Pork shoulder

A cut that passes its safety endpoint hours before it is ready, which makes it the clearest demonstration that safety and texture are different questions.

What it is

Form: Bone-in joint
Typical weight: 2.0–4.0 kg
Typical thickness: 100–160 mm
Cut: Pork shoulder

Why it behaves as it does

Collagen conversion is a function of time as well as temperature, so a shoulder held lower for longer can finish better than one pushed hard to the same number. The National Pork Board's signal is the one to use: the bone slips out cleanly, at around 85–88 °C.

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.

Texture endpoint — how you actually know

Probe tender — the joint pulls apart under light pressure and the bone slips free

A probe or skewer slides into the thickest part with almost no resistance, and the blade bone can be pulled clean out by hand. The National Pork Board gives the same signal and puts it at around 85–88 °C. This happens long after the meat is safe to eat, and no thermometer reading substitutes for the feel.

Indicative only: 85–96 °C (185–205 °F). This is not a target to cook to — the feel decides.

Where this comes from

Smoked pork shoulder is taken to roughly 85–88 °C, far above any safety endpoint, and the National Pork Board's stated signal is that the bone slips easily from the meat.

Limited evidence — treat with caution

National Pork Board — States this directly
The National Pork Board gives a target internal temperature of 185 to 190 °F for smoked pork shoulder, at which point it states the bone will slip easily from the meat, and expresses the time as a rate of about one hour and fifteen minutes per pound.
Endpoint:
185–190 °F, about 85–88 °C. Far above the 145 °F safety figure on the same publisher's grilling chart.
Form:
The duration is a RATE per pound, not a total, so it cannot be recorded as a duration without choosing a weight.
The bone slipping free is a physical signal, not a temperature.

How long it takes

Pork shoulder, low and slow

Estimated cooking window

Research needed. The one duration source retrieved gives a rate of about 1 hour 15 minutes per pound rather than a window. Long cooks vary by many hours between joints of the same weight, and a figure here without strong evidence would be actively misleading. See the open question.

What this rests on

BBQHQ publishes no window — the evidence is not there yet.

Observations: 2
Documents: 2
Publishers timing this cook: 0

Also on this page, supplying endpoints or doneness rather than timings: National Pork Board · United States Department of Agriculture, Food Safety and Inspection Service. They are not a second opinion about how long the cook takes.

Why confidence is not higher

Only one source applies to these conditions.
The endpoint is well established; the timing behind it is not. Cook to the endpoint.
At least one source does not state the cooker temperature.
No source states the weight of the food.

How the sources were combined

The safety endpoint is inherited from the whole-cut observation and is passed several hours before the joint is ready — which is the entire point of this record. The National Pork Board's texture endpoint of 185–190 °F with the bone slipping free is a genuine improvement on the unsourced description it replaced. Its DURATION is still not published, because the Pork Board expresses it as a rate per pound rather than a window, and turning that into hours means choosing a weight — arithmetic that would be BBQHQ's and would arrive on the page looking like the source's.

What makes the window as wide as it is

Weight varies within the range this covers
Cookers hold temperature imperfectly
Individual animals and pieces differ

Afterwards

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

Traditions that cook it

Memphis barbecue
A Tennessee barbecue practice centred on smoked pork shoulder, distinct from the whole-hog cooking of the west Tennessee region around it and from the sauced hams and shoulders of the east.
