Yes meat glue is safe to eat and is not harmful to humans or animals.
The meat glue is not like the regular glue that we glue things together with but instead the meat glue is an enzyme that is added to the meat to help hold the meat together.
You cannot see or taste the meat glue in the meat.
People eat meats with meat glue all the time everyday and it does no harm.
It's not like the company mixes up regular glue that is not edible and mixes it with the meat to glue it together.
The meat glue is a food product that is safe to eat and consume.
Unless you grow your own animals and butcher your own animals for meat then you won't be able to get away from eating meat glue.
That is unless you stop eating meat.
