So Old I'm Losing Radiation Signs
It is possible that instead they only harvest organs off of normal people, and they're somehow producing serum from the captured ghouls for sale.
Making ghoul juice with the prisoners is what I thought they were doing, but they never actually say that or acknowledge anything about it. The whole organ harvesting operation also doesn't make sense, because who is buying all of these organs? How are they being transported without spoiling, and where is the market for them? Filly? Are they floating organs on barges up to San Francisco? Do people have to come to the Super Duper Mart and let Snip Snip do the transplants?
