Bisphenol A (BPA) is used in a wide variety of products and objects for consumers use (digital media such as CD’s and DVD’s, sport equipment, food and beverage containers, medical equipment). For humans, the main route of exposure to BPA is food. Based on previous estimates, almost 20% of the dietary exposure to BPA in the French population would be from food of animal origin. However, due to the use of composite samples, the source of the contamination had not been identified. Therefore, 322 individual samples of non-canned foods of animal origin were collected with the objectives of first updating the estimation of the exposure of the French population and second identifying the source of contamination of these foodstuffs using a specific anal. method. Compared to previous estimates in France, a decline in the contamination of the samples was observed, in particular with regard to meat. The estimated mean dietary exposures ranged from 0.048 to 0.050 μg (kg bw)-1 d-1 for 3-17 yr children and adolescents, from 0.034 to 0.035 μg (kg bw)-1 d-1 for adults and from 0.047 to 0.049 μg (kg bw)-1 d-1 for pregnant women. The contribution of meat to total dietary exposure of pregnant women, adults and children was up to three times lower than the previous estimates Despite this downward trend in contamination, the toxicol. values were observed to have been exceeded for the population of pregnant women. With the aim of acquiring more knowledge about the origin the potential source(s) of contamination of non-canned foods of animal origin, a specific anal. method was developed to directly identify and quantify the presence of conjugated BPA (BPA-monoglucuronide, BPA-diglucuronide and sulfate forms) in 50 samples. No conjugated forms of BPAs were detected in the analyzed samples, indicating clearly that BPA content in animal food was not due to metabolism but arise post mortem in food. This contamination may occur during food production However, despite extensive sampling performed in several different shops (butcheries, supermarkets …. ) and in different conditions (fresh, prepared, frozen …), the source(s) of the contamination could not be specifically identified.
