Three more states - Iowa, Nebraska, and OR - have also reported cases, the CDC said.
The Center for Disease Control said 23 more cases have been reported in 13 states.
Romaine lettuce of all varieties from the Yuma, Arizona, region has been blamed as the source of this outbreak. The most recent illnesses reported to CDC started when romaine lettuce from the Yuma growing region was likely still available in stores, restaurants, and in peoples' homes.
Since 1995, there have been 78 outbreaks linked to leafy greens, he said.
Since product labels often come without the identification of the growing region, we suggest you pass on romaine lettuce if you are uncertain about where it was grown.
The person could have consumed the romaine lettuce at home, at a local restaurant or somewhere outside the area, Rooney said.
This nasty outbreak has infected 172 people across 32 states, according to the CDC.
"CDC is updating its advice to consumers".
Health officials say there is a lag time of two to three weeks between when someone falls ill and when it's reported to the CDC. One death has been reported. Sixty-five percent of ill people are female.
At least 75 people have been hospitalized, including 20 with kidney failure.
The CDC said that consumers should speak with their doctor if they have symptoms of an E. coli infection, which include diarrhea, severe stomach cramps and vomiting.
