Supreme pizza, from the eater’s side of the box
Six slices, each one a question about the pizza you eat rather than the pizza someone sells: what to do with leftovers, how to ask about allergens, what the kilojoules on a menu board mean, what happens when a delivery goes wrong, what to do about food poisoning, and the smoke from a wood-fired oven next door.
Supreme Pizza is published by Dotto from the official sources linked on each page. It is general information, not medical or legal advice.
Six guides, one pizza
Each guide answers its question in its first two sentences, then goes into the detail, with the official source for each fact listed at the foot of the page.
- Slice 1 · Leftovers
Leftover pizza, the clock and the reheat
How long a slice can sit out, how long it keeps, and reheating it properly.
- Slice 2 · Allergens
Allergens, menus and how to ask
The allergens the law names, what a shop must tell you, and how to ask.
- Slice 3 · Kilojoules
Kilojoules on the menu board
Which chains must show kilojoules, and what the 8,700 kJ line means.
- Slice 4 · Delivery
When a delivery order goes wrong
Fees and surcharges, food kept hot or cold, and refunds for unsafe food.
- Slice 5 · Food poisoning
Food poisoning, and who to tell
The signs, when to see a doctor, and who takes a report in each state.
- Slice 6 · Wood smoke
Wood-fired ovens and the neighbours
Backyard ovens, fire ban days, and smoke that drifts over the fence.
Six figures printed on the side of the box

Who wrote it, and from what
Supreme Pizza is a guide to the eater’s side of pizza, published by Dotto. It is written in plain words from official sources: Food Standards Australia New Zealand, the NSW Food Authority, the ACCC, state and territory health departments, environment protection authorities and fire services. Each page lists its sources at its foot, and every page was checked against them on 8 October 2026.
Rules on food, prices and fires change, and several differ between states. Where a page describes one state’s rule, it says which state. For your own situation, the regulator or council named on each page is the place to ask.
