Do you ever wonder how your gallon of milk got to the grocery store? Milk goes through several steps before you can find it on the shelf. It might surprise you that many dairy products start out not far from home. Dairies are in all 50 states so it makes it easier to have locally produced dairy products in your grocery. Even those without a “local” label often start within driving distance of your kitchen. For example, when you pick up a gallon of milk from your local Hy-Vee, it’s likely coming from within a 60-mile radius of Sioux Falls. Let’s take a look into the journey your gallon of milk takes to get to your local grocery.
Before your gallon of milk can be enjoyed, dairy cows must produce the milk. Most dairy cows are milked twice a day. The milk is then cooled in a large storage tank on the farm and, within 24 hours, it is taken to a local processing plant in an insulated truck that keeps it cold. For example, a dairy farm in Garretson may drive their milk 55 miles to a processing facility in Brookings.
After a short road trip, the milk arrives at the local processing plant and is tested for safety. Dairy farmers and milk processing plants want to ensure the milk they deliver and use is safe. Next, the milk goes through a process called pasteurization. Pasteurization kills pathogens with heat and is just another step to ensure the milk is safe for consumption. After pasteurization, milk is packaged and sent 60 miles to grocery stores in Sioux Falls and beyond.
Isn’t it interesting to know that the entire farm-to-shelf trip for a gallon of milk can take only two days and 115 miles? The next time you’re at the store, remember that cows right down the road likely made that milk that is in your shopping cart. Local farmers and processors work to bring that gallon of milk from the farm to your home quickly and safely every day.
