The sink is pretty thoroughly grounded in most residences.

=====

No ground on my sink via the ABS drain pipes or the PEX supply tubes
either.

Then it's grounded though the water in the pipes. And the ground wire
to the disposal.

To get a shock you need a voltage _difference_. Not gonna happen with a
garbage disposal full of water.

==================
Geeeez! I hope you don't actually believe that one.
Water is not a good or reliable ground. Pure water is a complete insulator.

Not acceptable, not safe and will not pass the safety requirement in any
code (use of water for ground). Copper pipes can make good conductors but
not to be relied on in most cases.

If the water is a good enough conductor for you to get injured through
it then it's good enough to keep the sink and disposal at ground
potential.

This isn't the radio in the bathtub scenario. The current source is
buried deep in the guts of the disposal and the shortest path is going
to be inside the disposal, not through the water in the sink that is
likely to shock you.

But you go on being afraid of garbage disposals. The rest of us have
lives.
