Germany’s return of sacred Kogi masks to Colombia may have health risks

Wooden artefacts dating from 15th century and bought from indigenous people were treated with pesticides while in museum

Germany has returned two wooden masks of the indigenous Kogi community to Colombia but conceded that wearing the sacred artefacts in ceremonies may come with a health risk because they were treated with toxic pesticides during their time in German museums.

The masks, which date back to the mid-15th century and have been held in ethnological collections in Berlin for over a century, were handed over to Colombia's president, Gustavo Petro, by his German counterpart Frank-Walter Steinmeier at a ceremony in Berlin on Friday.
