Why?
Because on the hands, there can be bacteria, and it can form actually biofilms on the hands and in the environment.
And that means it's harder to remove than just a simple little wash off.
The same can be true on the outside of these other, of the teats that the cow has.
They can actually be permanent bacteria living on the outside of it that are very hard to remove.
And remember, this is a sensitive area for the cow too, so you can't spend five minutes like the doctor scrubbing.
I'll give you just an example.
One of my colleagues here at the University of Wisconsin did a study of a farm here in Wisconsin.
And she literally went out and sampled poop from these animals and cows.
90% of the animals were carrying listeria monocytogenes.
I would say, you know, if you look at the percentage of the different pathogens, sometimes you see 5% of them are contaminated with Listeria, 5% are contaminated, roughly.
I'm giving broad ranges with Campylobacter, E. coli, etc.
Sometimes it's as high as 20 to 30% have one pathogen present in the bulk tank.
children end up being the most largest percentage of hospitalizations for raw milk outbreaks.
They don't have a choice.
They don't know anything.
They've been mom and dad feeding it to their kids.
Those are the ones that I get most concerned about.
And depending on which study you take, sometimes it's like a quarter or more, or sometimes under the age of three and five years old.
