I just read an interesting take on how the Swine Flu may have started, it seems there's a raging debate going on over at the Society for Environmental Journalists listserv.

"As of the moment,  about two weeks into formal medical forensic investigation,  no one knows just what the source of the mutant H1N1 virus first discovered in the Vera Cruz region of Mexico might have been.

Much attention has been given to the case of five-year-old Edgar Hernandez,  of the La Gloria hamlet in Perote,  near the Granjas Carroll factory pig farm.  Hernandez-who survived-is the earliest victim of the mutant H1N1 virus from whom a sample was preserved.  La Gloria residents blamed Granjas Carroll for an outbreak of illness in February and March 2009.  Officially attributed to biting flies,  the illness produced flu-like symptoms.

Granjas Carroll is half-owned by Smithfield,  the world's largest factory pig producer,  involved in pollution incidents at multiple sites on several continents. "
