The Court of Justice of the European Union has ruled to annul the European Commission’s 2019 classification of titanium dioxide, which is also known as E171 and is used to add white color to foods, as a carcinogen.

As of summer 2022, it will be illegal to use titanium dioxide in food products made in Europe.

An expert panel recently concluded that food coloring E171 (titanium dioxide) "can no longer be considered safe as a food additive," and as a result, the European Food Safety Authority (EFSA) has reclassified it.
