The Complete Safe Chain
Use the same chain in every session.
RECEIVE INSPECT SORT HANDLE PRESERVE CLEAN STORE RECORD
• Receive: bring the catch into a safe, clean handling area.
• Inspect: check freshness, hazards, equipment, and contamination risk.
• Sort: separate by form, condition, and intended use.
• Handle: use clean tools, PPE, and gentle transfer.
• Preserve: choose a safe method if fish will not be used immediately.
• Clean: remove wastes and sanitize surfaces and tools.
• Store: protect from pests, heat, dirt, and unsafe containers.
• Record: write what was done, concerns, and corrections.
Safety question: What could go wrong at this step, and how will we control it?

5
Vocabulary for the Week
• Precaution: an action done to prevent danger or harm.
• Fresh fish: fish that has not been preserved or treated other than chilling
and still shows good quality indicators.
• Stale fish: fish showing deterioration, unpleasant odor, poor appearance,
or unsafe quality signs.
• Spoilage: the process in which food stops being good enough or safe to
use.
• Fish cut: the shape or portion produced from cutting fish.
• Market form: the way fish is prepared or offered for sale or cooking.
VISUAL GUIDE
Word wall: precaution, safety,
fresh, stale, spoilage, tools,
equipment.

Non-Negotiable Safety Rules
• Learners use pictures, cards, paper fish, clay, soft models, or teacher-controlled
demonstrations only.
• No learner uses sharp knives, live heat, smoke, boiling water, chemicals, unsafe
containers, or questionable fish.
• Do not taste, closely smell, or handle fish with uncertain quality.
• Any strong off-odor, slime, contamination, broken glass, unsafe heat, damaged
equipment, or missing PPE means stop and report.
• Assessment focuses on safe reasoning and correct sequence, not speed or real
food processing.

SESSION 1
Fish Cuts and Market Forms
How does post-harvest preparation affect safety, use, and quality?
VISUAL GUIDE
Safe classroom learning uses
pictures, cards, paper/model
fish, and teacher-approved
demonstration only.

8
From Harvest to Market Form
• Week 8 sequence ended with handling, cleaning, storing, and recording
the catch.
• Week 9 asks what happens next: fish may be kept whole, cleaned, cut,
inspected, cooled, cured, or prepared for later use.
• Each change requires sanitation, correct tools, and safety precautions.
• A cut changes the portion or shape of fish. A market form describes how
the fish is offered for cooking or sale.
VISUAL GUIDE

forms.

9
Fish Cuts: Shape and Portion
Cuts describe how the fish portion is shaped.
Darne
thick cross-cut of round fish, often for steak
Supreme
boneless portion from fillet or loin
Fillet
side of fish separated from backbone
Paupiette
thin fillet rolled and often stuffed
Delice
small folded fillet, often from flat fish
Goujon / Goujonette
small strips; goujonette is smaller finger-food size
Safety cue: learners identify cuts from pictures or harmless models. Actual cutting requires trained-adult demonstration and approved
procedures.

10
Market Forms of Fish
Market forms describe how fish is offered or prepared.
Whole / Round
sold as caught; must be scaled and
gutted before cooking
Drawn
internal organs removed
Dressed
ready to cook; usually head, tail, and
fins removed
Fillets
sides cut away from backbone; often
boneless
Steaks
ready-to-cook cross-sectional slices of
large fish
Remember: “fillet” can be both a cut and a market form depending on how it is being described.

11
Cut or Market Form?
Use the distinction before classifying.
Fish Cut
describes the shape, portion, or cutting style
produced from a fish. Examples: darne,
supreme, paupiette, delice, goujon, goujonette.
Market Form
describes how the fish is offered, prepared, or
sold for cooking. Examples: whole, drawn,
dressed, fillets, steaks.
Check yourself: Am I naming the shape of the portion, or the way it is offered for use?

12
Safe Master Cutter Adaptation
• The Lesson Exemplar includes a Master Cutter task. In this deck, the
learner-safe version uses paper, clay, banana, or teacher-prepared models.
• A trained adult may demonstrate with a safe substitute under controlled
conditions, but learners do not use sharp knives.
• Each group labels the cut or market form, intended use, normally required
tool, hazard, and safety control.
• Learning target: recognize forms and explain why preparation affects
edible portion, handling, and intended use.

offered or prepared for use.
• Every preparation step requires cleanliness, correct tools, and hazard
control.
• Learners can demonstrate understanding with pictures, paper models,
labels, and safety explanations.
VISUAL GUIDE
Exit ticket: The difference
between a fish cut and a
market form is ___.

