"The Public Health Agency of Canada is no longer advising individuals in affected provinces to consider consuming other types of lettuce, instead of romaine lettuce".
Illnesses started on November 15 through December 8, 2017.
In an interview with NBC News, a CDC official said that even though Canadian authorities have linked the outbreak to romaine, US food safety workers haven't been able to identify a single food consumed by everyone affected.
The Centers for Disease Control and Prevention say there have been seven new E. coli cases in the United States regarding the ongoing outbreak. Among the 18 ill people for whom CDC has information, nine were hospitalized, including one person in California who died.
Cases by state is as follows: California (4), CT (2), IL (1), IN (2), Maryland (3), MI (1), Nebraska (1), New Hampshire (2), New Jersey (1), NY (1), OH (1), Pennsylvania (2), Vermont (1), Virginia (1), and Washington (1).
Which is why, although Canadian officials urged consumers to avoid romaine lettuce, USA health authorities have not yet identified which type of "leafy greens" had led to the spread of the illness.
PHAC has issued an updated public health notice stating that the E. coli O157:H7 foodborne illness outbreak in Canada, which it said was associated with Romaine lettuce consumption, appears to be over. Some companies, like the fast food chain Wendy's, and Compass, the country's largest food service company, have voluntarily withdrawn all romaine lettuce for now.
Symptoms of E. coli typically begin two to eight days after consuming the bacteria. Some individuals may develop a severe illness called hemolytic uremic syndrome, or HUS, which can be life-threatening, although most people recover in a few weeks.
She said American consumers "deserve more than this slow and insufficient response" and that families are "now left wondering if the food they are eating is safe". CR said it's also important to remember it's not just the romaine found at the grocery store, but also what people may find in a cafeteria or restaurant. If you are concerned that you have an E. coli infection, talk to your healthcare provider.
