Good point. I’m unsure what the best practise in editing previous comments is—I don’t want to change it so much that the subsequent comments don’t make sense to another reader. Clarified now by leaving in the original number that fits with the reasoning around it while keeping the correction in brackets.
I think it would also be worth keeping in mind how hard it is to make progress on each front. Given that there seems to be widespread non-therapeutic use of antibiotics for farmed animals, and that (I believe) most people have accepted that antibiotics should be used sparingly, I would be surprised if there were no “low-hanging fruits” there. This is not meant as a complete solution, but rather is an attempt to identify our “next best move”. I would believe that cheap in-farm diagnostic tools should now be within reach as well, or already existing.
Separately from this, I admit being confused about the nature of the question regarding the importance of dealing with over-use of antibiotics in farmed animals. My understanding is that we know that inter-species and horizontal gene transfers can occur, so is the question about knowing how much time it takes? I just don’t have a clear model of how I’m supposed to think about it. Should I think that we are in a sort of “race against bacteria” to innovate faster than they evolve? Why would a delay in transfer to humans be a crucial consideration? Is it that antibiotic innovation is mostly focused on humans? Is there such a thing as a human-taylored antibiotic vs. farmed animal antibiotic? I suppose not? I cannot wrap my head around the idea that this delay in transmission to humans is important. So I guess I’m not thinking about it right?
[Added later:] Maybe the point is that if some very resistant strain emerges in a farmed animal species, we have time to develop a counter-measure before it jumps to humans?
