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

What counts as cottage cheese

Heavy metal contamination profile of cottage cheese

The table holds every extracted cottage cheese result: one row for each statistic a source reports for a form, group and metal, 107 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 →3Sarsembayeva NB, Abdigaliyeva TB, Utepova ZA, Biltebay AN, Zhumagulova SZ · 2020Heavy metal levels in milk and fermented milk products produced in the Almaty region, KazakhstanVeterinary World 13(4):609-613Read 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 →5Adilbekov Z, Mustafina R, Suleimenov S, Serikova A, Zhuzzassarova G, Suranshiyev Z, Bainiyazov A · 2026Technogenic contamination of livestock- and fish-derived food products with heavy metals and radionuclides in industrial and post-nuclear regions of KazakhstanVeterinary World 2026, 19(3): 1052-1068Read source →6Crupi R, Lo Turco V, Gugliandolo E, Nava V, Potortì AG, Cuzzocrea S, Di Bella G, Licata P · 2022Mineral Composition in Delactosed Dairy Products: Quality and Safety StatusFoods 2022, 11, 139Read 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 →

Comparison methods and scope

Each row is one statistic a source reports for one form of cottage cheese, 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.

Sarsembayeva et al. 2020825%
Spungen et al. 2024125%

Methods

HMI pools subgroup medians for cottage cheese, 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

4 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.

Methods

HMI pools subgroup medians for cottage cheese, 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

FDA Total Diet Study is the only compatible sampling family for cottage cheese, as sold on this basis in the completed cottage cheese 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 cottage cheese

No study in the library compared cottage cheese 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 cottage cheese, as sold pools 22 subgroup units from 4 sampling families, with a median of below 4 µg/kg and a middle half spanning below 4 (lower quartile) and between 4.45 and 10.1 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 →3Sarsembayeva NB, Abdigaliyeva TB, Utepova ZA, Biltebay AN, Zhumagulova SZ · 2020Heavy metal levels in milk and fermented milk products produced in the Almaty region, KazakhstanVeterinary World 13(4):609-613Read 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 → For cadmium in cottage cheese, as sold, the reference median was below 1.5 µg/kg, with a middle half from below 1 to between 22.6 and 49.7 µg/kg across 20 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 →3Sarsembayeva NB, Abdigaliyeva TB, Utepova ZA, Biltebay AN, Zhumagulova SZ · 2020Heavy metal levels in milk and fermented milk products produced in the Almaty region, KazakhstanVeterinary World 13(4):609-613Read 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 →

In one study, lead across 8 groups of cottage cheese ranged from 8.9 µg/kg (farm K, Almaty region (sample K/1-5-1-1)) to 16.2 µg/kg (farm A, Almaty region (sample A/1-5-1-5)); the lowest is the lowest observed in that study, not an established sourcing preference.3Sarsembayeva NB, Abdigaliyeva TB, Utepova ZA, Biltebay AN, Zhumagulova SZ · 2020Heavy metal levels in milk and fermented milk products produced in the Almaty region, KazakhstanVeterinary World 13(4):609-613Read source → In another study, total mercury across 8 groups of cottage cheese ranged from 40 µg/kg (producer C (code 9C)) to 230 µg/kg (producer A (code 7A)); the lowest is the lowest observed in that study, not an established sourcing preference.8Pankiewicz U · 2012Monitoring of total mercury level in selected dairy products from the south-east regions of PolandEcological Chemistry and Engineering ARead source →

Processing, cooking and preparation

No study in the library measured the same cottage cheese before and after washing, peeling, drying or cooking for metals, so no processing effect can be stated. Heat does not destroy metals; cooking or drying changes a concentration by moving water or metal, not by removing the element.

Mitigation for cottage cheese

No control for metals in cottage cheese 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 cottage cheese; 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 cottage cheese 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 ranged from 0.16 µg/kg (Dabeka et al. 1995) to 1,000 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 →7Dabeka RW, McKenzie AD · 1995Survey of Lead, Cadmium, Fluoride, Nickel, and Cobalt in Food Composites and Estimation of Dietary Intakes of These Elements by Canadians in 1986-1988Journal of AOAC InternationalRead source →

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

Buying and verifying cottage cheese

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

Exposure from cottage cheese

No source in the library converted cottage cheese 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 cottage cheese was decided on its content: 8 occurrence extracted, 8 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.
