According to sources at the CDC and other outlets, the origins of swine flu are at a hog farm in Mexico where over 950,000 were raised for food in 2008. The farm, Granjas Carroll is a subsidiary of Smithfield Foods.
News about th eswine flu outbreak in Mexico that crossed into the US had confirmed cases in California and Texas with 68 fatalities in Mexico.
It is believed that contamination from pig breeding at the farms polluted the local water bodies that led to the idsease outbreak, although Granjas Carroll claims that the outbreak was the 'flu.'
The question on agricultural list serves is, can such a thing happen in small scale farming?