SESSION 2
Freshness and Spoilage Decisions
How can we judge fish quality using evidence and protect consumer
health?
VISUAL GUIDE
demonstration only.

17
Freshness Detective: Use Several Indicators
• Never rely on only one sign. Use at least two or more indicators before
making a decision.
• The main indicators are odor, eyes, gills, flesh, and overall physical
appearance.
• Use pictures, diagrams, and teacher-approved sealed samples only. Do
not taste questionable fish or smell closely.
• Decision choices: Accept, Chill/Handle Immediately, or Reject-and-Report.
VISUAL GUIDE
Evidence board with odor,
eyes, gills, flesh, and
appearance cards.

18
Fresh Fish Indicators
Freshness evidence should be clean and consistent.
• fresh and not unpleasant odor
• full, bright eyes with black pupil and transparent cornea
• brightly colored, clean gills without offensive odor
• firm and elastic flesh that adheres to bone
• clean, bright, smooth, moist appearance without discoloration
VISUAL GUIDE
Fresh-fish photo/card set:
bright eyes, clean gills, firm
flesh, clean moist surface.
Fresh does not mean “safe forever.” Even fresh fish must be kept clean, cool, protected, and recorded.

19
Stale Fish Indicators
Unsafe signs require adult reporting.
• sour, decomposing, or putrid odor
• sunken or shrunken eyes, yellowish slime, milky pupil
• discolored, slimy, dirty gills
• soft, limp flesh that pits under pressure or tears easily
• lifeless, dry, rough, bleached, or discolored appearance
VISUAL GUIDE
Reject-and-report card: strong
off-odor, slime, discoloration,
unsafe storage history.
Learner rule: Do not taste, closely smell, sell, or mix questionable fish with fresh fish. Stop and report to a responsible adult.

20
Agents and Factors of Spoilage
Spoilage is caused by living and chemical processes.
Agents of Spoilage
• microorganisms such as bacteria and other
microscopic organisms
• enzymes naturally present in fish tissues and
digestive tract
Factors that Hasten Spoilage
• high moisture, protein, or fat content
• bacterial contamination
• warm temperature or delayed chilling
• unhygienic handling
• weak muscle tissue and poor handling after
harvest
Cause-and-effect: warm temperature + contamination + delayed handling = faster spoilage risk.

21
Freshness Decision Routine
Use evidence before acting.
LOOK COMPARE CITE 2 SIGNS DECIDE REPORT / RECORD
1. Look at the picture, sample card, or teacher-approved demonstration.
2. Compare evidence using odor, eyes, gills, flesh, and appearance.
3. Cite at least two signs.
4. Choose Accept, Chill/Handle Immediately, or Reject-and-Report.
5. Record your reason so the decision is honest and traceable.
Good answer frame: I choose ___ because I observed ___ and ___. The safe action is ___.

22
Freshness Evidence Board
• For four picture-based cases, identify the condition of the fish.
• Cite at least two evidence indicators for each case.
• Name one possible spoilage factor or hazard.
• Choose Accept, Chill/Handle Immediately, or Reject-and-Report.
• Ask for teacher verification when the evidence is unclear.
VISUAL GUIDE
Board with four fish cases and
three decision cards.

23
1. Which indicates fresher fish? A. Bright full eyes B. Milky sunken eyes C. Putrid odor D. Limp flesh
2. Which gills are more consistent with fresh fish? A. bright, clean, no offensive odor B. dark brown
and slimy C. dry and dirty D. covered with yellow slime
3. Which is an agent of spoilage listed in the lesson? A. Microorganisms B. Clean ice C. Hairnet D.
Food tray
4. Which condition can hasten spoilage? A. unhygienic handling and warm temperature B. prompt
chilling and clean containers C. accurate records D. covered storage
5. What should a learner do with fish that has a strong decomposing odor? A. taste it B. reject and
report to an adult C. mix with fresh fish D. wash and sell immediately
1-A, 2-A, 3-A, 4-A, 5-B.
Reteach: require two
indicators before deciding.

24
• Freshness judgment uses evidence from several indicators, not
guesswork.
• Microorganisms, enzymes, heat, contamination, moisture, and poor
handling can hasten spoilage.
• Questionable fish should be rejected and reported, not tasted or
mixed with good fish.
• Consumer health depends on honest inspection, chilling or safe
handling, and records.
VISUAL GUIDE
Exit ticket: One freshness sign
is ___; one spoilage factor is
___; one safe action is ___.

