“Cremation essentially mineralizes the human body and produces ashes that are rich in carbon and not much of a health concern,” Halden said.
So, the ash isn’t toxic, and it’s not like it would carry any diseases.
“Proper cremation will remove all infectious properties of the remains, thus allowing people to take the ashes home and store them in living spaces,” he added.
That doesn’t mean there are no possible dangers.
“The one potential concern worthy of consideration would be heavy metals, as can be found particularly in tooth fillings,” he said.
