Fast forward to the modern era: In 5722/1962, workers digging a foundation for the zoo’s new barn discovered a skeleton and a casket. They reburied the casket in situ and poured the foundation right on top. During 5758/1998, workers constructing a parking lot in the area discovered 81 skeletons and an iron casket containing a cadaver. There are at least nineteen more reports of human bones found in the disused cemetery’s location. Thus, the shaylah is whether a Kohen may walk through the streets and businesses of this old-time burial ground.

“I am scheduled to have a dental implant placed in my mouth.
My dentist told me that the procedure may require the insertion of cadaver bone
around the implant. Since I am a cohen, I
immediately realized that I may have a serious halacha problem on my hands, or
more accurately, in his hands and my mouth. May I have these products inserted?
May I even go into the dentist’s office knowing he has these remains (parts of
a corpse) on hand? Maybe I cannot even enter the building?”
