Unfortunately, this is the SECOND outbreak linked to Romaine Lettuce in 2018. Obviously, Romaine Lettuce has not had the best year. Lowlaws, Sobeys and Loblaws have all announced that they are pulling Romaine Lettuce from their shelves Nationwide.
Costco has just announced that as a precaution, they will be pulling Romaine Lettuce and salad mixes containing Romaine Lettuce from all warehouses across Canada and the USA. So if you had plans to include this in your menu planning over the next couple of days, maybe try something else?

I want to be clear in saying that there is no evidence to suggest that residents in other parts of Canada are affected by this outbreak, but that being said, if you don’t feel comfortable consuming your remaining package of Romaine Lettuce, please take advantage of Costco’s satisfaction guarantee and return it for a full refund.
