Across 2 other studies of ordinary farms and markets, reported lead means and medians on an as-sold or fresh-weight basis ranged from 2.6 µg/kg (Spungen et al. 2024) to 10 µg/kg (Gavelek et al. 2019).3Lead exposures in older children (males and females 7-17 years), women of childbearing age (females 16-49 years) and adults (males and females 18+ years): FDA total diet study 2014-16Food Additives & Contaminants: Part ARead source →4Infants’ and young children’s dietary exposures to lead and cadmium: FDA total diet study 2018-2020Food Additives & Contaminants: Part ARead source → Spungen et al. 2024 reported cadmium at 29 µg/kg (mean) in english muffin, as sold from all samples.4Infants’ and young children’s dietary exposures to lead and cadmium: FDA total diet study 2018-2020Food Additives & Contaminants: Part ARead source →
For a buyer the practical points are the form bought, the basis a result is reported on, where the english muffin came from and the laboratory’s reporting limit. Testing finds contamination but does not remove it.
What counts as english muffin
This page covers english muffin in 2 forms kept separate in every comparison: english muffin, as sold (13 results) and english muffin, cooked (2 results).1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →2FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →3Lead exposures in older children (males and females 7-17 years), women of childbearing age (females 16-49 years) and adults (males and females 18+ years): FDA total diet study 2014-16Food Additives & Contaminants: Part ARead source →4Infants’ and young children’s dietary exposures to lead and cadmium: FDA total diet study 2018-2020Food Additives & Contaminants: Part ARead source →5Children’s exposures to lead and cadmium: FDA total diet study 2014-16Food Additives & Contaminants: Part ARead 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 english muffin
The table holds every extracted english muffin result: one row for each statistic a source reports for a form, group and metal, 15 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.1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →2FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →3Lead exposures in older children (males and females 7-17 years), women of childbearing age (females 16-49 years) and adults (males and females 18+ years): FDA total diet study 2014-16Food Additives & Contaminants: Part ARead source →4Infants’ and young children’s dietary exposures to lead and cadmium: FDA total diet study 2018-2020Food Additives & Contaminants: Part ARead source →5Children’s exposures to lead and cadmium: FDA total diet study 2014-16Food Additives & Contaminants: Part ARead 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.1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →
6 rows can be rated against an HMI reference for the same form and basis, 1 row have a direct same-study comparison, and the rest stay unrated with the reason recorded.
Comparison methods and scope
Each row is one statistic a source reports for one form of english muffin, 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.
First displayed analyte: Lead: 6 findings from 5 sources. Each row retains its statistic and measurement basis.

| Contributing family | Reference units | Weight |
|---|---|---|
| WHO GEMS/Food | 12 | 50% |
| FDA Total Diet Study | 27 | 50% |
Methods
HMI pools subgroup medians for english muffin, 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
2 sampling families with different designs; none is a probability sample of world supply. 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.

The reference is computed by HMI from admitted evidence, not copied from a study baseline. It describes the evidence currently in this scope; it is not a worldwide or current-lot benchmark. Source, year and region filters do not change it. Different HMI scopes are not one common ranking.
The result is below a reporting limit, and the range from zero to that limit crosses more than one band.
The result is on a basis (dry weight, or not stated) that no HMI reference for this form uses, so it cannot be placed.
Reporting limits overlap the study comparison, so no direction can be shown.
No findings match these filters. Change the selection or reset to show all source findings.
How metals reach english muffin
No study in the library compared english muffin 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 english muffin, as sold pools 39 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 10 µg/kg (upper quartile).1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →2FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source → For cadmium in english muffin, as sold, the reference median was 25 µg/kg, with a middle half from 23 to 29.5 µg/kg across 34 units.1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →2FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source → For total arsenic in english muffin, as sold, the reference median was 4.4 µg/kg, with a middle half from 3.9 to 6.5 µg/kg across 27 units.2FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →
Processing, cooking and preparation
Processed or prepared forms were compared only with unprocessed english muffin in the same study and group. English muffin, cooked (PAHO) had cadmium lower at 13.6 µg/kg, against 22 µg/kg for the unprocessed form in the same group (english muffin, as sold).1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →
Forms differ in water content, so a per-kilogram difference is not by itself a measured removal or gain of metal.
Mitigation for english muffin
No control for metals in english muffin 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 english muffin; 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 english muffin for metals
Results depend on the method and its reporting limit. Reporting limits for lead ranged from 1 µg/kg (WHO GEMS/Food) to 3,000 µg/kg (WHO GEMS/Food), so a non-detect from a less sensitive method says much less.1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → Reporting limits for cadmium were 1 µg/kg where sources stated them.2FY2018-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 english muffin
No maximum level for metals in english muffin was verified from primary text for this page; buyers should confirm the limit that applies in the destination market.
Exposure from english muffin
No source in the library converted english muffin 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 english muffin was decided on its content: 5 occurrence extracted, 5 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 english muffin?
Only comparisons between forms in the same study are available, not before-and-after measurements of the same english muffin.1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → English muffin, cooked (PAHO) had cadmium lower at 13.6 µg/kg, against 22 µg/kg for the unprocessed form in the same group (english muffin, as sold).1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →
