I've met a number of cows too(or bullocks rather) but to quote a previous employer " They all look the same with their jackets off "
I'm sorry, but I have to disagree with 'the farmers point of view'
What does the farmer actually know ? Sure you can say its microbiome of cows(fungi etc) but this is just a word and thats pretty much all farmers can quote of it. They might have a basic understanding, but not an in depth understanding.
If the farmer has a phd in microbiology, then his point of view holds water so to speak, otherwise he's just quoting words he has no real understanding of.
As a butcher i had a basic understanding of cross contamination, or of some diseases that affect animals, but no more than your common mans understanding.
That is until i took a course in meat inspection, of 2 years run by the school of veterinary medicine. That gave me an understanding of the lymphatic system, or how contamination works, of how bacteria is spread and the danger it poses. But even then it is only a 2 year basic course that would qualify me as a meat inspector, but in depth, you'd need to do a 4 or 6 year in depth course with academic qualifications.
So I could examine the lymph nodes of an animal post slaughter(or any other obvious signs- build up of lymph fluid,, to see if any changes were present, and condemn it or set it aside for further study and keep it out the food chain. But the actual understanding of the mechanics of it would be well above my pay grade.
People on facebook run off to wiki to get a few buzz words they throw into the conversation, but thats as far as their understanding of the subject goes. And in fact are more a hindrance than a help, and i'd go so far as they are a danger to public health
And as to the daily mail article, the end paragraph pretty much sums it all up in context of how the daily mail frames its articles.
Theyre using the word 'contaminate' when it is really just an additive, like the many others in other products. There are preservatives on many foods - are they contaminates ?
"Questionably linked to cancer" more fear mongering, again the usual tabloid board of fare. Questionably is a term used when something is not entirely accurate or true. So yes there might be a cancer issue, but in 1:100,000,000 cases, or such that it is negligible as a real risk.
