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

What counts as fish fingers

This page covers fish fingers in 2 forms kept separate in every comparison: fish fingers, as sold (41 results) and fish fingers, cooked (9 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 →3Naess S, Aakre I, Lundebye AK, Ornsrud R, Kjellevold M, Markhus MW, Dahl L · 2020Mercury, lead, arsenic, and cadmium in Norwegian seafood products and consumer exposureFood Additives & Contaminants: Part BRead 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 →5German Federal Institute for Risk Assessment (BfR) · 2024Methylmercury in fish and seafood – health risk assessment of new data from the BfR MEAL studyBfR Opinion 023/2024Read 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 fish fingers

The table holds every extracted fish fingers result: one row for each statistic a source reports for a form, group and metal, 50 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 →3Naess S, Aakre I, Lundebye AK, Ornsrud R, Kjellevold M, Markhus MW, Dahl L · 2020Mercury, lead, arsenic, and cadmium in Norwegian seafood products and consumer exposureFood Additives & Contaminants: Part BRead 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 →5German Federal Institute for Risk Assessment (BfR) · 2024Methylmercury in fish and seafood – health risk assessment of new data from the BfR MEAL studyBfR Opinion 023/2024Read 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 →

18 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 fish fingers, 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.

34 reference units; 1 sampling family. Counts describe evidence units, not independent studies or certainty.

Contributing familyReference unitsWeight
WHO GEMS/Food34100%

Methods

HMI pools subgroup medians for fish fingers, 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

WHO GEMS/Food is the only compatible sampling family for fish fingers, as sold on this basis in the completed fish fingers 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.

HMI pools subgroup medians for fish fingers, cooked 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 fish fingers, cooked on this basis in the completed fish fingers 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 fish fingers

No study in the library compared fish fingers 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 fish fingers, as sold pools 34 subgroup units from 1 sampling family, with a median of below 10 µg/kg and a middle half spanning below 10 (lower quartile) and below 20 µg/kg (upper quartile).1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → For cadmium in fish fingers, as sold, the reference median was between 7.5 and 8.5 µg/kg, with a middle half from between 2.5 and 5.5 to between 9 and 10 µg/kg across 29 units.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → For total arsenic in fish fingers, as sold, the reference median was 946 µg/kg, with a middle half from 724 to 1,270 µg/kg across 13 units.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →

Among GEMS/Food reporting regions, fish fingers, as sold had the lowest cadmium subgroup median in PAHO (9 µg/kg) and the highest in EURO (12 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 → For total arsenic, the lowest regional median was in EURO (268 µg/kg) and the highest in EURO (1,450 µg/kg).1World Health Organization · 2026GEMS/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 fish fingers

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 fish fingers for metals

Results depend on the method and its reporting limit. Reporting limits for lead ranged from 2 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.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 2 µg/kg (WHO GEMS/Food) to 3 µg/kg (FDA Total Diet Study), 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 fish fingers

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

Exposure from fish fingers

No source in the library converted fish fingers 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 fish fingers 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.

Fish fingers FAQs

What heavy metals are found in fish fingers?

The library reports lead, cadmium, total arsenic, inorganic arsenic, total mercury, methylmercury, nickel, chromium and uranium in fish fingers, most often lead, cadmium and total arsenic.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 →3Naess S, Aakre I, Lundebye AK, Ornsrud R, Kjellevold M, Markhus MW, Dahl L · 2020Mercury, lead, arsenic, and cadmium in Norwegian seafood products and consumer exposureFood Additives & Contaminants: Part BRead 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 → WHO GEMS/Food submissions reported lead in fish fingers, as sold from 169 results in 3 reporting regions, with a subgroup median of 2.8 µg/kg.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →

Which regions report the lowest levels in fish fingers?

Among GEMS/Food reporting regions, fish fingers, as sold had the lowest cadmium subgroup median in PAHO (9 µg/kg) and the highest in EURO (12 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 → For total arsenic, the lowest regional median was in EURO (268 µg/kg) and the highest in EURO (1,450 µg/kg).1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →

How much of the arsenic in fish fingers is inorganic?

Inorganic arsenic, the more toxic form, was measured in 1 result from 1 source, far fewer than total arsenic.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source → WHO GEMS/Food submissions reported inorganic arsenic in fish fingers, as sold from 2 results in 1 reporting region, with subgroup medians below 11.9 µg/kg, mostly non-detects.1World Health Organization · 2026GEMS/Food Contaminants database heavy-metal exportsGEMS/Food Contamination Monitoring and Assessment ProgrammeRead source →
