Now, I don't drink milk or consume dairy due to me being Paleo, but my wife and children do (they are Primal), hence why I found the following extremely interesting as well as worrysome when I was unable to locate where any of my fridge's dairy came from.
Go to the following site (http://whereismymilkfrom.com/) and follow the directions on how to enter in the dairy codes to see where, exactly, the products in your home came from.
Here's a list of all the possible products that you can use the site to find out where they came from:
