(NBCNC) — A new report from the Centers for Disease Control and Prevention reveals leafy greens have become a major source of E. coli outbreaks in recent years.

Researchers identified 40 outbreaks of E. coli infection linked to leafy greens between 2009 and 2018 in the U.S. and Canada.


More than 1,200 people became sick and there were eight deaths from contaminated greens.

More than half of the outbreaks were linked to romaine lettuce and the majority occurred in the fall.

Many times, the source of contamination was never found because greens grown on different farms are often mixed together.

Leafy greens are the second most common source of foodborne E. coli outbreaks after ground beef.
