Thanks for the example of raw milk - a good one. Since I spent part of my life milking cows for a living and part of it as a man from the Min of Ag, you might have thought I'd have recalled it
The .gov page that explains what raw milk is also goes to some length to imply very heavily that it's nasty, dangerous stuff and you're a mug if you drink it (I've drunk plenty, of course - does that explain the poor memory?)
Some people seek out raw milk, but it's very much a minority view, and "raw" meat and, especially, chicken have very negative associations for a lot of people. When pasteurisation was first introduced there was a lot of suspicion about it, and a lot of marketing money was spent to change perception and give the word a positive spin. Inevitably, that had the effect of casting "raw" as the pantomime villain
