Intake of bisphenol A from canned beverages and foods on the Belgian market

Abstract

Bisphenol A (BPA), a contaminant which may be present in the coating of cans, was determined in 45 canned beverages and 21 canned food items from the Belgian market. Beverages had an average BPA concentration of 1.0 ng/ml, while canned foods had a higher average concentration of 40.3 ng/g. The amount of BPA present in food items was dependent on the type of can and sterilisation conditions rather than the type of food. For example, BPA was not detected in non-canned beverages (<0.02 ng/ml), while non-canned food items had a very low average concentration of 0.46 ng/g. Using detailed information from the Belgian food consumption survey, the BPA intake of adults through canned foods and beverages was estimated to be 1.05 µg/day or 0.015 µg/kg body weight/day (assuming an average adult weight of 70 kg). Intake assessments, based on urinary metabolite concentrations from the literature, resulted in slightly higher BPA intakes (range 0.028-0.059 µg/kg body weight/day). This suggests that sources other than canned foods and beverages contribute to BPA exposure in humans.

Exposure to Bisphenol A From Drinking Canned Beverages Increases Blood Pressure

“…23 Several previous studies have reported that BPA in the inner coating of cans may leach into the food based on measurements of BPA concentrations in various canned products. [24][25][26][27][28][29] BPA concentrations in the canned beverage in the present study were comparable with the results of previous studies. For instance, Lim et al 26 reported that mean BPA concentrations in canned beverages were 8.30 μg/kg, with the range being nondetectable to 14.26 μg/kg.…”

Monitoring of bisphenols in canned tuna from Italian markets

“…Due to an incomplete polymerization process, residues of bisphenol monomers in PC food containers or epoxy resin coatings can migrate into foods, especially oily food, during storage and processing at high temperatures (Brede et al, 2002;Cao et al, 2011;Geens et al, 2010;Grumetto et al, 2008;EFSA, 2006;Noonan et al, 2011;Rauter et al, 1999;Simoneau et al, 1999;Sungur et al, 2014;Theobald et al, 2000). Furthermore, migration from parts of facilities and/or utensils routinely employed during the food production process may occur under certain conditions (Casajuana andLacorte, 2003, 2004;Goodson et al, 2004;Grumetto et al, 2013;Guart et al, 2011).…”

Biomonitoring of bisphenol A in hair of Greek population

“…Its release in the food chain is related mainly by sterilization process (temperature and time) and the amount of coating. As it is mentioned, BPA migrates from the coating of the can into the content mostly during the sterilization process (Howdeshell et al, 2003;Takao et al, 2002;Geens et al, 2010;Munguıa-Lopez et al, 2005). Duration of can storage, elevated temperatures during storage or damage of the can do not affect the levels of BPA in the food (Goodson et al, 2004).…”

“…due to the low water solubility of BPA, canned food with high fat content has higher detected levels of BPA in the solid portion compared to the liquid portion (Geens et al, 2010).…”