25
SESSION 3
Fish Curing Principles
How do drying, salting, smoking, and pickling slow spoilage?
VISUAL GUIDE
demonstration only.

26
Why Cure Fish?
• Fish curing is a way to slow spoilage and extend usable storage
time.
• Common methods include drying, salting, smoking, pickling, or
combinations of these methods.
• Curing does not make unsafe fish safe. It must begin with
acceptable fish and clean work practices.
• Correct amount, time, containers, temperature, storage, and adult
supervision matter.
VISUAL GUIDE
Four preservation pictures:
dried, salted, smoked, pickled
fish.

27
Four Curing Methods at a Glance
Match each method to its principle.
Drying
removes moisture so microorganisms cannot grow
easily
Salting
uses salt to draw water out of food and reduce
spoilage conditions
Smoking
uses controlled smoke and often heat for flavor,
color, and preservation effects
Pickling
uses brine with salt and acid, often vinegar, to
extend shelf life
Cue: Moisture • Salt • Smoke • Acid

28
Drying and Salting
Two methods reduce available moisture.
Drying
removes moisture. It needs clean drying
surfaces, protection from dust, insects, animals,
rain, and proper storage after drying.
Salting
uses salt to draw water from food. It needs
correct amounts, clean containers, approved
procedures, and good storage.
Misconception check: Salting is not simply heating. It mainly works through salt action and moisture reduction.

29
Smoking and Pickling
These methods require stronger safety controls.
Smoking
exposes food to controlled smoke and often
heat. Hazards include fire, burns, smoke
inhalation, poor ventilation, and unsafe storage.
Learners do not operate a smokehouse.
Pickling
uses brine with salt and acid. Hazards include
hot liquid, broken glass, wrong formulation,
dirty jars, and unsafe storage. Use food-grade
containers and adult supervision.
Safe statement: Real curing is a trained-adult, school-approved food-safety task. Classroom learning may use paper fish and
process cards.

30
Curing Comparison Matrix
Compare before choosing.
Method Principle Equipment Hazard Safety Control Storage
Example: Drying | removes moisture | trays/racks/dehydrator | dust or insects | covered clean drying area | protected dry storage
Learner task: complete one row for drying, salting,
smoking, and pickling. Then choose one method for a
scenario and justify the choice using the matrix.
VISUAL GUIDE
Matrix output + scenario
cards: abundant catch, no
cold storage, dried
product, acidic brine,
controlled smoking.

31
Scenario Decision: Choose a Method
• Abundant fish with no cold storage: choose a method that can slow spoilage
safely, such as drying or salting under approved conditions.
• Fish intended as a dried product: drying is the main method, with protection from
contamination.
• Fish to be kept in acidic brine: pickling is the method, with clean food-grade jars
and correct formulation.
• Fish intended for controlled smoking: smoking requires trained-adult operation,
ventilation, and heat/smoke controls.
• Always justify using hygiene, equipment, hazards, and storage needs.

32
Junior Preservers: Harmless Planning Task
• Groups prepare a step-by-step plan or tabletop simulation using paper
fish and labeled ingredient or equipment cards.
• The plan must include method, principle, equipment, PPE, hygiene, hazard
controls, storage, and stop conditions.
• Actual curing is allowed only as a trained-adult demonstration under
school-approved food-safety procedures.
• Peers check: Is the method matched to its principle? Are hygiene, PPE,
equipment, and storage included?
VISUAL GUIDE
Paper fish + labeled cards:
salt, vinegar, smokehouse,
tray, jar, PPE.

33
1. Which method preserves mainly by removing moisture? A. Drying B. Trapping C. Sorting D.
Filleting
2. Which method uses salt to draw water from food? A. Salting B. Smoking C. Drawing D. Dressing
3. Which method exposes fish to controlled smoke and often heat? A. Smoking B. Pickling C.
Freezing D. Filleting
4. Which method commonly uses brine with salt and acid? A. Pickling B. Drying C. Seining D.
Dredging
5. Which statement is safest? A. learners operate smokehouse alone B. actual curing requires
approved procedures and trained-adult supervision C. questionable fish should be tasted D. any
container may be used
1-A, 2-A, 3-A, 4-A, 5-B.
Reteach: Moisture-Salt-
Smoke-Acid cue.

34
• Fish curing slows spoilage through moisture removal, salt action, smoke
and heat exposure, or acidic brine.
• The method must match the fish condition, intended use, available
equipment, and safety controls.
• Traditional practice does not automatically guarantee safety; hygiene and
approved procedure matter.
• A safe plan names hazards, PPE, stop conditions, storage, and records.
