Crisped rice cereal overview

Crisped rice cereal in the HMI library has 14 reported results for lead, cadmium, total arsenic, inorganic arsenic, total mercury, nickel, chromium and uranium from 4 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 →}^{3Spungen 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 →}^{4U.S. Food and Drug Administration · 2022Total Diet Study Report: Fiscal Years 2018-2020 Elements DataU.S. Food and Drug Administration, Total Diet Study ProgramRead source →} WHO GEMS/Food submissions reported lead in crisped rice cereal, as sold from 24 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, crisped rice cereal, as sold had a median lead result below 4 µg/kg across 3 composites from 2018–2020.^{2U.S. Food and Drug Administration · 2022FY2018-FY2020 TDS Elements Analytical ResultsFDA Total Diet StudyRead source →}

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

What counts as crisped rice cereal

This page covers crisped rice cereal, as sold (14 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 →}^{3Spungen 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 →}^{4U.S. Food and Drug Administration · 2022Total Diet Study Report: Fiscal Years 2018-2020 Elements DataU.S. Food and Drug Administration, Total Diet Study ProgramRead 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 crisped rice cereal

The table holds every extracted crisped rice cereal result: one row for each statistic a source reports for a form, group and metal, 14 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 →}^{3Spungen 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 →}^{4U.S. Food and Drug Administration · 2022Total Diet Study Report: Fiscal Years 2018-2020 Elements DataU.S. Food and Drug Administration, Total Diet Study ProgramRead 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 →}

3 rows 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 crisped rice 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.

Methods

HMI pools subgroup medians for crisped rice 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 crisped rice cereal

No study in the library compared crisped rice 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 crisped rice cereal, as sold pools 9 subgroup units from 2 sampling families, with a median of below 4.25 µg/kg and a middle half spanning below 4 (lower quartile) and between 0.75 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 crisped rice cereal, as sold, the reference median was 12 µg/kg, with a middle half from 10 to 14 µg/kg across 10 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 →}

Processing, cooking and preparation

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

Mitigation for crisped rice 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 crisped rice 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 →}

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

Buying and verifying crisped rice cereal

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

Exposure from crisped rice cereal
