Here we go again. Not so long ago governments worldwide banned the use of BPA in plastic containers. Studies showed the plastic chemical bisphenol A (BPA) was linked to some serious health problems including breast and prostate cancer, heart trouble, type II diabetes, autism, liver tumours, asthma, infertility and obesity. In response to the public's outcry, manufacturers removed the chemical from their products and replaced it with bisphenol S (BPS). Now it's been discovered that the replacement is as bad or worse than the original. This latest discovery, demonstrates yet again, the failure of a regulatory system that allows manufacturers to use chemicals that have never been properly tested to rule out potential health effects.
