Researchers at the Centers for Disease Control and Prevention (CDC) are using DNA technology to try and prevent future E. coli outbreaks.

 

The method is called genome sequencing and it could eliminate the guessing game when it comes to finding the source of E. coli outbreaks. With it, scientists can determine the exact food and location in which the contaminated produce originated.

At least one person has died and more than 100 people have fallen ill from E. coli following a recent outbreak in connection with romaine lettuce from Arizona.

 

"Do not eat or buy romaine lettuce unless you can confirm it is not from the Yuma, Arizona growing region," says a statement from the Centers for Disease Control and Prevention (CDC). "This includes any pre-packaged salads or salad mixes.”

 

Dr. Patricia Griffin, chief of the enteric diseases epidemiology branch at the CDC, explains how the recent outbreak happened and what consumers should be aware of when buying produce.
