Furan: IARC Group 2B (possible carcinogen), hepatotoxic. Volatile: boils at 31C — opening a can or jar and heating food in an open pot releases most furan. Highest levels: roasted coffee (2000-4000 ppb), canned soups (50-100 ppb), jarred baby food (20-100 ppb). Baby food concern: EFSA identified jarred baby food as a significant furan exposure source for infants. FDA monitoring since 2004 — no regulatory limits. Mitigation: open container, transfer to pot, heat with lid off (furan volatilizes rapidly).","synthesis":{"derived_risk_level":"severe","synthesis_confidence":0.731,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"product_users","exposure_modifier":1.075,"vulnerability_escalated":true,"escalation_reason":"Infant 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]).

No FDA or EU regulatory limits — EFSA issued scientific opinion, EC monitoring recommendation. Mitigation is simple and effective: transfer food from can/jar to pot, heat uncovered. Microwave in sealed container: retains more furan (no ventilation).
