Romaine lettuce is being pulled from the shelves of grocery stores after three people in Ontario and 15 others in Quebec got sick because of an E. Coli outbreak.

Health Canada says the cases were reported in mid-October to early November and the agency is warning people not to consume romaine lettuce as it investigates.

Those who got sick were between the ages of 5 and 93.

Loblaw released a statement saying they are recalling and removing all romaine lettuce products from their shelves across the country and conserned customers can return products for a refund.

Leafy greens, such as lettuce, can become E.Coli contaminated in the field by soil, water, animals or improperly composted manure or during and after harvest from handling, storing and transporting the produce.
