In an article published on January 9, 2017 the Danish Consumer Council THINK Chemicals informs about a testing campaign analyzing the metal packaging of 14 soda drinks for different bisphenols. The coating lacquers on the inside of the soda cans were tested for bisphenol A (BPA, CAS 80-05-7), bisphenol F (BPF, CAS 620-92-8), bisphenol S (BPS, CAS 80-09-1), and bisphenol A diglycidyl ether (BADGE, CAS 1675-54-3). Seven of the 14 can coatings contained BPA and one contained BPF. BADGE was found in the coating of all but one of the cans, whereas BPS was not found in any of the cans. The content of BPA in the seven cans ranged from 1.7 to 3.5 µg per can. The content of BPF in the one can was 1.6 µg per can. The content of the bisphenols in the actual soda drinks was not measured. However, the Consumer Council notes that “earlier research has shown that bisphenol A can migrate from packaging to food and beverages, and that the substance can be found in canned beverages.”
“The content of bisphenol A and BADGE in the cans was low in comparison with the EU limit values, which however are about to be revised,” the Consumer Council further states. BPA is an endocrine disrupting chemical (EDC). Less is known about BPF and BADGE, but both are suspected EDCs, the Consumer Council explains.
At the bottom of its article, the Consumer Council provides comments from some of the manufacturers of the affected soda cans.
