They say it cannot be spread through food- well, this is nuanced, I thought the initial case came from someone getting, cooking, and eating a fruit bat? Maybe you can’t get it by eating cooked food, but you can get it by preparing contaminated food.
I don’t think they have proven whether or not you can get it by eating food or drinking water.
I think there is a lot we don't know about how it spreads, including what animals can carry it around and spread it, whether it can survive in sewers, etc. The obvious routes of infection are likely not to be the only ones.
