This review on heavy metal certification for baby food links published measurements of arsenic, lead, mercury, and cadmium in infant foods to U.S. policy gaps, highlighting limited federal limits, variable manufacturer standards, FDA’s Closer to Zero plan, proposed legislative action levels, and third-party certification models.

The inorganic arsenic action level infant rice cereal guidance sets a 100 ppb benchmark, explains FDA’s enforcement posture, and shows surveillance data improving from 36% compliance (2011–2013) to 76% (2018), emphasizing sourcing and testing controls critical for certification.

codex-lead-maximum-levels define commodity-specific limits for total lead (Pb), informed by JECFA’s withdrawal of the former PTWI as non-protective. These MLs, portion rules, and category nuances can be translated into HMTC testing scopes, action limits, and supplier controls.

This heavy-metal-certification study found lead in all tested canned tomato paste, olives, and pickles, with mean Pb above the cited canned-food limit, while tin and other metals were low and mercury was not detected. It supports Pb-focused certification controls.

EFSA-metals-contaminants-in-food links metal sources, exposure drivers, vulnerable groups, and EU controls. It highlights why speciation (not total metal) matters for arsenic, why seafood and rice can drive risk, and how certification should map to EU maximum levels and official sampling/analysis rules.

This review links arsenic in poultry feed to potential inorganic arsenic exposure via meat residues and litter pathways, arguing U.S. oversight may lag evidence and consumption trends. It supports HMTC controls on arsenical additives, outcome testing, and litter management.

eu-food-heavy-metal-limits in EU 2023/915 sets enforceable maximum levels for metals (lead, cadmium, mercury, arsenic) and bans dilution-by-mixing. It defines how limits apply to edible portions and processed/compound foods—directly informing HMTC testing scope, sampling, and certification thresholds.

This study measured lead and cadmium in chicken tissues from Dhaka markets and modeled adult/child risks. Lead peaked in brain; cadmium peaked in liver. Non-cancer risk stayed <1, but multiple organs exceeded cited MACs, shaping how HMTC should define “tested.”

This tin-in-canned-foods study validates a mixed-micelle spectrofluorimetric method for measuring tin leached from tinplate packaging, achieving ng/mL detection, high precision, strong spike recoveries, and practical interference controls—features directly relevant to certification and regulatory monitoring of canned products.

This review compiles global evidence on As, Pb, Cd, and Hg in poultry, highlighting organ bioaccumulation, tissue damage, and a practical table of normal versus toxic concentrations in meat, organs, and eggs to inform HMTC testing priorities and thresholds.
