Oat ring cereal overview

Oat ring cereal in the HMI library has 143 reported results for lead, cadmium, total arsenic, inorganic arsenic, dimethylarsinic acid, monomethylarsonic acid, total mercury, nickel, chromium and uranium from 5 sources.^{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 →}^{3Alexandra Gavelek, Judith Spungen, Dana Hoffman-Pennesi, Brenna Flannery, Laurie Dolan, Sherri Dennis, Suzanne Fitzpatrick · 2019Lead 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 →}^{4Spungen 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 →}^{5U.S. Food and Drug Administration · 2016Analytical Results from Inorganic Arsenic in Rice Cereals for Infants, Non-Rice Infant Cereal and Other Foods Commonly Eaten by Infants and ToddlersU.S. Food and Drug AdministrationRead source →} WHO GEMS/Food submissions reported lead in oat ring cereal, as sold from 25 results in 1 reporting region, with subgroup medians below 10 µg/kg, mostly non-detects.^{1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →} In the US Total Diet Study, oat ring cereal, as sold had a median lead result of 6.6 µg/kg across 3 composites from 2018–2020.^{2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →}

Across 2 other studies of ordinary farms and markets, reported lead means and medians on an as-sold or fresh-weight basis ranged from 4.3 µg/kg (Spungen et al. 2024) to 7 µg/kg (Gavelek et al. 2019).^{3Alexandra Gavelek, Judith Spungen, Dana Hoffman-Pennesi, Brenna Flannery, Laurie Dolan, Sherri Dennis, Suzanne Fitzpatrick · 2019Lead 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 →}^{4Spungen 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 →} Spungen et al. 2024 reported cadmium at 20 µg/kg (mean) in oat ring cereal, as sold from all samples.^{4Spungen 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 a buyer the practical points are the form bought, the basis a result is reported on, where the oat ring cereal came from and the laboratory’s reporting limit. Testing finds contamination but does not remove it.

What counts as oat ring cereal

This page covers oat ring cereal, as sold (143 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 →}^{3Alexandra Gavelek, Judith Spungen, Dana Hoffman-Pennesi, Brenna Flannery, Laurie Dolan, Sherri Dennis, Suzanne Fitzpatrick · 2019Lead 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 →}^{4Spungen 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 →}^{5U.S. Food and Drug Administration · 2016Analytical Results from Inorganic Arsenic in Rice Cereals for Infants, Non-Rice Infant Cereal and Other Foods Commonly Eaten by Infants and ToddlersU.S. Food and Drug AdministrationRead 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 oat ring cereal

The table holds every extracted oat ring cereal result: one row for each statistic a source reports for a form, group and metal, 143 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 →}^{3Alexandra Gavelek, Judith Spungen, Dana Hoffman-Pennesi, Brenna Flannery, Laurie Dolan, Sherri Dennis, Suzanne Fitzpatrick · 2019Lead 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 →}^{4Spungen 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 →}^{5U.S. Food and Drug Administration · 2016Analytical Results from Inorganic Arsenic in Rice Cereals for Infants, Non-Rice Infant Cereal and Other Foods Commonly Eaten by Infants and ToddlersU.S. Food and Drug AdministrationRead 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 →}

13 rows can be rated against an HMI reference for the same form and basis, 67 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 oat ring cereal, 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 family	Reference units	Weight
WHO GEMS/Food	6	50%
FDA Total Diet Study	6	50%

Methods

HMI pools subgroup medians for oat ring cereal, 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

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.

How metals reach oat ring cereal

No study in the library compared oat ring cereal 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 oat ring cereal, as sold pools 12 subgroup units from 2 sampling families, with a median of between 4.7 and 6.5 µg/kg and a middle half spanning below 5.2 (lower quartile) and between 6.2 and 10 µg/kg (upper quartile).^{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 →} For cadmium in oat ring cereal, as sold, the reference median was 14.5 µg/kg, with a middle half from 12 to 16 µg/kg across 13 units.^{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 →} For total arsenic in oat ring cereal, as sold, the reference median was 24 µg/kg, with a middle half from 22 to 28 µg/kg across 6 units.^{2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →}

In one study, total arsenic across 30 groups of oat ring cereal ranged from 8.8 µg/kg (Sweetened Oat Cereal with Real Honey and Natural Almond Flavor) to 90 µg/kg (Whole Grain Rice and Corn); the lowest is the lowest observed in that study, not an established sourcing preference.^{5U.S. Food and Drug Administration · 2016Analytical Results from Inorganic Arsenic in Rice Cereals for Infants, Non-Rice Infant Cereal and Other Foods Commonly Eaten by Infants and ToddlersU.S. Food and Drug AdministrationRead source →}

Processing, cooking and preparation

No processing study for metals in this food is in the library yet.

Mitigation for oat ring cereal

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 oat ring cereal for metals

Results depend on the method and its reporting limit. Reporting limits for lead ranged from 4 µg/kg (FDA Total Diet Study) to 3,000 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 →}^{2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →} Reporting limits for cadmium were 1 µg/kg where sources stated them.^{2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →} Reporting limits for total arsenic were 3 µg/kg where sources stated them.^{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 oat ring cereal

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

Exposure from oat ring cereal

No source in the library converted oat ring cereal 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 oat ring cereal 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.

Oat ring cereal FAQs

What heavy metals are found in oat ring cereal?

Which origins or products of oat ring cereal measured lowest?

In one study, total arsenic across 30 groups of oat ring cereal ranged from 8.8 µg/kg (Sweetened Oat Cereal with Real Honey and Natural Almond Flavor) to 90 µg/kg (Whole Grain Rice and Corn); the lowest is the lowest observed in that study, not an established sourcing preference.^{5U.S. Food and Drug Administration · 2016Analytical Results from Inorganic Arsenic in Rice Cereals for Infants, Non-Rice Infant Cereal and Other Foods Commonly Eaten by Infants and ToddlersU.S. Food and Drug AdministrationRead source →}
