False positives reclassified P1→P5 (12)
The triage manifest’s P1 heuristic (concentration keywords + food matrix + metal in first 4000 chars) produced false positives. These papers were screened and found not to be Path A concentration candidates:

Note: tAs in fish purees (henriquez-hernandez2023) is dominated by organic arsenobetaine from seafood; do not apply to iAs threshold calculations.
Notable findings
Lead adulteration vs background contamination: The WanaBana recall (napier2024) demonstrates that Pb in fruit pouches can be 190–580× FDA action level due to deliberate adulteration of cinnamon with lead chromate. This is distinct from background agricultural Pb in apple puree. HMT&C spice sourcing protocols need to address lead chromate adulteration risk.
Arsenic surge at rice cereal introduction: Signes-Pastor 2018 documents a 480% increase in urinary DMA when rice cereal was introduced at weaning, with Spearman ρ=0.90 correlation between rice cereal intake and total urinary arsenic. This is the strongest biomarker evidence directly linking rice cereal to infant As exposure.
Brown rice syrup concentrates iAs: Jackson 2012 found OBRS iAs 51–89% of total As (vs more balanced in whole rice), with toddler formula containing OBRS reaching 15–25 µg/L iAs (reconstituted). Flag OBRS as a high-iAs ingredient in formula and cereal bar products.
Breast milk metals — geographic extremes: Bihar India (Kumar 2024) shows 55% of mothers with breast milk As above WHO limit (up to 458 µg/L); Sub-Saharan Africa (Onyena 2024) shows Cd 56× and Pb 13× higher in breast milk than Mediterranean Europe. These reflect environmental contamination extremes, not food product safety.
Breastfeeding as protective factor: Fångström 2008, Islam 2014, and Carignan 2015 all confirm that exclusive breastfeeding substantially reduces infant As exposure versus formula feeding, even when mothers have elevated As exposure. The key modifiable risk for formula-fed infants is preparation water quality.
Open questions
-
FM_11971891 (kumar2025 Hg Bihar): Full concentration tables not available from Marker excerpt. A detailed read of the full paper is needed to extract specific breast milk Hg mean/median values.
-
FM_10379829 (price2023 biokinetic modeling): Specific blood Pb model outputs not extracted; needs full paper read to extract modeled blood Pb distributions for US infant age groups.
-
P2 tier (488 papers): Ready to begin after this commit.
