Pork belly slices

Belly cut into thin strips and grilled fast over direct heat. Layered fat and muscle, which is the whole reason it works and the whole reason it flares.

What it is

Form: Whole muscle
Typical weight: 150–300 g
Typical thickness: 8–15 mm
Cut: Pork belly

Why it behaves as it does

Pork belly is alternating bands of fat and muscle, so a thin slice renders and crisps in minutes while a thick one takes an hour of indirect heat to become tender — two completely different cooks from one cut, decided entirely by how it was sliced. Sliced thin it is among the fattiest things on a barbecue, which makes it one of the most reliable causes of flare-up in the catalogue. It arrives here because the Korea Tourism Organization names grilled pork belly as the most popular Korean meat dish, and a tradition BBQHQ documents was unintelligible without the food at the centre of it.

When is it done?

Food-safety endpoint

Food Standards Agency
The Food Standards Agency names pork alongside chicken and minced products as food that should not be served pink or rare, because bacteria can be present within the meat rather than only on its surface. A whole cut of pork is therefore not covered by the permission the same guidance gives to steaks.
The rule and its source
The same Food Standards Agency guidance names pork and chicken, with minced products, as foods that should not be served pink or rare — placing whole cuts of pork on the opposite side of the sentence from whole cuts of beef and lamb.
Well established
- Food Standards Agency — States this directly
  “other meats, like chicken and pork, as well as minced meat products such as burgers, kebabs and sausages should not be served pink or rare as bacteria can be in the meat”
  What it covers:
  Applies to England, Northern Ireland and Wales, as the document states.
  Pork is named, as a species, on the restricted side. This is the sentence that stops the red-meat permission being read as covering whole cuts generally: a pork loin is a whole cut and is excluded by name.
  Shape:
  Again no figure. The FSA's numerical endpoint — 70 °C for two minutes or an equivalent — is published in its business guidance and modelled separately; this sentence is a form rule and is recorded as one.

USDA Food Safety and Inspection Service
In the United States, whole cuts of beef, pork, lamb and veal — steaks, chops and roasts — should reach 145 °F (63 °C), followed by a rest of at least three minutes before carving or eating.
- 63 °C (145 °F) — measured at the centre of the thickest part, away from bone and fat.
The rule and its source
In the United States, whole cuts of beef, pork, lamb and veal have a safe minimum internal temperature of 145 °F (63 °C), followed by a rest of at least three minutes.
Well established
- United States Department of Agriculture, Food Safety and Inspection Service — States this directly
  “Cook raw beef, pork, lamb and veal steaks, chops, and roasts to a minimum internal temperature of 145 °F ... allow meat to rest for at least three minutes”
  Form:
  Whole cuts only. Ground meats are covered by a separate, higher figure.
  The three-minute rest is part of the safety requirement, not only a quality step.
  How it was measured:
  As measured with a food thermometer before removing from the heat source.

Health Canada
In Canada, pork pieces and whole cuts — bone-in chops, boneless loin chops, rib roast and loin roast — should reach 71 °C (160 °F), and fish 70 °C (158 °F). Shellfish and crustaceans are 74 °C. No rest interval is attached to any of these.
- 71 °C (160 °F) — measured at the centre of the thickest part.
- 70 °C (158 °F) — measured at the thickest part of the fillet.
The rule and its source
In Canada, pork pieces and whole cuts should reach 71 °C (160 °F), and fish 70 °C (158 °F). No rest interval is attached to either.
Well established
- Health Canada — States this directly
  “Pieces and whole cuts, for example, bone-in chops, boneless loin chops, rib roast, loin roast 71 160 ... Fish 70 158”
  The sharpest disagreement in the catalogue between two neighbours. Canada gives a pork chop 71 °C; USDA FSIS gives 63 °C with a three-minute rest. That is eight degrees and a rest interval between two countries whose supermarkets sell the same cuts. Fish diverges too: 70 °C against the American 63 °C.
  Canada's chart attaches no rest interval to any row.

Food Standards Australia New Zealand
Use separate equipment for raw and cooked meat, and never put cooked meat back on a tray or plate that held it raw. Throw away leftovers unless there is refrigeration available to cool them quickly.
The rule and its source
At a barbecue, raw and cooked meat must be kept apart: separate equipment, and cooked meat never returned to the tray that held it raw.
Well established
- Food Standards Australia New Zealand — States this directly
  “never place cooked meat back on the trays that held the raw meat”
  The single most common barbecue food-safety failure, and one that no cooking temperature prevents.
  Where it applies:
  Australia and New Zealand.

Food Standards Agency
Wash a thermometer stem in hot soapy water before and after each use, and do not put the head in water.
The rule and its source
A thermometer stem should be washed in hot soapy water before and after each use, and the head should not be put in water.
Well established
- Clemson Cooperative Extension — States this directly
  “Make sure to clean the stem of your food thermometer with hot soapy water before and after each use. Do not immerse the head in water.”
  Before and after, not just after. a probe that went into an undercooked bird and then into the next one is a cross-contamination route BBQHQ's food-safety model already recognises between surfaces and hands, and has never described for the instrument that touches every piece of meat on the grate.
  The head exclusion is an equipment instruction rather than a hygiene one — electronics — and is recorded here because it is in the same sentence and separating them would misquote the source.

When it goes wrong

It caused flare-ups: Flare-ups — 2 distinguishable causes.

Afterwards

Cooling, keeping and reheating what is left is general guidance for barbecue leftovers. Neither UK authority publishes anything specific to pork belly slices, and BBQHQ does not invent a distinction they do not make.
