But vats can still support bacteria colonies, just like cows can.
Ideally, they'd be sterilized between batches, in a way that left no residue on the product. In practice, though, I wonder if they won't need to use antibiotics (or something like them) in order to ensure a safe product.
The advantage will be that all those antibiotics don't run off into the soil... except for the plant's wastewater. Still, it ought to be more localized than the current practice.
