US health organizations are asking public to avoid eating fresh spinach¹
U.S. health officials are still trying to pinpoint² the source of an E. coli outbreak that has caused at least one death and sickened scores of others across the country. 

U.S. health officials normally tell Americans to eat more leafy green vegetables.  Now, they are being warned to stay away from fresh spinach.  The reason: at least some spinach grown in California and shipped around the country has been tainted³ with a particularly virulent⁴ strain of E.coli bacteria.

 
Gwyn Wellborn
Gwyn Wellborn spent 13 days in the hospital after eating a spinach salad. "I was scared,” she says. “They weren't sure if I'd make it another couple hours or another day."

Wellborn is 27 years old, but an elderly woman in the Midwestern state of Wisconsin died from E.coli.  Wisconsin Health Commissioner⁵ Bevan Baker⁶ said, "The elderly and the very young are those we are concerned about."

 
Lab testing for E.coli O157:H7
That's because this particular strain, E.coli O157:H7, is particularly virulent.  It can cause bloody⁷ diarrhea, severe abdominal⁸ cramps⁹ and hemolytic uremic syndrome¹⁰. That's a disease that causes kidney failure.  In young children, most cases of hemolyic uremic syndrome are caused by this particular strain of E. coli. And those infected can pass it on to others. 

Dr. Roger Clemens from the University of Southern California School of Pharmacy¹¹ says,

"Most organisms such as E.coli you have to consume large quantities to make you sick, what sets this apart is you only have to consume small quantities to make you sick."

 
Caroline Smith DeWaal
E.coli is found in the intestines¹² of healthy animals. Caroline Smith DeWaal with the Center for Science in the Public Interest explains. "The bacteria lives in the guts¹³ of cows and other bovine¹⁴ and it would get on to the fresh spinach through manure¹⁵, through contaminated irrigation water."

And it could have contaminated the spinach through other means. Dr. Robert Brackett and others at the U.S. Food and Drug Administration are trying to pinpoint where the contamination started and how it spread.

 
Dr. Robert Brackett
"It could be contaminated water, it could be wildlife, it could be the workers. When you get to the plant it could again be workers in the plant."

The spinach is chopped and washed and mixed together, then shipped throughout the United States.  Health officials are telling Americans, for the time being, not to eat raw spinach and to practice good hygiene¹⁶ with plenty of handwashing.
