guest menus, canapés, sushi, beach service, ice, drinking water
3 Identify intended use and consumers Guests including children, pregnant and elderly; crew. Vulnerable groups matter
4 Construct the flow diagram Every step from provisioning to service and waste
5 Confirm the flow diagram on site Walk it physically — the written flow is always optimistic
6 Hazard analysis (P1) Biological, chemical, physical, allergenic at every step
7 Determine CCPs (P2) Use a decision tree
8 Set critical limits (P3) Measurable and justified
9 Monitoring (P4) What, how, when, who
10 Corrective action (P5) For the food and for the cause
11 Verification (P6) Is the plan working, and is it still right?
12 Documentation (P7) Records that prove control

Building the flow diagram for a yacht

A generic restaurant flow will not survive a yacht. Yours must include the steps that are uniquely yours:

Supplier selection → order → delivery to quay → tender/launch transfer → acceptance check → storage (dry/chill/freeze) → thaw → preparation → cooking → cooling → chilled storage → reheating → hot holding → plating → transport ashore → service → leftovers → waste

Add the parallel flows most plans forget: potable water bunkering → tanks → ice machine → drinks and washed produce, and the crew mess as a separate product with its own bulk-cooking and cooling risks.

Hazard analysis

At each step ask: what could go wrong here (biological, chemical, physical, allergenic), how likely is it, how severe would it be? Then name the control measure.

Step Hazard Type Significance Control measure
Tender transfer Growth from cold-chain break B High Insulated boxes; time limit; temperature on arrival
Bulk cooling (crew stew) C. perfringens spore germination B High Rapid cooling; portion small
Cleaning during service Chemical residue C Medium No spraying during service
Canapés Undeclared nuts A High Allergen matrix and verification

Onboard Notes

  • Walk your flow diagram physically before you sign it. What crew actually do is the plan you have, whatever the folder says.
  • Do not copy another boat's HACCP plan. A plan that does not describe your galley is documented evidence that you did not look.

Scope note: xplor is not an approved centre or an accredited training provider. This lesson is preparatory study only - no certificate and no regulated qualification is awarded here, and a Level 3 supervising food safety award must be sat and assessed with an approved centre of a regulated awarding organisation.

Your HACCP plan flow diagram was written by a previous chef three years ago. You walk the galley to confirm it. What are you actually doing, and what kinds of discrepancy would you expect to find?

What is a hazard analysis, and how does it differ from simply listing hazards?

Independent study. xplor is not an Ofqual-regulated awarding organisation or an approved centre, and awards no qualification. Useful preparation if you are working toward a Level 3 supervising food safety award, which must be sat with an approved centre.
