This procedure is carried out conscientiously. Every surface which the milk touches is left in a sanitized condition. Every farm and its herd are government inspected. Failure to maintain sanitation and good animal health would mean the milk could not be shipped from the farm in question. Each farmer ships his milk to a dairy processing plant.
Milk is picked up by an insulated stainless steel bulk tank milk truck.
It makes regular calls at farms on its route on a very strict schedule to ensure rapid transfer of milk to the plant. Each truck driver is a licensed milk grader. He takes samples of milk into sterilized bottles which are stored in the truck for delivery to the testing laboratory. From the dipstick reading, he records the quantity of milk in the farm storage tank. A vacuum hose is attached from the truck to the storage tank.
