Fishmongers: where each piece comes from

The counter mixes what the box kept apart. What you must be able to say about each piece is decided on receipt, not at the sale.

Updated on 13/08/2026

Fish arrives in boxes, each with its label and its data. On the counter it is laid out by species and size, which is how customers ask for it. Between those two things there is a jump: the box knew where each piece came from and the counter no longer does, unless someone wrote it down along the way.

What you must be able to say about each piece

DetailWhere it comes from
Which species, with its scientific nameThe box label
Where it was caught or farmedThe same, and not always the supplier's location
Whether it is wild-caught or farmedThe same
Whether it has been frozenThe delivery note and your own handling

Important

**Traceability is not lost at the counter: it is lost when the boxes are emptied.** While the box is intact, everything is on its label. The moment the goods move to a tray, the information exists only if someone copied it somewhere. So the recording happens on receipt, with the box in front of you, not at the end of the day trying to reconstruct what was in each tray.

Two things that complicate the counter

Watch out

A confusion that costs money with suppliers: **the commercial name and the species are not the same thing, and several different species are sold under one popular name**. If the box arrives with the commercial name and nothing else, the detail you will be asked for is missing. It is not bureaucratic detail: it is what lets you respond when an alert affects one specific species and not the one you thought you were selling.

Worth knowing

What information must accompany each fishery product, how it must be presented to the consumer and which records must be kept is set by the applicable rules, and varies for fresh, frozen, processed or retail sale. **Your adviser or health authority settles that**; here we explain where it breaks in practice.

Do I have to keep the box labels?

Keep at least their information. It is the source of everything else.

What if I mix two deliveries of the same species?

Then the piece belongs to both, and an alert affects all of it.

Can defrosted fish be sold?

Yes, but identified as such. It is among the most closely watched points.

A real case

The situation

Boxes are emptied in the morning and by mid-afternoon nobody knows which delivery is in which tray.

What you do

  1. Records the label information on receipt, with the box in front of them

What you get

Every tray can say where it came from with nothing reconstructed.

The situation

An alert arrives affecting one species and the delivery note carries only the commercial name.

What you do

  1. Requires the scientific name from the supplier on every delivery

What you get

Whether you are affected is known in minutes rather than after asking and waiting.

The situation

Two different deliveries of the same fish get mixed in one tray.

What you do

  1. Keeps deliveries apart while possible and records it when they merge

What you get

An incident is contained to one delivery instead of the whole counter.

The situation

A box arrives and its origin is not recorded.

What you do

  1. Records the origin on receipt

What you get

The fact exists when somebody asks.

The situation

The counter mixes pieces from two intakes.

What you do

  1. Records which intake supplied each display

What you get

You can say where each piece came from.

The situation

A customer asks about what they bought yesterday.

What you do

  1. Checks what was recorded that day

What you get

You answer from the record.
