Bisphenol A in canned foods

Abstract

Bisphenol A (BPA) is a chemical used in the production of polycarbonate and epoxy resins. Food and beverage packaging, especially metal cans, may be internally coated with epoxy resins containing BPA to protect food from direct contact with packaging material. Results from a targeted survey of 391 samples of canned pastas, soups, vegetables, infant formulas, beverages, fruits, pie fillings, and curry products showed 35.5 per cent of samples did not contain detectable levels of BPA. This targeted survey had similar detection rates to previous CFIA surveys, international studies, and the National Chemical Residue Monitoring Program data. Health Canada evaluated the data and determined that levels of BPA found in the remaining samples did not pose a risk to human health; therefore, no follow up actions were needed.
