Seafood stall QC - the iced-seafood sensory receiving checklist: five-point fish inspection, shrimp necks, shellfish tap tests - each failed item gets its prescribed disposition

Write a sensory receiving checklist for iced seafood arrivals, used
at the wholesale market before dawn or at the stall, sixty seconds
per lot. Four blocks - fish, shrimp, shellfish, cephalopods; each
line three fields: where to look / pass line / disposition on
failure (reject the lot | cull part | accept marked down).

1. Fish (whole iced; all five points together - never one or two)
- Eyes: clear and slightly bulging passes; cloudy and sunken
  marked down
- Gills: lift the plate - bright red passes; dull or grayish
  marked down; blackened with off-odor rejects the lot
- Scales: tight and glossy passes; large-scale loss (excess
  transit abrasion) marked down
- Flesh: press the back, quick bounce passes; dent that stays
  rejects
- Belly: firm with the vent flush passes; swollen belly with
  protruding vent rejects - internal spoilage cannot be groomed
  from outside, which makes this point the mirror no made-up
  fish escapes
- Why five together, printed at the card's foot: ice-grooming
  can freshen eyes and gill color; checking them alone gets you
  fooled

2. Shrimp
- Head-shell joint: tight passes; loose or blackening marked
  down. Blackening starts at the head as a rule - distinguish
  degrees: head-dark alone = degree issue, markdown; head-dark
  PLUS slimy flesh PLUS off-odor = spoilage, reject
- Shell color: species' natural color passes; reddening judged
  per species (some shrimp redden naturally - when unsure,
  markdown, don't reject on the spot)
- Odor: seawater smell passes; ammonia rejects

3. Shellfish
- Closing strength: snaps shut when tapped, or resists a gentle
  pry, passes; gaping and hollow-sounding are dead - dead past
  the tolerance share rejects the lot, scattered ones culled
- Note: shellfish inspect for dead-or-alive, not freshness -
  a dead shellfish is worth zero; there is no "markdown" tier
- Shell damage: scattered culled; proportional rejects

4. Cephalopods (squid, octopus)
- Skin brightness and flesh texture: bright and firm passes;
  slimy rejects
- Odor: seawater passes; ammonia rejects

General moves (card top):
- Check net-weight matters first (bag water, ice packing,
  glaze) - weight gaps belong to the receiving audit process;
  this card judges quality only; keep the two verdicts separate
- Sample from the bottom of the lot: spoiled goods hide at the
  bottom as a rule; checking the surface only inspects nothing
- Large lots that won't clear in sixty seconds get marked down
  - drag the inspection and the market's trucks won't wait, and
  neither will your opening

Card foot: your grounds for rejection are this card - reject by
the card, no debating with the supplier; when unsure, take it
marked down, never a hard rejection.

Format: four blocks, one A5 card double-sided, row spacing wide
enough for hand-ticking.

Why it is written this way

Sensory inspection is the QC's last line of defense and the only one that can't be outsourced: the lab report describes the goods at the plant, the gill color at arrival describes them now - and between the two lies a stretch of transport nobody sees. The card blocks out four categories rather than one generic table because the judgment axes differ completely: fish take five points together, shrimp turn on the head-shell joint and "how black is black," shellfish test dead-or-alive, cephalopods read slime - one blended table guarantees missed items.

The fish "five points together" defeats made-up goods: ice grooming keeps eyes clear and gills bright, but flesh bounce and belly condition can't be faked - a swollen belly with a protruding vent is internal spoilage projected outward, the least groomable of the five points. An inspector checking one or two points gets fooled by surface state; five together raise the cost of fakery past what fakery can pay.

"'When unsure, take it marked down, not rejected' is the QC's decision stop-loss. A pre-dawn market rejection carries confrontation cost - the supplier argues, the clock burns, three more lots wait behind it. Treat "unsure" as "reject" and you burn supplier goodwill; treat it as "pass" and you burn customers. Markdown acceptance is the middle channel that burns neither: the goods still come in (the relationship holds) but with changed status (markdown section, posted, never the full-price counter).

"The net-weight line belongs to the audit, quality to this card" must be stated too: when one bag of shrimp is both short-weighted and blackening, the two failures travel different channels - the shortage goes back at the supplier, the spoilage disposes per the card. Judge them together and the supplier's "here, two extra shrimp" papers over the spoiled lot as well.
