Should the government improve food safety regulations for leafy greens?

At industry request, as a result of the E. coli outbreak in leafy greens last fall, the Agricultural Marketing Service of the USDA announced Thursday its intention to create future regulation of leafy greens to supplement the FDA's food safety regulations. It is unclear what the actual nature of this regulation would be, but the ANPR (advanced notice of proposed rule) describes:

the establishment of a marketing program to address the handling of fresh and freshcut leafy green vegetables. The program would allow packers, processors, shippers, and marketers (collectively referred to as handlers) to maintain the quality of their products by reducing the risk of pathogenic contamination during the production and handling of leafy greens.

and is soliciting public comments about whether they should create such a program and if so, what the implementation would look like, by December 3, 2007. Comments can be submitted to http://www.regulations.gov.
