Couldn’t open the link but is it based on American systems? They farm dairy very differently to the UK (and europe) and use hormones to produce milk rather than the cow having a calf. Their way is illegal here so no hormones in British (and European) dairy products.
Our milk is sampled daily, if there is anything in there that shouldn’t be it all goes down the drain.
Yes an American who runs the website as a Charity, albeit staffed with a large number of well paid staff, and through the website promotes his books.
Not convinced OP but do agree with the old adages (although not often good at living by them!) – we are what we eat and everything in moderation.
