The source of the outbreak is traced to fresh, bagged spinach from the California-based Natural Selection Foods company, which issues a voluntary recall of its spinach products.

OK... OSHA and USDA notwithstanding... organic in California is moot. Thousand acre farms are not what the average person envisions, but that is what they have. How else to provide relatively "cheap" produce to stores across the country.

And while highly mechanized, they still involve lots of manual labor... and that is the most likely source of the contamination... not raw manure, except what traces linger on poorly washed hands of poorly paid labor. Plenty of weak links in the chain here... and the public is too divorced from agriculture to have a better understanding of what goes on.
