Hong KongSewage and waste: the rules, and the one that closes a kitchen
Waste is stored in durable, cleanable, leak-proof receptacles, covered outside, and removed often enough to prevent odor and pests. A sewage backup into the establishment is an imminent health hazard requiring closure and notification.
Three of the fifteen contamination questions are about waste disposal, which puts it level with bare-hand contact. It is not a footnote area.
Inside
- Receptacles that are durable, cleanable, insect and rodent resistant, leak-proof and non-absorbent.
- Emptied often enough that they do not overflow or attract anything.
- Kept covered where they hold food waste and are not in continuous use.
- Cleaned regularly, inside and out, in an area where the wash water does not contaminate anything.
- Handwashing after handling waste, every time.
That last point is where waste handling connects to the rest of the exam. The bin is not the hazard; the hands that touched it and then touched food are.
Outside
Containers with tight-fitting lids, kept closed. On a smooth, non-absorbent, sloped surface that can be cleaned and drained.
The area matters as much as the container. Standing water, spilled waste and cardboard stacked against a wall are what turn a bin area into a pest habitat, and pest questions and waste questions overlap heavily.
A back door held open because staff are carrying rubbish out is the single most common route for flies and rodents into a kitchen. It appears as a scenario in both waste and pest questions, and the answer is the same: the door closes.
Sewage
Disposed of through an approved system. Where the establishment is not on a public sewer, a private system approved and maintained.
And then the rule that closes a kitchen: a sewage backup into the establishment is an imminent health hazard. Cease operations, notify the regulatory authority, reopen with their approval.
Not clean it up and carry on. Not close that section. Cease operations. It sits alongside fire, flood, extended power loss and a suspected outbreak in the same provision, and the response is identical for all of them.
Grease and liquid waste
Grease goes to an interceptor sized for the load and cleaned on a schedule with records kept. Liquid waste goes down the service sink, never into a storm drain and never out the back door.
Recycling and returnables
The same rules apply. Containers for returnable bottles and cans attract pests exactly as effectively as a rubbish bin, and are stored the same way.
It is a small point and it is the kind of detail that turns into a question, because it tests whether you learned the principle or just the word "garbage".
Common questions
What are the requirements for waste receptacles?
Durable, cleanable, insect and rodent resistant, leak-proof and non-absorbent. Covered outside and when holding food waste indoors, emptied before they overflow, and cleaned regularly inside and out.
What happens if sewage backs up into the establishment?
It is an imminent health hazard. Cease operations and notify the regulatory authority immediately; reopening requires their approval. Cleaning up and continuing is not an option.
Where should the outside bin area be?
On a smooth, non-absorbent, sloped surface that can be cleaned and drained, with tight-fitting lids kept closed. Standing water and stacked cardboard around bins create pest habitat.
Do you have to wash your hands after taking out rubbish?
Yes, every time. The waste itself is not the hazard - the hands that handled it and then touch food are, which is why this appears under both waste and hygiene.
Do recycling containers follow the same rules?
Yes. Returnable bottles and cans attract pests just as effectively as food waste, so the same storage, covering and cleaning requirements apply.
