The Siskiyou Daily News reports that in light of food poisoning outbreaks involving spinach and lettuce, the government and the produce industry are scrambling to make leafy greens safer before the spring planting season.

New guidelines from the industry are due in April on how to prevent contamination throughout the food chain, from before greens are planted until they reach the dinner table.

Members of Congress are asking federal agencies to report on what went wrong and how to fix the problem. Some lawmakers want to replace the patchwork system of federal food regulation with a single agency in charge of what people eat.

States are active, too. In California, where most of the nation’s green leafy vegetables are grown, farmers are poised to approve new labeling by March for farms that follow stricter practices for raising greens.
