Non-Muslim driver transporting halaal meat to the butcher shop for slicing

Umar slaughtered a sheep at home. He sends the meat with his non-Muslim driver to a Muslim butcher for slicing. The Muslim butcher slices the meat and sends it back to Umar with the non-Muslim driver. Hence, there was no Muslim supervising the meat during the travelling periods to and from the Muslim butchery.

1. Is it permissible to eat this meat?

2. Is this meat Halal?

3. If not, please suggest how this meat should be disposed of.
