It looks like flukes to me.
Flukes are meaty.
They start out as round balls and then they range in colors of pink, red, maroon and black. These range in youngest to oldest,black being the older fluke.
Ask Humaworm and others that have flukes.
Rarely does a fluke come out looking like the typical pictures when one is not taking medication for these.
There are certain drugs ( animal drugs) that do kill them and they can come out whole.
