I just read an editorial in the NY Times (instead of working, of course) regarding the spinach contamination. Apparently, the spinach industry is not to blame. The problem is with the beef and dairy farmers. They feed their cattle grain, which causes excess stomach acidity in the cattle, which the dangerous version of e.coli thrive in. The fecal matter contains the bacteria and it gets into the ground water, which irrigates the spinach and other vegetables. It said that 80% of all cattle are infected with the acid-loving bacterium. There are methods of containing it, but sometimes there are slip-ups. It said that experiments have proven that when cattle are fed hay, the e.coli go away in just a few days. It says the remedy is to stop feeding cattle grain.
Interesting, no? I'm not sure why the grain is preferred.
