Pork — HMTc Standard

Standard

The Heavy Metal Tested & Certified heavy-metal-safety standard for pork in Meat, Poultry, and Eggs, evaluated on as sold, raw or cooked edible portion (wet weight); bone and inedible fat excluded; no dry-to-wet or reconstitution conversion is performed. 4 of 11 panel analytes publish a numeric limit taken from the strictest applicable government maximum; the remainder are held under mandatory control or a substantiated not-material determination.

How every number on this page is set

Category-specific method notes. (1) MUSCLE MEAT vs OFFAL. Every credible instrument writes separate and materially looser maximum levels for edible offal, because lead and cadmium concentrate in liver and kidney. Every row here is scoped to muscle meat and attached edible fat; offal of the same species is a separately-tested sub-lot assessed against that species' offal maximum levels, and no offal value anchors a muscle-meat row. The taxonomy boundary rule places offal inside the animal's own subcategory, which is honoured by sub-lot testing rather than by publishing an offal-derived ceiling. (2) THE CATEGORY 1 BOUNDARY. Products marketed for ages 0-5 route to Category 1 (mixed meals), so the infant and baby-food action levels and maximum levels that would otherwise be the strictest values in the register are excluded by applicability from every row here, and are excluded explicitly in each row's audit_exclude_scope. (3) GAME AND LEAD AMMUNITION. Fragmenting lead projectiles are a documented, mechanical lead pathway in wild-harvested game. That evidence drives mandatory radiographic fragment screening before grinding and priority surveillance on the game row; it does not and cannot move the number, which remains a disclosed read-across from the domestic-mammal muscle-meat maximum level. (4) BASIS TREATMENT ON THE THREE COMPOSITE ROWS, DISCLOSED IN THE DIRECTION IT CUTS. On the processed-meat, canned-meat and analogue rows the component maximum level is applied to the finished product as sold, with no invented conversion factor. This config does NOT claim that treatment is conservative, because it is not: a formulation that is part water, brine, starch or rusk can carry a higher concentration in its meat or protein fraction than the component maximum level itself allows. The gap is closed by a second, independent obligation rather than by a conversion factor. Certification of those three rows requires documented compliance of the raw material or source commodity against the same named component maximum levels, in their own basis, IN ADDITION to finished-product compliance against the published ceiling; neither test substitutes for the other. The eggs row runs the opposite way and is treated accordingly: dried and powdered egg is concentrated relative to whole egg, so applying the whole-egg maximum level to the powder as sold is the STRICTER treatment, and it is applied without being reversed. (5) REGISTER GAPS ARE DISCLOSED, NOT FILLED. The EU 2023/915 and Codex CXS 193 lead rows for meat and offal, the EU and Codex cadmium offal rows, and the FSANZ cadmium meat and offal rows are absent from this register. They are recorded as register gaps for ingestion through the verified regulatory-fetch pathway and are NOT written into this config from memory. No absent row is assigned a remembered value anywhere in this config. Because the method selects the strictest applicable value, ingesting a missing row can only lower a published cell or leave it unchanged, never raise it; every affected cell must be re-derived when the missing rows land.

Master Limit Table

All values in ppb (µg/kg), as-sold basis. 4 of 11 analytes carry a firm ceiling; the remainder are governed by mandatory control or reflex-speciation screening with no standalone number, itemised in the derivation below. A brand meeting every firm value on a like-for-like basis, and passing every control, qualifies for the mark.

Tier 1 (Pb, iAs, Hg, MeHg, Cd) are zero-tolerance toxics with no established safe threshold. Tier 2 (tAs, Cr-VI, Ni, Sn, Al, Cr) carry a 150% transitional allowance under the program’s Status A–E framework.

Derivation — every government’s number, side by side

The full derivation for Pork. Each row lists every government maximum level in force worldwide, converted to the as-sold basis; the HMTc limit is the strictest of them, and the last column names which sovereign law binds. A blank cell means that government sets no limit for this analyte in this product.

All values µg/kg (ppb), as-sold basis. ² no government regulates this analyte for this exact product form: the value is a disclosed read-across from the nearest applicable government maximum, and the derivation names the instrument it comes from. It is never taken from occurrence data. After publication the standards ratchet may tighten it, using certified-lot results only. ³ not material in this matrix: controlled by reflex speciation or packaging control, not a standalone number. &sup4; no sovereign maximum exists for this analyte in this product, but a credible exposure pathway does — it is screened on every lot under ALARA against the tightest analogous reference, not assigned an invented number.

Occurrence and derivation rationale

For each analyte on the panel: what the peer-reviewed and survey literature measured in this category, cited one way to the Heavy Metal Index, and the Method v2.0 reasoning behind the certification limit — including, where no government sets a number, why the program sets one anyway. Occurrence figures are literature findings; the derivation is the certifier's.

Lead

2 studies in the certified-market pool measured lead in Pork across 36 certified-market samples. The pooled distribution centres on a median of 825 ppb and reaches 1.1 mg/kg at the 95th percentile. Hoha 2014, Paulsen 2015.

2 studies · 36 samples · median 825 ppb · P95 1.1 mg/kg

HMTc sets 100 ppb (regulatory-alignment): the strictest applicable government maximum level for this product form, adopted under Method v2.0 as the default certification standard. The certified-market pool's P97 is 1.2 mg/kg, at or above the government ceiling of 100 ppb, so the government maximum binds. Why lead is limited →

Total arsenic

3 studies in the corpus measured total arsenic in Pork (724 samples reported across those studies): Zhang 2022, Maikanov 2021, Liang 2019.

3 studies · 724 samples in the corpus

HMTc sets 500 ppb (regulatory-alignment): the strictest applicable government maximum level for this product form, adopted under Method v2.0 as the default certification standard. Why total arsenic is limited →

Cadmium

1 study in the certified-market pool measured cadmium in Pork across 36 certified-market samples. The pooled distribution centres on a median of 170 ppb and reaches 224 ppb at the 95th percentile. Hoha 2014.

1 study · 36 samples · median 170 ppb · P95 224 ppb

HMTc sets 50 ppb (regulatory-alignment): the strictest applicable government maximum level for this product form, adopted under Method v2.0 as the default certification standard. The certified-market pool's P97 is 231 ppb, at or above the government ceiling of 50 ppb, so the government maximum binds. Why cadmium is limited →

The corpus holds 2 measurements of nickel in Pork (118 samples reported across those studies), which the determination below is tested against: Buba 2020, Paulsen 2015.

2 studies · 118 samples in the corpus

HMTc sets no standalone nickel limit for Pork. No credible sovereign government sets a nickel maximum level for meat of cattle, pig, goat, sheep or any other terrestrial mammal. The EU nickel maximum levels recorded on the register (the eu2024_ni_* family) are drawn exclusively over plant matrices — cereals, pulses, legume, leafy and root vegetables, tree nuts, oilseeds, cocoa — and the only other credible nickel values are drinking-water statutory limits and a food-contact specific-migration limit, both in bases that cannot govern the content of a food. A plant-commodity nickel maximum level is not a supportable near-neighbour for animal muscle tissue, which accumulates nickel by a different route and at a different order of magnitude, so no read-across is available and no ceiling is invented. The analyte is controlled by Total nickel by ICP-MS on every certified lot, trended per SKU and per production line. Escalation is triggered by a result above the SKU's established rolling upper control limit, or by an increasing trend across three consecutive lots, and directs the investigation to nickel-bearing stainless contact surfaces (grinders, mincers, brine injectors, forming plates). No numeric ceiling is published because no sovereign instrument compels one, not a standalone number. Why nickel is limited →
