MRE pouches: BPA-free since 2015 (DOD requirement), but earlier stocks may contain BPA liner. Canned goods: BPA or BPA-alternative liners (BPS, BPF — not necessarily safer). Heavy metals in shelf-stable foods: lead and cadmium accumulate from processing equipment and can packaging over extended storage. Freeze-dried foods: lowest chemical migration concern but nutritional degradation over time. FEMA: replace canned emergency food every 1-2 years, freeze-dried every 5-25 years depending on packaging.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.5,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
