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

What counts as kidney beans

This page covers kidney beans in 3 forms kept separate in every comparison: kidney beans, as sold (88 results), kidney beans, dried (18 results) and kidney beans, canned (11 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 →3Al Othman ZA · 2010Lead Contamination in Selected Foods from Riyadh City Market and Estimation of the Daily IntakeMolecules 2010, 15, 7482-7497Read source →4Unknown authors · 2020Eid et al.: Evaluating the uptake of ten heavy metals by kidney bean (Phaseolus vulgaris L.) grown in a soil-sludge mixture using aPeer-reviewed articleRead source →5Unknown authors · 2017Levels, dietary intake, and health risk of potentially toxic metalsPeer-reviewed articleRead source →6Yu S, Pan XD, Han JL · 2023Toxic Elements in Beans from Zhejiang, Southeast China: Distribution and Probabilistic Health Risk AssessmentFoodsRead 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 kidney beans

The table holds every extracted kidney beans result: one row for each statistic a source reports for a form, group and metal, 117 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 →3Al Othman ZA · 2010Lead Contamination in Selected Foods from Riyadh City Market and Estimation of the Daily IntakeMolecules 2010, 15, 7482-7497Read source →4Unknown authors · 2020Eid et al.: Evaluating the uptake of ten heavy metals by kidney bean (Phaseolus vulgaris L.) grown in a soil-sludge mixture using aPeer-reviewed articleRead source →5Unknown authors · 2017Levels, dietary intake, and health risk of potentially toxic metalsPeer-reviewed articleRead source →6Yu S, Pan XD, Han JL · 2023Toxic Elements in Beans from Zhejiang, Southeast China: Distribution and Probabilistic Health Risk AssessmentFoodsRead 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 →

1 row can be rated against an HMI reference for the same form and basis, 2 rows have a direct same-study comparison, and the rest stay unrated with the reason recorded. 5 values from 1 source failed a check against their own source and are shown but not compared.6Yu S, Pan XD, Han JL · 2023Toxic Elements in Beans from Zhejiang, Southeast China: Distribution and Probabilistic Health Risk AssessmentFoodsRead source →

Comparison methods and scope

Each row is one statistic a source reports for one form of kidney beans, 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.

Contributing familyReference unitsWeight
WHO GEMS/Food10100%

Methods

HMI pools subgroup medians for kidney beans, 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–Q3 spread are required. This is a display eligibility rule, not statistical validation.

Limitations

WHO GEMS/Food is the only compatible sampling family for kidney beans, as sold on this basis in the completed kidney beans 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 kidney beans, dried 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–Q3 spread are required. This is a display eligibility rule, not statistical validation.

Limitations

Yu et al. 2023 is the only compatible sampling family for kidney beans, dried on this basis in the completed kidney beans 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 kidney beans

No study in the library compared kidney beans 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 kidney beans, canned pools 4 subgroup units from 2 sampling families, with a median of below 4 µg/kg and a middle half spanning below 4 (lower quartile) and below 4 µg/kg (upper quartile).2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →7Spungen JH, et al. · 2024Infants’ and young children’s dietary exposures to lead and cadmium: FDA total diet study 2018-2020Food Additives & Contaminants: Part ARead source → For lead in kidney beans, as sold, the reference median was between 0.9 and 22.5 µg/kg, with a middle half from below 2.2 to between 3.1 and 40 µg/kg across 10 units.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → For lead in kidney beans, as sold, the reference median was below 5.08 µg/kg, with a middle half from below 5 to between 2.58 and 7.58 µg/kg across 4 units.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →

Among GEMS/Food reporting regions, kidney beans, as sold had the lowest lead subgroup median in WPRO (0.599 µg/kg) and the highest in PAHO (3.1 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 kidney beans in the same study and group. Kidney beans, canned (Legume, Riyadh city markets, May 2009) had lead lower at 47 µg/kg, against 55 µg/kg for the unprocessed form in the same group (kidney beans, as sold).3Al Othman ZA · 2010Lead Contamination in Selected Foods from Riyadh City Market and Estimation of the Daily IntakeMolecules 2010, 15, 7482-7497Read source →

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

Mitigation for kidney beans

No control for metals in kidney beans was measured in the library; lot testing against the applicable limit remains the verifiable step.

No study in this library has yet measured a way to lower heavy metals in kidney beans; the results above show the levels measured, and lot testing against the applicable limit remains the verifiable check.

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 kidney beans for metals

Results depend on the method and its reporting limit. Reporting limits for lead ranged from 0.04 µg/kg (WHO GEMS/Food) to 45 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 1 µg/kg (FDA Total Diet Study) to 10 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 → Reporting limits for total arsenic ranged from 3 µg/kg (FDA Total Diet Study) to 60 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 kidney beans

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

Exposure from kidney beans

No source in the library converted kidney beans 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 kidney beans was decided on its content: 8 occurrence extracted, 8 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.
