The wording of “organic” can be confusing, just like the terms, “fat-free, low-fat, reduced-fat. So it’s important to understand the different labels and what they mean.
I use to think “Organic USDA” certified meant that the product really was organic through and through, and then I read in some reports that some items that had that certification were not in fact pure organic. This labeling explains that dilemma.
