Holy Grail or afterthought?

How important is a seal or label demonstrating to consumers that California leafy greens were grown according to Good Agricultural Practices? That's a practical consideration now. As this story notes, the California leafy greens marketing agreement board is considering the use of a seal.
From the story:

"There is a plan at some point to use a seal that would alert consumers, so that they'd know the produce they're purchasing has been handled properly," says a spokesman for the California Department of Food and Agriculture.


TK: How brand marketers choose to display the seal on bags of spinach and other leafy greens will be revealing. One would think the board will likely put some parameters in place regarding the size of the seal on consumer bags, and its use may be optional. I think the use of the seal is a good idea and will be important to consumers, at least in the short term.
