This week, we welcomed back Aaron Gross, PhD, director of USD's Center for Food Systems Transformation. He explained to us how food -- vegetables and meat alike -- make it from farms to our plates, and how they can pick up bacteria and food-borne illnesses along the way. He talks about how the systems in place make it difficult for consumers to make informed decisions, what they can do as individuals, and what everyone can do to try to improve conditions and remove some of the ambiguity around our food.
