But as of 11.20pm on Wednesday (Nov 21) local time, neither the Agri-Food and Veterinary Authority of Singapore (AVA) nor the US Centres for Disease Control and Prevention (CDC) had issued a recall for romaine lettuce. The agency is warning people to throw out all romaine, because of fears it may carry a potentially deadly strain of E. coli. If you have eaten romaine lettuce in the past week and have been ill with similar symptoms, see your doctor. The issue isn't limited to the USA, as 18 people in Canada have also fallen ill.
Officials didn't identify any particular brand in the outbreak that took place in the spring of this year either.
So far there are no deaths or reports of outbreaks in Florida.
"If you look at the map of illness onsets from past year, it is very similar to this recent outbreak....because these two are related, we have really more clues to go by now in terms of where people got sick and the timing involved", Horsfall said. No one wants to get to the bottom of how these outbreaks are occurring faster than the producers of leafy greens.
"Food safety is the produce industry's top priority". That outbreak was eventually traced to Arizona. Whole genome sequencing showed that the E. coli strains that made people sick in Canada and in the United States were closely related genetically. The company says it will continue working with regulators as their investigation continues. Ultimately, that rule may not be implemented, Sorscher said. That's why health officials are warning against all romaine.
The case was first reported to Ottawa Public Health on October 26. Here in Canada, the country's public health and food inspection agencies stopped short of insisting on its removal, though it did advise people in Ontario and Quebec to stop eating romaine lettuce.
All items containing romaine lettuce are being pulled from shelves across Canada within Sobeys' national store network.
Finally, turkeys have not been recalled, but more than 74 cases of salmonella have been linked to raw turkey.
