FDA thinks they know where tainted romaine likely came from

Health officials in the USA and Canada told people Tuesday to stop eating romaine lettuce because of a new E. coli outbreak.

In the USA, there have been at least 32 reported illnesses across 11 states related to the outbreak.

Whether it's purchased from a grocery store or served in a restaurant, many North Americans are staying away from romaine lettuce. Although many people have reported eating romaine lettuce and the CFIA believes the problems are related to the lettuce, none of the lettuce they have tested so far has shown signs of E. coli. People are also being advised to throw out any romaine they have at home.

Those who have symptoms of an E. coli O157 infection are urged to talk to their medical provider. It doesn't help that both states are quite hot and romaine lettuce already requires an abundance of water, he said.

With a series of E. coli outbreaks and contaminated romaine lettuce sweeping across the United States, the South Korean government has attempted to assuage local concern by confirming that lettuce produced and distributed in South Korea is safe.

Although the outbreak is centred in Quebec and Ontario, grocery giants like, Loblaw, Sobeys and Walmart have chose to stop selling romaine lettuce at their stores nationwide.

"New romaine from different growing regions, including Florida and Arizona, will soon be harvested", Gottlieb tweeted.

"As partners in ensuring the health and safety of Canadians, retailers and restaurants should take appropriate action as per the advice provided to Canadians in the public health notice", agency spokeswoman Maryse Durette said in an email statement Wednesday evening.

As of Thursday, the CDC was still advising people not to eat any romaine lettuce.

What is E. coli 0157:H7?

The U.S. Food and Drug Administration (FDA), along with the Centers for Disease Control and Prevention (CDC), as well as state and local authorities are investigating on a multistate e.coli outbreak.

In Canada, based on the investigation findings to date, exposure to romaine lettuce has been identified as a source of the current outbreak, but the cause of contamination has not been determined, officials say.

"Most people with an [E. coli] infection start feeling sick three to four days after eating or drinking something that contains the bacteria".
