The wide use of bisphenol A (BPA) as a monomer in plastics manufacture or epoxy resins intended for food contact materials (FCM) has triggered numerous concerns due to toxicological findings indicating possible endocrine disrupting properties. This article traces the evolution of the scientific opinions since 1986 when the Tolerable Daily Intake (TDI) for BPA and its specific migration limit (SML) from plastic FCM into food were proposed for the first time by the Scientific Committee for Food (SCF). Resent extensive scientific studies concerning refined data on toxicity and exposure to BPA from food and non-food sources (eg. dust, cosmetics, thermal paper), including the most vulnerable groups of population, allowed the European Food Safety Authority (EFSA) to reduce the TDI of BPA from previously 50 μg/kg bw/day to now 4 μg/kg bw/day. EFSA’s latest scientific opinion published in 2015 concludes that basing on the current estimations of total exposure to BPA from dietary and non-dietary sources for infants, children and adolescents is below the temporary TDI of 4 μg/kg bw/day. EFSA has also underlined that BPA poses no health risk at the estimated exposure levels of any population age group, including unborn children and the elderly. However, EFSA has indicated that some data on exposure and toxicological effects still require clarifications.

Szerokie zastosowanie bisfenolu A (BPA) jako monomeru w produkcji tworzyw sztucznych i żywic epoksydowych przeznaczonych do kontaktu z żywnością wywołało wiele obaw wynikających z badań toksykologicznych wskazujących na możliwe szkodliwe działanie, szczególnie odnoszące się do efektów endokrynnych. W artykule przedstawiono ewolucję podejścia do BPA oraz kolejnych opinii naukowych od 1986 roku, kiedy Naukowy Komitet ds. Żywności (SCF) po raz pierwszy zaproponował dla BPA wartość tolerowanego dziennego pobrania (TDI) i limit migracji specyficznej (SML) tego związku do żywności z materiałów z tworzyw sztucznych przeznaczonych do kontaktu z żywnością. Obszerne piśmiennictwo naukowe dotyczące pogłębionych badań toksycznego działania i narażenia na BPA, zarówno z żywności, jak i ze źródeł poza żywnościowych (kurz, kosmetyki, papier termiczny), uwzględniające najbardziej wrażliwe grupy populacji, umożliwiły EFSA obniżenie TDI z 50 μg/kg mc/dzień do 4 μg/kg mc/dzień. EFSA w swojej naukowej opinii z 2015 roku podkreśla, że na podstawie aktualnych oszacowań całkowite narażenie niemowląt, dzieci i młodzieży na BPA ze źródeł żywieniowych i poza żywieniowych jest poniżej tymczasowego TDI, wynoszącego 4 μg/kg mc/dzień. W opinii tej EFSA podkreśliła, że BPA nie stwarza ryzyka dla zdrowia, przy oszacowanych poziomach narażenia, dla żadnej z grup populacji, włączając również nienarodzone dzieci i osoby starsze. EFSA wskazała jednak na potrzebę wyjaśnienia niektórych danych dotyczących narażenia i badań toksykologicznych.
