Cadmium Has No Kill Step · The October 2026 Baby-Food Proposal, the Limits of End-Product Testing, and the Case for Source-Controlled Formulation
Year: 2026
Type: article
Abstract: The US Food and Drug Administration's October 2026 draft action levels for cadmium in processed foods for children under two years of age mark a consequential shift from general concern about toxic elements to category-specific manufacturing decisions. The proposed concentrations range from 10 to 45 µg/kg, yet they are neither binding final limits nor interchangeable with the European Union's existing maximum levels. More importantly, cadmium is an elemental contaminant: ordinary cooking and microbial lethality steps do not destroy it, while peeling, fractionation, drying and ingredient substitution can redistribute its mass and change measured concentration. This article integrates the FDA's underlying exposure and achievability analysis with crop uptake science, analytical uncertainty, food-process mass balances, bioaccessibility research and comparative EU–Spain–UK–US law. It identifies where end-product testing is necessary but insufficient and develops a testable, source-to-serving qualification approach. The proposed framework is a research and industrial validation agenda, not a proven decontamination technology or a substitute for statutory controls.
