EVIDENCE BOUNDARY & STANDARDS DISPOSITION

Breastmilk as a distinct exposure pathway

Keep maternal biomonitoring and lactation evidence outside food-product conformity claims while retaining it as vulnerable-population context for infant exposure communication.

The controlling scientific record is the public Heavy Metal Index synthesis, supported by 6 named anchor sources and expressed for Lead, Cadmium, Arsenic, Mercury, Aluminum, Chromium.

ICS does not reproduce the source extraction here. Keeping the evidence on the independent index preserves source-level methods, units, species, basis, uncertainty, and review state. This note records only the institutional consequence of that evidence.

Keep maternal biomonitoring and lactation evidence outside food-product conformity claims while retaining it as vulnerable-population context for infant exposure communication.

This disposition may change taxonomy, analyte coverage, test basis, surveillance priority, disclosure, or claim language. It does not allow a market occurrence percentile or a dramatic single study to become an initial certification value.

The finding is published in two additional authority layers: the HMI evidence record and the HMTc certification interpretation. Distribution should prioritize health professionals, regulators, journalists, consumer educators while preserving those distinct roles in headlines, briefings, interviews, and social posts.
