CDC issues new romaine lettuce warning

Officials said a water reservoir at Adams Brothers Farms in Santa Barbara County tested positive for the bacterial strain and the owners are cooperating with USA officials.

The U.S. government also narrowed the source of the outbreak to three California counties: Santa Barbara, Monterey and San Benito.

A week later, on November 23, the FDA worked with the Centers for Disease Control and Prevention, as well as the California Department of Public Health and the California Department of Food and Agriculture, to trace back the strain, E. coli O157:H7, to contaminated romaine lettuce.

The farm did not immediately respond to a request for comment. No deaths linked to the outbreak has been reported. There have been 23 hospitalizations and two cases of hemolytic uremic syndrome, a type of kidney failure.

In Canada, there are 27 illnesses under investigation, according to the Public Health Agency, which continues to advise residents in Ontario, Quebec and New Brunswick to avoid eating romaine lettuce and salad mixes containing romaine unless consumers can identify where it came from.

"We're hopeful that it's moving in the right direction", Williams said. States with cases include California, Connecticut, Florida, Illinois, Louisiana, Massachusetts, Maryland, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island and Wisconsin. Officials said they believe the E. coli somehow ended up in the water used for irrigation. "Therefore, the water from the reservoir on this single farm doesn't fully explain what the common source of the contamination", the FDA stated.

"What we are seeing is there are multiple distributors and multiple processors and multiple farms that show up in the various legs of that traceback and they don't all lead back specifically to this farm", said Dr. Stephen Ostroff, Senior Advisor to the FDA commissioner. Any romaine of uncertain origin should not be sold, purchased or eaten, they said.

CNN has reached out to Adam Bros. Most strains are harmless.

Symptoms of illness linked to E. coli include intense stomach cramps, vomiting and potentially bloody diarrhea, and the CDC does not recommend antibiotics to treat infections from this strain.

This positive sample was collected by the FDA and analyzed by the CDC and determined to match the outbreak strain of E. coli through Whole Genome Sequencing analysis, the most precise DNA analysis available.
