I don't think so. I remember that we bought milk directly from the farm as a kid (Germany, so experiences may vary), but it always got collected in a big container that automatically pasteurized it during storage. Every farm had those, so they couldn't have been that expensive.
Don't rely on one source, mix it up.
For me, the Guardian for international news, the Economist for more economic topics and analysis, Süddeutsche Zeitung for a German view and BR24 for local news and to get enraged over idiot comments.
I have it as: "cool idea, i'll let you get away with it once. Start abusing it and all the NPCs start using it." works pretty good.
