BPS has become popular as a replacement for bisphenol A (BPA), which is classified as a substance of very high concern (SVHC). However, the use of BPS for printing on food packaging is not without problems according to the two studies, as this substance can also have adverse health effects such as impairment of the heart function and fertility.
Exceeds EU limit values
Canadian researchers examined 140 packaging samples and measured high levels of BPS and other colour developers that had migrated into food from plastic films, labels and styrofoam packaging. BPS was detected in 46 of the samples, but no BPA.
Canada does not regulate BPS, but the migration levels found exceeded the limits set for BPS in food packaging in the EU.
The Turkish study investigated if BPS and other bisphenols (BPA, BPF, BPB) could migrate from the inside of cans to their content of convenience foods, cooking oils, soft drinks, etc. A total of 79 cans were examined and excessive levels of BPS were measured in six samples and of BPA in 57% of the samples.
In the EU, a consultation procedure is currently taking place regarding restriction of the use of bisphenols.
