E.coli 0157 -
In 1996, an outbreak of E.coli 0157 bacterial disease in Scotland involved the largest recorded number of infected adults in whom the early digestive-tract symptoms progressed to life-threatening kidney disease. Twenty-eight of them died.
That same year, 7,966 individuals were diagnosed with E.coli 0157 infection in a single outbreak in Japan.
Because the guts of healthy cattle are a reservoir for E.coli 0157, the animals, their manure, and the land they've grazed, are potential sources of the infection. The bacteria can also make their way from fields into the water supply.
The Scottish E.coli 0157 outbreak was caused by contaminated raw meat stored next to cooked meat. The Japanese outbreak was caused by radish sprouts contaminated by infected water.
Organic foods have always been seen as an arch-enemy by biotech proponents. In a desperate attempt to trash organics, they've even been blamed for deadly infections of E.coli 0157 bacteria.
