Officials from the CDC and USDA will likely arrive in Mexico soon to help investigate the deadly new influenza virus that managed to jump from pigs to people in a previously unseen mutated form that can readily spread among humans.
One of the first things they will want to look at are the hundreds of industrial-scale hog facilities that have sprung up around Mexico in recent years, and the thousands of people employed inside the crowded, pathogen-filled confinement buildings and processing plants.
Industry calls these massive compounds "confined animal feeding operations," or CAFOs (KAY-fohs), though most people know them simply as "factory farms." You have seen them before while flying: Long white buildings lined up in tightly packed rows of three, four or more. Within each confinement, thousands of pigs are restricted to indoor pens and grain-fed for market, while breeding sows are kept in small metal crates where they spend most of their lives pregnant or nursing piglets.
In the last several years, U.S. hog conglomerates have opened giant swine CAFOs south of the border, including dozens around Mexico City in the neighboring states of Mexico and Puebla. Smithfield Foods also reportedly operates a huge swine facility in the State of Veracruz. Many of these CAFOs raise tens of thousands of pigs at a time. Cheaper labor costs and a desire to enter the Latin American market are drawing more industrialized agriculture to Mexico all the time, wiping out smaller, traditional farms, which now account for only a small portion of swine production in Mexico.
