5 dead, nearly 200 sickened in U.S. romaine lettuce outbreak
Total number of illnesses rises to 197 in 35 states
Four more deaths in the U.S. have been linked to a food poisoning outbreak blamed on tainted lettuce, bringing the total to five.
Health officials have tied the E. coli outbreak to romaine lettuce grown in Yuma, Arizona. The growing season there ended six weeks ago, and it's unlikely any tainted lettuce is still in stores or people's homes, given its short shelf life. But there can be a lag in reporting, and reports of illnesses have continued to come in.
In an update Friday on the largest E. coli outbreak in a decade in the U.S., health officials said 25 more cases have been added, raising the total number of illnesses to 197 in 35 states. At least 89 people were hospitalized.
- SECOND OPINION | As officials give all-clear on romaine E. coli outbreak, contamination remains a mystery
Previously one death had been reported, in California. On Friday, health officials said they had learned of four more — one in Arkansas, one in New York, and two in Minnesota.
The first illnesses occurred in March, and the most recent began on May 12, according to the U.S. Centers for Disease Control and Prevention.
Many of the new cases were people who became ill two to three weeks ago, when contaminated lettuce was still being sold. Some said they did not eat romaine lettuce but were in close contact with someone who got sick after eating it.
The Public Health Agency of Canada says six people in four provinces became infected with bacteria that is genetically similar to the one reported in the U.S. E.coli outbreak.
Most E. coli bacteria are not harmful, but some produce toxins that can cause severe illness. People who get sick from toxin-producing strains such E. coli O157:H7 come down with symptoms about three to four days after swallowing the germ, with many suffering bloody diarrhea, severe stomach cramps and vomiting.
Most people recover within a week, but some illnesses can last longer and be more severe.
