Knowing how chemicals and carbon compounds are recycled in Earth’s ecosystem and taking into account factory farming, I would wager the line between poop to serving of hot steak is much a much less connected line on a ship that turns matter into its constituent energy patterns.
Meanwhile on Earth we routinely have meat recalls because of e-coli contamination. Which is poop. As well as what we use to fertilize our root vegetables. Everyone is eating poop to some degree, it just becomes a problem when enough of it is in one spot to become contamination.
