Good Luck Brother!! The best advice I can provide is to ignore the internal organs. Just about everything everywhere has been contaminated by something in someway.

When you are hungry, that will be one of the last things that you will worry about.

When you are sufficiently hungry, rats look delicious and even cockroaches start looking good.
