Three more Canadian cases have been confirmed by the Canadian Public Health Agency on Friday, which is related to the Roman letter, on Friday.
This includes the number of people in 22 countries, including four cases in Ontario, 17 in Quebec and New Brunswick.
The agency said there was no evidence of other parts of Canada.
Some illness occurred at the end of October and early November, according to Dr. Howard Njoo according to the Canadian Public Health Agency.
There is a delay of 14 to 29 days while the patient is becoming an E. coli O157 infection. The tension behind the unexpected, he said.
When patients begin to experience symptoms, when they can get their diarrhea and vomiting, they can take the time before looking for medical attention. Once, a tobacco sample must be sent to the laboratory if it is an E. coli infection. If the evaluation is positive, local public health authorities will be notified and this information will be communicated to the provincial and federal officials.
The complaint condemns more than 30 people in the United States.
Rumors of bacteria damaged rumy lettuce to California, the US Food and Drug Administration (FDA) said on Friday.
This conclusion is based on "growing and letting patterns," FDA commissioner Dr Scott Gottlieb tweeted.
"Now it's time to burn a product that is in danger of being contaminated on the market and then reusing the market," he said.
The Canadian Food Inspection Agency said on Friday that the FDA was entering into its investigation information, which could not yet confirm the Romanian lettuce of Canada-grown canada in California.
OUTBREAKS UPDATE: Romanians involved in the contemporary scene are likely to be based on the growth and gathering of California models. Currently withdrawing the product at risk of contamination in the market and reusing the market …
Gottlieb said the FDA "means that the winegrowers do not have the effect of producing them". In fact, Roman lettuce would soon be in other parts of the United States, including Florida and Arizona.
Likewise, the agency wants more specific products to label "new standards" to help food trace back into the source, he said. The FDA "works with growers and distributors for labeling products on the day of storage and storage and other ways of informing consumers."
Labeling has shown that it was a challenge for research into food contamination, said Matthew Wise, the head of the Commission for the Advocacy of Pathological Control and Prevention of United States Diseases, said CBC News on Friday.
"One of the things we do not see in ships is where green leafy produce has grown," Wis said. "Several times bags are listed … the company's corporate headquarters or something like that.
He said that it is "almost impossible" to find out that someone who searches for a bag of lettuce, such as Arizona, California, Florida or Texas.
Another challenge in the production of E. coli on this stroke, Wise said, in fact, modest lettuce has a modest life.
"Among the trusted evidence … it is the discovery of food that causes the occurrence and the specific brush produced by foods," he said. "At that time, someone comes up with part of the event and we go back, for example, to the restaurant they eat … they are not the same lettuce they served for three weeks."
Although researchers continue to be infected with E. coli, they may even return to a specific region, but the exact source of bacteria is reduced. It can come from a farmer's field or water used for transport, distribution, or irrigation in a store.
On Green Leaves (including Roman Lettuce) on the occurrence of bacterial strain last year, Canadian and US officials did not determine the problem.
"It's a complex chain of distribution. Research is a tough product," said Wisek.
What people should do
The Canadian Public Health Agency continues to interest people in Ontario, Quebec and New Brunswick, to buy or eat mixes of Roman lettuce or lettuce.
If the people in these provinces were in the home of the Romans, they should be thrown into the container and cleaned and sanitized, including containers in the fridge.
The agency also advises that anyone who has had vomiting or diarrhea have experienced romaine lettuce to see their healthcare providers.
Canadian officials have advised people living in the provinces and territories in which case they are not taking action. The United States of Disease Control and Prevention has taken a much more aggressive disease to prevent any American consumers from avoiding Roman lettuce and throwing them away from home.
