For a buyer the practical points are the form bought, the basis a result is reported on, where the lamb chop came from and the laboratory’s reporting limit. Testing finds contamination but does not remove it.

What counts as lamb chop

This page covers lamb chop in 4 forms kept separate in every comparison: lamb chop, as sold (119 results), lamb chop, cooked (10 results), lamb chop, oil (8 results) and lamb chop, frozen (4 results).1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →3Marín S, Pardo O, Sánchez A, Sanchis Y, Vélez D, Devesa V, Font G, Yusà V · 2018Assessment of metal levels in foodstuffs from the Region of Valencia (Spain)Toxicology Reports 5 (2018) 654-670Read source →4Adilbekov Z, Mustafina R, Suleimenov S, Serikova A, Zhuzzassarova G, Suranshiyev Z, Bainiyazov A · 2026Technogenic contamination of livestock- and fish-derived food products with heavy metals and radionuclides in industrial and post-nuclear regions of KazakhstanVeterinary World 2026, 19(3): 1052-1068Read source →5Baxter M, Brereton N · 2015Total Diet Study of metals and other elements in foodFood and Environment Research Agency report for the UK Food Standards Agency, Fera report 15/06, project FS102081Read source →6Dabeka RW, McKenzie AD · 1995Survey of Lead, Cadmium, Fluoride, Nickel, and Cobalt in Food Composites and Estimation of Dietary Intakes of These Elements by Canadians in 1986-1988Journal of AOAC InternationalRead source →

Results stay on the basis each source reports: as sold or fresh weight, dry weight, or unstated. Dry-weight, as-sold and unstated results are never pooled, and no moisture conversion is applied.

Heavy metal contamination profile of lamb chop

The table holds every extracted lamb chop result: one row for each statistic a source reports for a form, group and metal, 141 rows in all, grouped by metal and form; percentiles, ranges and maxima for the same samples as a mean or median are shown on that row.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →3Marín S, Pardo O, Sánchez A, Sanchis Y, Vélez D, Devesa V, Font G, Yusà V · 2018Assessment of metal levels in foodstuffs from the Region of Valencia (Spain)Toxicology Reports 5 (2018) 654-670Read source →4Adilbekov Z, Mustafina R, Suleimenov S, Serikova A, Zhuzzassarova G, Suranshiyev Z, Bainiyazov A · 2026Technogenic contamination of livestock- and fish-derived food products with heavy metals and radionuclides in industrial and post-nuclear regions of KazakhstanVeterinary World 2026, 19(3): 1052-1068Read source →5Baxter M, Brereton N · 2015Total Diet Study of metals and other elements in foodFood and Environment Research Agency report for the UK Food Standards Agency, Fera report 15/06, project FS102081Read source →6Dabeka RW, McKenzie AD · 1995Survey of Lead, Cadmium, Fluoride, Nickel, and Cobalt in Food Composites and Estimation of Dietary Intakes of These Elements by Canadians in 1986-1988Journal of AOAC InternationalRead source → Monitoring medians are HMI calculations from individual submissions; non-detects remain intervals between zero and the reporting limit and are never read as zero.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →

Comparison methods and scope

Each row is one statistic a source reports for one form of lamb chop, group and metal; percentiles, ranges and maxima reported for the same samples as a mean or median are shown on that row. Different forms and preparation states are kept apart, and dry-weight results never share a reference with as-sold or fresh-weight results. Ratings place a result against an HMI reference built from monitoring results and ordinary-setting medians for the same form and basis. Same-study contrasts compare a contaminated or treated site with its control, targeted with random sampling, a prepared form with the unprocessed one, or one group of a study with the median of its other groups. Held rows failed a check against their own source and are shown but not compared.

Methods

HMI pools subgroup medians for lamb chop, as sold on a as sold, as eaten or fresh weight basis: monitoring results summarized as one median per reporting region, sampling type and collection year, total diet composites and printed sample values as single observations, and printed subgroup medians from ordinary farms or markets. Each sampling family has equal total weight. Non-detects stay as zero-to-limit intervals, so quartiles carry lower and upper bounds. Means, ranges and maxima never enter as observations. Other forms, other bases, targeted sampling and results from mining, industrial, wastewater-affected, experimental, fertiliser or manufacturer settings are kept out of this reference.

Inverse weighted empirical CDF; midpoint at exact cumulative-weight boundaries. At least four reference units and a definitely positive Q1 to Q3 spread are required. This is a display eligibility rule, not statistical validation.

Limitations

WHO GEMS/Food is the only compatible sampling family for lamb chop, as sold on this basis in the completed lamb chop ledger, so this single-family reference cannot represent other markets. Reporting regions and purchase markets are not growing areas. Non-detects with differing limits widen the bounds. A position is descriptive concentration, not a safety or compliance judgment.

Methods

HMI pools subgroup medians for lamb chop, as sold on a basis not stated by the source basis: monitoring results summarized as one median per reporting region, sampling type and collection year, total diet composites and printed sample values as single observations, and printed subgroup medians from ordinary farms or markets. Each sampling family has equal total weight. Non-detects stay as zero-to-limit intervals, so quartiles carry lower and upper bounds. Means, ranges and maxima never enter as observations. Other forms, other bases, targeted sampling and results from mining, industrial, wastewater-affected, experimental, fertiliser or manufacturer settings are kept out of this reference.

Inverse weighted empirical CDF; midpoint at exact cumulative-weight boundaries. At least four reference units and a definitely positive Q1 to Q3 spread are required. This is a display eligibility rule, not statistical validation.

