I've received many emails on this issue as well as a comment from Erikka. The USDA is considering a proposal to regulate the growing of leafy greens. The regulations make no sense and will harm small, sustainable farmers. To read more information about this proposal, go here: http://www.earthtimes.org/articles/show/news_press_release,229965.shtml
The USDA has open comments right now through December 3 on this proposal. You can go here: http://www.regulations.gov/fdmspublic/component/main to make your comments. The comments can be made online, it is quick and easy to do. Click on the 3rd docket from the top.
If anyone knows anything about the top one concerning dairy products I'd be interested in hearing about it.
