How to Record a Cooking Shellfish Safely Video for Your Food Safety Management System

Shellfish—crustaceans and molluscs—require extra care during storage, handling, preparation and serving. The risks are significant: bacteria can survive in shellfish left at ambient temperatures and can also survive when shellfish are undercooked. Dead shellfish can cause food poisoning if consumed. This video will train your team to handle shellfish safely throughout the chain—from delivery acceptance and live storage through viability checks, preparation, and service.

Step 1: Set the scene and context

Start your video by explaining why shellfish needs dedicated procedures and what makes them different from other proteins. This context helps staff understand they're managing living products that deteriorate rapidly and can cause serious illness.

Shellfish will require extra care during storage, handling, preparation and serving and steps must be taken to ensure that they do not present a risk to consumers. Unlike other proteins, many shellfish are kept alive until preparation—dead shellfish can produce toxins and contaminate other shellfish.

Explain the unique challenges of shellfish:

• Live shellfish must stay alive until cooking or serving
• Dead shellfish can cause food poisoning if consumed
• Storing shellfish in water (fresh or salt) is harmful
• Temperature control is critical—bacteria survive at ambient temperatures
• Health ID tags are legally required for traceability

Staff must follow strict safety points to ensure a consistent level of food safety is maintained. The consequences of shellfish mishandling include serious illness and regulatory action.

Film your opening in your shellfish storage area or at your delivery acceptance point, showing your storage setup and any live shellfish you handle.

Step 2: Plan what to record versus what to write down

Shellfish safety involves both visual demonstration of handling techniques and documentation of supplier relationships and traceability. The video shows the techniques; the written documents provide the evidence trail.

Record on video:

• Delivery acceptance procedure (temperature, ice, tags, shelf life)
• What health ID tags look like and why they matter
• Correct storage setup (perforated gastronorm method)
• Why shellfish must never be stored in water
• Live mussel viability check (the tap test)
• Live oyster viability check (tightly closed, juice inspection)
• Complete oyster opening procedure with correct technique
• Shell scrubbing and preparation
• Service fridge management with minimal quantities
• What colour and texture changes to look for during cooking
• When to discard shellfish

Document in written procedures:

• Your approved shellfish suppliers and their HACCP credentials
• Delivery acceptance criteria checklist
• Health ID tag retention requirements and storage location
• The 2-day shelf life rule from delivery
• Temperature monitoring records
• Corrective actions for non-compliant deliveries
• Discard log for spoiled or suspect shellfish
• Training records

The video shows HOW to handle shellfish safely. The written documents provide traceability and evidence of compliance.

Step 3: Core rules and requirements

Structure your video around the critical elements of shellfish food safety, including the complete fresh mollusc policy.

Supplier requirements

Shellfish must only be purchased from reputable and approved suppliers only. All packages of live shellfish must be delivered with the health/ID tags. The tags and delivery notes must be retained for the purposes of due diligence and traceability.

Reputable approved suppliers of shellfish should provide written assurances that products have been handled and stored correctly and products have been harvested from approved beds/areas only.

Ensure the date of delivery is recorded to allow you to trace a particular delivery if and when required. This traceability is essential if illness occurs—you must be able to identify exactly where affected shellfish came from.

Delivery acceptance

The fresh mollusc policy specifies strict delivery requirements:

1. Check the temperature of the products upon delivery—this must not exceed 5°c. The products must be covered in ice.
2. There must be sufficient shelf life available on the products otherwise refuse delivery.
3. The shellfish must be accompanied by their tags at all times. Check delivery notes against the tags and keep all paperwork together.
4. Do not accept delivery if the above conditions are not met.

These are non-negotiable requirements. Shellfish arriving above temperature, without adequate ice, or without proper documentation must be refused.

Live shellfish storage

Live clams, mussels and oysters must not be stored in water or in an airtight container in the fridge. The container must be dry and well ventilated.

The reasons are critical:

• Storing shellfish in fresh water will kill them
• Storing in salt water will shorten their shelf life
• Dead shellfish can contaminate live shellfish
• Dead ones can produce toxins which can be released into water contaminating other molluscs

Do not sit molluscs in any water, fresh or salted.

The perforated gastronorm method

Storage should be achieved by sitting products in a perforated gastronorm covered in ice. This container in turn is sat in a larger gastronorm. Melt water from ice can drain through the smaller perforated container into the larger container keeping the products safe.

