i think one of the most tramatic things that i've seen is that people have been bitten by rats. In many other parts of the world, it's much worse where you can see babies with their noses bitten off entirely. We know rats are involved in salmonella transmission, but to what extent? It's a question of how much do we want to invest and try to understand what the real impact is in food production particularly. I think we massively underestimate the impact, but no one's looking.
