Lamb loin chop
A bone-in chop off the loin. Worth comparing with the lamb steak: same publisher, same 2 cm, and 6–8 minutes a side against 4–6 — the bone and the fat edge are the difference.

Food-safety endpoint
Food Standards Agency
The Food Standards Agency states that whole cuts of red meat such as steaks can be served pink, rare or bloody and will be safe to eat as long as the surface has been adequately seared. It gives no internal temperature for this case, so there is no figure here to cook to — the searing of the surface is the condition.
The rule and its source
In England, Wales and Northern Ireland the Food Standards Agency states that whole cuts of red meat such as steaks may be served pink, rare or bloody, on the condition that the surface has been adequately seared. No internal temperature is given for this case.
Well established
Food Standards Agency — States this directly
“red meat such as steaks can be served pink, rare or bloody and will be safe to eat as long as the surface has been adequately seared”
- What it covers:
- The document states its own reach: 'Applies to England, Northern Ireland and Wales'. Food Standards Scotland publishes separately and, as recorded separately, does not make this statement.
- The permission is CONDITIONAL and the condition is the whole rule: the surface must have been adequately seared, because on a whole cut the contamination is on the surface. A reading that drops the condition has changed the guidance into something else.
- Shape:
- No figure is given, and none is implied. This is a statement about a FORM rather than a temperature, which is why BBQHQ had to be able to record a rule about form at all before this could be held without inventing a number to hang it on.

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, beef, veal and lamb pieces and whole cuts are given a safety figure for each doneness level: 63 °C (145 °F) medium-rare, 71 °C (160 °F) medium and 77 °C (170 °F) well done. Mechanically tenderized beef and veal should reach 63 °C and be turned at least twice during cooking.
- 63 °C (145 °F) — measured at the centre of the thickest part.
- 71 °C (160 °F) — measured at the centre of the thickest part.
- 77 °C (171 °F) — measured at the centre of the thickest part.
The rule and its source
In Canada, beef, veal and lamb pieces and whole cuts are given three safety figures by doneness: 63 °C medium-rare, 71 °C medium and 77 °C well done. Mechanically tenderized beef and veal are given 63 °C and must be turned at least twice during cooking.
Well established
Health Canada — States this directly
“Pieces and whole cuts, for example, steaks and roasts medium-rare 63 145 medium 71 160 well done 77 170”
- Shape:
- A safety chart that speaks in doneness, which is unusual and useful. Most authorities give one safety figure and leave doneness to the cook; Canada publishes the ladder, so a Canadian reader choosing medium-rare is choosing inside official guidance rather than against it.
- The mechanically tenderized row carries a handling instruction rather than only a temperature, which matches BBQHQ's existing claim that tenderised meat behaves like mince.

Tenderised meat is grouped with minced meat rather than with whole cuts, and must be cooked through when barbecued.
Well supported
New Zealand Food Safety / Ministry for Primary Industries — States this directly
New Zealand Food Safety advises that chicken, tenderised meat and minced meat products need to be barbecued until they are cooked through, over 75 °C all the way through.
- Form:
- Groups tenderised meat with mince rather than with whole cuts — direct support for treating mechanical tenderisation as an interior-contamination form.
- Stated specifically in the context of barbecuing.

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.

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.

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.

Culinary doneness — a preference, not a safety figure
medium — 60 °C (140 °F)
Measure at: The centre of the chop, away from the bone.
Beef + Lamb New Zealand publishes the ladder AHDB does not: 50 °C very rare, 55 medium rare, 60 medium and pink, 65 medium well, 72 well done. These are CULINARY preferences from a levy board restricted from the safety domain, and they sit below the safety guidance for New Zealand and for the UK — a reader choosing medium rare lamb is choosing a different level of risk, and BBQHQ states both rather than choosing for them. AHDB gives the times per doneness and no temperatures, so the two publishers together answer a question neither answers alone.
Texture endpoint — how you actually know
Browned on the fat edge, pink and juicy at the centre
The fat along the edge has rendered and coloured rather than sitting white and soft — worth standing the chops on that edge for a minute, because a chop cooked only on its flat faces arrives with raw fat on it.
How long it takes
Lamb chop, direct heat
Estimated cooking window
12 min–16 min
Moderate confidence
Why this is a range, not a number
- Cookers hold temperature imperfectly
- Thickness varies between pieces
- Individual animals and pieces differ
Cook to the endpoint, not to the clock. The window tells you when to start checking.
What this rests on
BBQHQ publishes a window for this cook.

Agriculture and Horticulture Development Board
Also on this page, supplying endpoints or doneness rather than timings: Beef + Lamb New Zealand · 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.
- At least one source does not state the cooker temperature.
- No source states whether the food went on fridge-cold or rested.
How the sources were combined
6–8 minutes a side at 2 cm, so 12–16 in total. One publisher. The interesting comparison is with the lamb STEAK profile: same publisher, same thickness, and half as long again for a chop — the bone and the fat edge are the difference, and having one publisher state both figures is better evidence for that than two publishers each stating one. CLEMSON WAS ADDED HERE AS A SECOND PUBLISHER AND LATER TAKEN BACK OUT. Clemson times a 1 to 1½ inch chop and this profile is for a 2 cm one; the row was inflating both the window and the publisher count of an envelope it does not describe. It moves to the thick-chop profile. This profile is honestly single-publisher, and an earlier correction to the publisher count was wrong for this reason.
What makes the window as wide as it is
- Cookers hold temperature imperfectly
- Thickness varies between pieces
- Individual animals and pieces differ
Thick lamb chops and cutlets, direct heat
Estimated cooking window
7 min–19 min
Low confidence
Why this is a range, not a number

Why confidence is not higher
- Only one source applies to these conditions.
- At least one source does not state the cooker temperature.
- No source states whether the food went on fridge-cold or rested.
How the sources were combined
Clemson supplies the only duration BBQHQ holds for a lamb chop over direct heat — 7-11 minutes at 1 to 1½ inches, with 145 °F stated as medium rare. Beef + Lamb New Zealand supplies no times at all and instead publishes the DONENESS LADDER Clemson gives one rung of: 50 °C very rare through to medium well. The two combine without conflicting because they answer different questions, and that is the only reason this profile can state both a window and a ladder. Two independent publishers, one duration between them.
What makes the window as wide as it is
- Thickness varies between pieces
- How cold the food was when it went on

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