This popular Taiwanese beverage might be both fun and tasty, but German health authorities and researchers are adding more health reasons that might just bust your bubble tea bubble.


According to researchers from the University Hospital Aachen, the tapioca balls known as 'pearls' which are commonly added in the drink contain traces of polychlorinated biphenyls (PCBs) such as styrene, acetophenone, and brominated substances.

PCBs have been shown to cause cancer, as well as a variety of other adverse health effects on the immune system, reproductive system, nervous system and endocrine system.

The study comes on the heels of another public health warning from the country’s German Federal Institute for Risk Assessment, which warned that the tapioca balls could also present a choking risk to children.
