I mean yeah, I can buy “agricultural pollution” as a potentially serious problem, what with the livestock excrement and chemical fertilizers and all that, which could run off into waterways. It might be reasonable to ask farmers to take some sort of remediation measures if those are shown to be harming other people’s property.

But MILK?

Besides, considering that (unlike, say, manure, where you’d be a lot more likely to find e coli in large concentrations) the whole purpose of a dairy farm is to _collect_ the milk and then sell it, how much are they really going to be spilling into the environment anyway? Sure, there’s some spillage, but it’s got to be a pretty small amount, relatively speaking.