Limitations

WHO GEMS/Food is the only compatible sampling family for lamb chop, as sold on this basis in the completed lamb chop ledger, so this single-family reference cannot represent other markets. Reporting regions and purchase markets are not growing areas. Non-detects with differing limits widen the bounds. A position is descriptive concentration, not a safety or compliance judgment.

How metals reach lamb chop

No study in the library compared lamb chop from contaminated and ordinary settings, so the routes by which metals reach it are not measured here.

Which forms and regions measured lower

The HMI reference for lead in lamb chop, as sold pools 50 subgroup units from 1 sampling family, with a median of below 10 µg/kg and a middle half spanning below 10 (lower quartile) and below 20 µg/kg (upper quartile).1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → For lead in lamb chop, oil, the reference median was below 4 µg/kg, with a middle half from below 4 to below 4 µg/kg across 27 units.2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source → For cadmium in lamb chop, as sold, the reference median was below 5 µg/kg, with a middle half from below 2 to below 6 µg/kg across 58 units.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →

Among GEMS/Food reporting regions, lamb chop, as sold had the lowest cadmium subgroup median in EURO (31.5 µg/kg) and the highest in EURO (90 µg/kg); reporting regions are markets, not growing areas.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →

Processing, cooking and preparation

Processed or prepared forms were compared only with unprocessed lamb chop in the same study and group. Lamb chop, cooked (5 city composites) had lead lower at 8.6 µg/kg, against 9.2 µg/kg for the unprocessed form in the same group (lamb chop, as sold).6Dabeka RW, McKenzie AD · 1995Survey of Lead, Cadmium, Fluoride, Nickel, and Cobalt in Food Composites and Estimation of Dietary Intakes of These Elements by Canadians in 1986-1988Journal of AOAC InternationalRead source →

Forms differ in water content, so a per-kilogram difference is not by itself a measured removal or gain of metal.

Mitigation for lamb chop

Lot testing against the applicable limit is the check that can be verified.

No measured way to lower metals in this food is in the library yet.

Trade-offs and limits of controls

Metals do not move together, so a lot that passes a lead limit says little about cadmium, arsenic or nickel unless those are tested as well.

Testing lamb chop for metals

Results depend on the method and its reporting limit. Reporting limits for lead ranged from 2 µg/kg (WHO GEMS/Food) to 5,000 µg/kg (WHO GEMS/Food), so a non-detect from a less sensitive method says much less.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → Reporting limits for cadmium ranged from 0.8 µg/kg (WHO GEMS/Food) to 1,000 µg/kg (WHO GEMS/Food), so a non-detect from a less sensitive method says much less.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → Reporting limits for total arsenic ranged from 3 µg/kg (FDA Total Diet Study) to 100 µg/kg (WHO GEMS/Food), so a non-detect from a less sensitive method says much less.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →

A useful lot result names the form, the basis and a quantification limit well below the limit that applies.

Buying and verifying lamb chop

No maximum level for metals in lamb chop was verified from primary text for this page; buyers should confirm the limit that applies in the destination market.

Exposure from lamb chop

No source in the library converted lamb chop concentrations into a verified estimate of intake for a defined population. Concentrations describe the food, not individual risk.

Evidence review and remaining gaps

Every source record that names lamb chop was decided on its content: 9 occurrence extracted, 9 records in all. The occurrence table renders every extracted result; held values remain visible with their reason.

References identify the sources used in these answers. The Sources index preserves additional discovery links; inclusion there does not mean a source has been reviewed for this assessment. Corrections, completed searches, new direct evidence and changes in requirements should reopen the relevant answer.

Does processing change heavy metals in lamb chop?

Only comparisons between forms in the same study are available, not before-and-after measurements of the same lamb chop.6Dabeka RW, McKenzie AD · 1995Survey of Lead, Cadmium, Fluoride, Nickel, and Cobalt in Food Composites and Estimation of Dietary Intakes of These Elements by Canadians in 1986-1988Journal of AOAC InternationalRead source → Lamb chop, cooked (5 city composites) had lead lower at 8.6 µg/kg, against 9.2 µg/kg for the unprocessed form in the same group (lamb chop, as sold).6Dabeka RW, McKenzie AD · 1995Survey of Lead, Cadmium, Fluoride, Nickel, and Cobalt in Food Composites and Estimation of Dietary Intakes of These Elements by Canadians in 1986-1988Journal of AOAC InternationalRead source →

How much of the arsenic in lamb chop is inorganic?

Inorganic arsenic, the more toxic form, was measured in 5 results from 3 sources, far fewer than total arsenic.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →3Marín S, Pardo O, Sánchez A, Sanchis Y, Vélez D, Devesa V, Font G, Yusà V · 2018Assessment of metal levels in foodstuffs from the Region of Valencia (Spain)Toxicology Reports 5 (2018) 654-670Read source →5Baxter M, Brereton N · 2015Total Diet Study of metals and other elements in foodFood and Environment Research Agency report for the UK Food Standards Agency, Fera report 15/06, project FS102081Read source → Marín et al. 2018 reported inorganic arsenic at 0.3 µg/kg (mean) in lamb chop, as sold from Meat and meat products group, Region of Valencia TDS 2010-2011.3Marín S, Pardo O, Sánchez A, Sanchis Y, Vélez D, Devesa V, Font G, Yusà V · 2018Assessment of metal levels in foodstuffs from the Region of Valencia (Spain)Toxicology Reports 5 (2018) 654-670Read source →
