Unlike canned vegetables or simple fruits, RTE meals contain acidic, high-fat, or high-protein matrices that aggressively leach BPA and its replacements from epoxy can linings. The FDA-regulated epoxy linings that prevent corrosion and extend shelf life are typically derived from bisphenol A diglycidyl ether (BADGE), with migration rates that increase with acidity, fat content, temperature during retort sterilization, and storage time. Tomato-based products (soups, chili, pasta sauce) are consistently the highest BPA-migrating canned foods due to their low pH. This product category also carries concerns about sodium, but the chemical hazard focus here is BPA and its substitutes (BPS, BPF), which are endocrine-active at low doses. The FDA's 2012 action to end BPA in baby bottles did not restrict BPA in adult food cans, and the US still has no regulatory limit for BPA in food can linings — leaving bisphenol migration entirely to manufacturer decisions and voluntary reformulation.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.624,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"product_users","exposure_modifier":1.2,"vulnerability_escalated":true,"escalation_reason":"Infant exposure group","compounds_resolved":4,"compounds_total":4,"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]).
