The leaking bag and the mislabelled 白子
A licensed handler works alone from 14:00 to 16:00 to break down eight トラフグ for an evening party. His apprentice, who holds no licence, removes the 肝臓 and 卵巣 with the same 出刃包丁 and on the same まな板 used minutes earlier for the 身欠き that will be served as sashimi. The livers go into a thin polyethylene bag that is dropped into the general food-waste bin by the back door; the bag leaks a trail across the floor to the walk-in. One fish has a small, pale 卵巣 that the apprentice mistakes for 白子 and adds to the 白子 container. Eyes and gills are pushed into the sink strainer. At 17:00 a party of 20 orders 白子焼き and ふぐ刺し, and the sashimi is plated on the same board, wiped with a cloth.
1. Identify the two most serious failures here and state the immediate action for each.

First, the unlicensed apprentice performed the licensed act. That is not a paperwork point: the licence is the control that prevents precisely the next error. Second, the 卵巣 went into the 白子 container. トラフグ ovary is highly toxic, and once separated a small pale ovary cannot be reliably distinguished from 白子 by eye - so there is no inspection that rescues the container. The whole 白子 container must be discarded as toxic waste, the 白子焼き for 20 guests cancelled or replaced from verified stock, and the incident recorded.
Both failures are reportable-quality problems even if nobody is harmed; at minimum they belong in the diary and in retraining, and the licence holder must decide whether the 保健所 should be informed.
Until the container is out of the kitchen and the board and knife are dealt with, no fugu dish leaves the pass.
2. The knife, board and cloth, the floor trail, and the sink strainer with eyes and gills: set out the cleaning sequence and the tool policy.

Tetrodotoxin is not alive and not volatile; it is removed by physical cleaning plus disinfection, or not at all. A wipe with a cloth across a contaminated board spreads it and then deposits it on the next fish - that is the single most dangerous step described.
Sequence: put on fresh gloves; take the board and knife out of the fugu line; wash with detergent and warm water to remove visible residue; rinse; then heat-treat (80 °C or above, or boiling water) or use 200 ppm chlorine, and air dry. Retire the board from ready-to-eat use; a dedicated, colour-coded fugu board and knife is the durable fix, and the knife used on liver must never touch sashimi.
The floor: absorb the trail with paper, bag it as toxic waste, wash with detergent, disinfect, and treat the shoes that crossed it as contaminated. The sink strainer with eyes and gills must be emptied into the toxic-waste container and the sink cleaned and disinfected before any food or utensil touches it.
3. How should the livers, ovaries, eyes and gills have been handled from removal to final disposal?
Read the worked answer
From the moment they are cut out, toxic organs should go into a rigid, closable, clearly labelled container kept in a designated place away from food - ideally lockable, and cold if they will be held. A thin bag in the general bin by the back door fails on every count: it is unlabelled, reachable by staff and animals, unrecorded, and it leaks.
The record should capture date, species, number of fish, organs removed, approximate quantity, the name of the licence holder, and the disposal route and date. Disposal follows the prefectural rule - normally consignment to a licensed waste contractor with a manifest, not the municipal food-waste stream.
At the end of the session someone checks the container is closed, labelled and stored, and that count of organs matches count of fish. The leak to the walk-in is a reminder that the container, not the bin, is the control point.
