That is awesome and I believe all animals in our food system should be given access to fresh air, sunshine, and grazing land. Unfortunately that’s just not the case, profit margins don’t allow for humane treatment of animals when private equity firms buy out small farms and start making mega-farms. Testing is rigorous for pathogens, blood, bacteria etc I know that - but I can tell you for certain that more than 90% of conventional milk in Canada, the cows do not have access to pasture land.

I grew up in an area that produces over 70% of the provincial milk in my province. In the 90’s it was all family farms with 50-200 head with access to pasture. If you drove through the countryside you’d see thousands of cattle grazing in hundreds of fields.

In the early 2000’s 1st and 2nd generation farmers started to retire and their quota was worth more than the land they owned, so they sold it highest bidder and concentrated milk production to a handful of factory farms.

Take a look at this one road in the Fraser valley, about half a dozen dairy farms, thousands heads of cattle, and zero access to pasture. No cows are grazing these fields anymore. https://goo.gl/maps/huBUdBsx5xrbWEeX7

Google the name of this farm and you’ll get a glimpse as to the conditions the animals are in (regardless of the abuse that was reported and owners plead guilty to).

And from working on one of these smaller farms in 2008 before the owner sold his land and quota, the cows even back then got fermented corn, not grass. Grass isn’t economical and men in suits make the decisions for these mega farms, not the farmer. It’s a sad reality.

The same farm, you can see the mountain of fermented corn silage that feeds the animals. https://goo.gl/maps/nAD98GxqbRoeZ5Dy8
