Always Buy Organic: milk. When you buy organic, it means the cows aren't treated with synthetic hormones or antibiotics, and they have spent at least one year in open fields grazing on grass. Organic milk lasts longer than conventional milk; it is sterilized at a higher temperature than regular milk -- 280 degrees vs. 145 degrees -- so organic milk's shelf life is up to two months. Less spoiled milk means you save money in the long run.
