make sure it is clean and safe.

Fresh from the
dairy case. Look
at all your
choices!
From farm to table, milk never
touches human hands. That’s to make
sure it stays clean and pure.
Check and re-check.
From the processing
plant, it's on the road
again. Refrigerated
delivery trucks distribute
dairy products to
grocery stores.