This setup keeps shellfish cold (on ice) while ensuring they never sit in water (meltwater drains away). The melt water must be removed regularly to avoid molluscs sitting in melt water.

The 2-day shelf life rule

Follow the production date labelling procedure—giving the products a 2-day shelf life from day of delivery, then discard if unused. Ensure the cold chain has been maintained through the two days of storage at a maximum of 5°c, but preferably below.

These products must not be frozen under any circumstances. They must be kept on ice and checked regularly.

Live viability checks

Mussels: Ensure that mussels are checked on receipt from the supplier—dead mussels can cause food poisoning if consumed. Discard any dead ones. Check mussels when preparing them: mussels that do not close when tapped and any mussels that remain closed after cooking must be discarded.

Oysters: Check each oyster during preparation, ensuring that they are tightly closed. Also ensure that any oyster juices do not contain any blood or look milky in colour. Discard any dead oysters as consumption can cause food poisoning.

All molluscs must be tightly closed. Any open ones must be discarded. If unsure then it is safer to discard them.

Service and cooking

Shellfish should only be removed from refrigerated storage immediately prior to serving, only removing the required number of shellfish at any one time.

Bacteria can survive in shellfish left at ambient temperatures and can also survive when shellfish are undercooked. Ensure that shellfish such as mussels and prawns change colour and texture during the cooking process.

Do not leave molluscs at room temperatures, apart from a quick turnaround to service when preparing them.

Service fridge management

Temperatures of service fridges can rise during busy periods. To avoid problems with molluscs, only hold minimal amounts of product at any one time within these fridges. Only place the molluscs in the fridge 30 minutes before they are needed.

When molluscs are held in service fridges they should be held in suitable watertight containers and kept cold using ice packs above and below (you can use gel packs supplied with fish).

Any molluscs that have been kept in glass display fridges can only be used for hot cooked dishes.

Pre-cooked shellfish

Using pre-cooked shellfish can reduce the risk of food poisoning. They must only be supplied by approved suppliers with robust HACCP procedures in place. These products must be stored correctly following manufacturer's instructions strictly. They must be reheated to correct temperatures and temperatures checked before serving.

Step 4: Demonstrate or walk through

This is where you show staff exactly what safe shellfish handling looks like.

Delivery acceptance demonstration

Show the complete process:

"A shellfish delivery has arrived. I'm following our fresh mollusc policy step by step."

"First, temperature. Check the temperature of the products upon delivery—this must not exceed 5°c. I'm probing between packages: 3°c. Acceptable."

"Ice check. The products must be covered in ice. Yes—substantial ice coverage, not just a few cubes on top."

"Tags. The shellfish must be accompanied by their tags at all times. Here are the health ID tags—one for each batch. I'm checking delivery notes against the tags. They match."

"Shelf life. There must be sufficient shelf life available. These mussels were harvested yesterday—two days' shelf life from today is acceptable."

"Everything checks out. I'm accepting this delivery. If any of these conditions weren't met, I would refuse—do not accept delivery if conditions are not met."

Rejecting a delivery demonstration

Show what refusal looks like:

"This delivery has problems. Temperature reads 7°c—above the 5°c limit. The ice has mostly melted."

"Do not accept delivery if conditions are not met. I'm refusing this delivery and documenting the reason."

"Inform head chef if supplier does not follow strict protocols regarding delivery—temperature, transit conditions, use by dates, health ID tags."

"Review supplier if strict protocols for delivery are not met. This isn't a one-off—repeated failures mean finding a new supplier."

Tag and paperwork retention

Demonstrate the documentation:

"I've accepted the delivery. Now I'm keeping the paperwork together."

"The tags and delivery notes must be retained for the purposes of due diligence and traceability. These go into our shellfish documentation folder."

"I'm recording the date of delivery to allow tracing of this delivery if and when required. If a customer becomes ill, I can identify exactly which batch they consumed and where it came from."

Storage setup demonstration

Show the correct method:

"Now I'm setting up proper storage. Live clams, mussels and oysters must not be stored in water. The container must be dry and well ventilated."

"I'm using the perforated gastronorm method. Here's a perforated gastronorm—see the holes in the base. This sits inside a larger solid gastronorm."

"I'm placing ice in the bottom of the perforated container, then the shellfish on top, then more ice covering them."

"Melt water drains through the perforations into the larger container below. The melt water must be removed regularly—I'll empty that bottom container several times a day."

