Doughnut overview

For a buyer the practical points are the form bought, the basis a result is reported on, where the doughnut came from and the laboratory’s reporting limit. Testing finds contamination but does not remove it.
What counts as doughnut
This page covers doughnut in 2 forms kept separate in every comparison: doughnut, as sold (9 results) and doughnut, 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 →3Infants’ and young children’s dietary exposures to lead and cadmium: FDA total diet study 2018-2020Food 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 doughnut
The table holds every extracted doughnut result: one row for each statistic a source reports for a form, group and metal, 11 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 →3Infants’ and young children’s dietary exposures to lead and cadmium: FDA total diet study 2018-2020Food 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 →
1 row can be rated against an HMI reference for the same form and basis, 0 rows 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 doughnut, 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: 2 findings from 2 sources. Each row retains its statistic and measurement basis.

3 reference units; 1 sampling family. Counts describe evidence units, not independent studies or certainty.
| Contributing family | Reference units | Weight |
|---|---|---|
| FDA Total Diet Study | 3 | 100% |
Methods
HMI pools subgroup medians for doughnut, 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
FDA Total Diet Study is the only compatible sampling family for doughnut, as sold on this basis in the completed doughnut 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 doughnut
No study in the library compared doughnut 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 cadmium in doughnut, cooked pools 7 subgroup units from 1 sampling family, with a median of 14 µg/kg and a middle half spanning 12 (lower quartile) and 18.5 µg/kg (upper quartile).1GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →
Processing, cooking and preparation
No processing study for metals in this food is in the library yet.
Mitigation for doughnut
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 doughnut for metals
Results depend on the method and its reporting limit. Reporting limits for lead were 4 µg/kg where sources stated them.2FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source → Reporting limits for cadmium were 1 µg/kg where sources stated them.2FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source → Reporting limits for total mercury ranged from 1 µg/kg (FDA Total Diet Study) to 20 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 →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 doughnut
No maximum level for metals in doughnut was verified from primary text for this page; buyers should confirm the limit that applies in the destination market.
Exposure from doughnut
No source in the library converted doughnut 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 doughnut was decided on its content: 3 occurrence extracted, 3 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.