"Storing shellfish in fresh water will kill them. Storing in salt water will shorten their shelf life. Dead shellfish can contaminate live shellfish. This method keeps them cold without water contact."

Why water kills shellfish

Demonstrate the principle:

"Why is water so dangerous? Let me explain while showing you the setup."

"Do not sit molluscs in any water, fresh or salted. Fresh water kills them outright—their bodies can't handle the osmotic shock."

"Salt water seems logical, but dead ones can produce toxins which can be released into water contaminating other molluscs. One dead mussel contaminates the whole batch."

"That's why we use ice with drainage. Cold temperature, no water contact."

Mussel viability check

Demonstrate the tap test:

"I'm preparing mussels for service. First, the viability check."

"Ensure that mussels are checked—dead mussels can cause food poisoning if consumed."

"I'm sorting through the batch. This mussel is open. I tap it on the counter. Watch—did it close? Yes, it's closing slowly. This mussel is alive, safe to use."

"This one is open too. I tap it. No response. Tapping again. Still open. Mussels that do not close when tapped must be discarded. This one goes in the discard container."

"I'm checking every mussel in the batch. Any that don't close when tapped are discarded."

Post-cooking mussel check

Demonstrate the second check:

"The mussels have cooked. Now I check again."

"Any mussels that remain closed after cooking must be discarded. See this one? Still tightly shut while all the others have opened."

"A mussel that doesn't open during cooking was likely dead before cooking, or there's something wrong with it. I'm removing it from the dish."

"Every closed mussel after cooking gets discarded. No exceptions."

Oyster viability check

Demonstrate the inspection:

"I'm checking oysters before opening. Check each oyster during preparation."

"First: ensuring that they are tightly closed. This oyster is shut tight—I can't see any gap. Good."

"This one has a slight gap. I'm pressing it closed. Does it stay? No, it springs open. Discard any dead oysters as consumption can cause food poisoning."

"Tightly closed oysters only. Any with gaps that won't stay closed are discarded."

Complete oyster opening procedure

Demonstrate the full technique:

"I'm opening oysters for service. Oysters must only be opened on demand—they must never be opened in advance and held in a fridge."

"Step 1: Only an oyster knife must be used for opening. No other type of utensil must be used. This is my oyster knife—short, sturdy blade with a guard."

"Step 2: Ensure that oysters are tightly closed. If not, they must be discarded. I've already checked this batch."

"Step 3: The outside surface of the oyster shell should be scrubbed with a brush before serving. I'm scrubbing under cold water with this brush—a red nail brush should be allocated for this task."

"Step 4: Place the appropriate chopping board onto the bench. Secure the chopping board and rest the oyster round side down onto a cloth to prevent the oyster slipping when opening."

"Step 5: Place the point of the oyster knife into the joint of the shell at the pointed end. Taking extreme care, push the knife into the joint and twist the knife slightly to pop open the oyster."

"Step 6: Once opened, discard the top part of the shell and remove any broken shell particles."

"Step 7: Gently prise the oyster off the shell, then place the oyster back onto the shell."

"Step 8: Check that the oyster juices do not look milky in colour or contain any blood. Clear juices—good. Milky or bloody—discard."

"Step 9: Serve the oysters immediately after they have been checked. Not 'in a few minutes'—immediately."

Shell preparation demonstration

Demonstrate thorough cleaning:

"Before serving any molluscs, the shells must be scrubbed. A red nail brush should be allocated for this task."

"I'm scrubbing each mussel under cold running water. Any barnacles or beards must be removed before serving these products."

"See this fibrous 'beard' hanging from the shell? I'm pulling it off firmly toward the hinge end of the mussel."

"Barnacles get scraped off with the back of a knife. The shell should be clean and smooth before cooking."

Service fridge management

Demonstrate the minimal quantity principle:

"I'm preparing for service. Temperatures of service fridges can rise during busy periods."

"To avoid problems with molluscs, only hold minimal amounts of product at any one time. I'm taking only what I need for the next 30 minutes."

"Only place the molluscs in the fridge 30 minutes before they are needed. Not hours ahead—30 minutes."

"When molluscs are held in service fridges they should be held in watertight containers and kept cold using ice packs above and below. I'm placing gel packs above and below these oysters."

"The bulk of my shellfish stays in the main storage on ice. I take small quantities to service as needed."

Glass display fridge rule

Demonstrate the restriction:

"These mussels have been in the glass display fridge for the seafood display. Any molluscs that have been kept in glass display fridges can only be used for hot cooked dishes."

"Display fridges fluctuate more than standard fridges—customers looking, doors opening, display lighting warming the products."

"These cannot be served raw. They must be thoroughly cooked. I'm setting them aside for the moules marinière."

Cooking verification

Demonstrate the visual checks:

"These prawns and mussels are cooking. Ensure that shellfish such as mussels and prawns change colour and texture during the cooking process."

"Watch the prawns—see how they're turning from grey to pink? That colour change indicates cooking."

"The mussels are opening and the flesh is changing from translucent to opaque. These are the visual signs I'm looking for."

"Bacteria can survive in shellfish left at ambient temperatures and can also survive when shellfish are undercooked. Full cooking is essential."

Step 5: Common mistakes to avoid

Address the mistakes that lead to shellfish-related food poisoning.

Mistake 1: Accepting deliveries above 5°c. Shellfish must arrive at 5°c or below, covered in ice. Higher temperatures allow bacterial growth. Refuse non-compliant deliveries.

Mistake 2: Storing live shellfish in water. Fresh water kills them; salt water allows dead ones to contaminate live ones. Use the perforated gastronorm ice method—cold without water contact.

Mistake 3: Not checking for dead shellfish. Dead mussels and oysters cause food poisoning. Tap mussels—discard any that don't close. Check oysters are tightly closed. Discard any with milky or bloody juices.

Mistake 4: Opening oysters in advance. Oysters must only be opened on demand. Opening in advance and refrigerating allows bacterial growth and quality deterioration. Open immediately before service.

Mistake 5: Using the wrong tool to open oysters. Only an oyster knife must be used. Other utensils can slip, causing injury, or damage the oyster. Use the proper tool with correct technique.

Mistake 6: Not scrubbing shells before serving. Shells carry dirt, barnacles, and bacteria. Before serving any molluscs, shells must be scrubbed. Remove beards and barnacles from mussels.

Mistake 7: Leaving shellfish at ambient temperature. Bacteria can survive in shellfish left at ambient temperatures. Only remove from refrigeration immediately prior to serving or cooking.

Mistake 8: Keeping too much in service fridges. Service fridges fluctuate during busy periods. Only hold minimal amounts and only place molluscs in the fridge 30 minutes before needed.

Mistake 9: Not retaining health ID tags. Tags must be retained for traceability. Without them, you cannot prove provenance if illness occurs. Keep all paperwork together with delivery documentation.

Mistake 10: Using display fridge shellfish for raw service. Any molluscs kept in glass display fridges can only be used for hot cooked dishes. Display conditions aren't suitable for raw service.

Step 6: Key takeaways

End your video by reinforcing the core principles of shellfish safety.

Approved suppliers only. Shellfish must only be purchased from reputable and approved suppliers with proper HACCP procedures and documentation.

Health ID tags are mandatory. All packages must be delivered with tags. Retain tags and delivery notes for traceability—you must be able to trace any batch if illness occurs.

5°c maximum at delivery. Check temperature upon delivery—refuse anything above 5°c. Products must be covered in ice.

Never store live shellfish in water. Fresh water kills them, salt water spreads contamination from dead ones. Use the perforated gastronorm ice method—cold but dry.

2-day shelf life from delivery. Label with delivery date, discard after two days. Do not freeze live shellfish under any circumstances.

Check every mussel and oyster. Tap mussels—discard any that don't close. Check oysters are tightly closed with clear juices. Discard any with milky or bloody juices, or any that are open.

Discard mussels that don't open after cooking. Closed mussels after cooking were likely dead. Remove from dishes.

Open oysters on demand only. Never open in advance and refrigerate. Scrub shells, check juices, serve immediately after opening.

Scrub all shells before serving. Remove barnacles and beards from mussels. Allocate a dedicated brush for this task.

Minimal quantities in service fridges. Only place molluscs in service fridges 30 minutes before needed. Use ice packs above and below.

Glass display fridge shellfish for cooked dishes only. Display conditions are not suitable for raw service.

Ensure colour and texture changes during cooking. Prawns turn pink, mussels change from translucent to opaque. Undercooked shellfish can harbour surviving bacteria.

Remove from refrigeration only immediately prior to serving. Bacteria multiply at ambient temperatures. Keep shellfish cold until the moment of cooking or service.

Shellfish not stored or handled correctly must be discarded. If staff do not follow these safety points, retrain them and increase supervision until competency can be shown.
