There have been 39 hospitalizations as of Tuesday, with six people suffering a type of kidney failure attributed to the outbreak, according to the CDC.
The CDC last week warned people not to eat any romaine lettuce harvested in Salinas.
The ban included "whole heads of romaine, organic romaine, hearts of romaine, romaine in salad wraps, and packages of precut lettuce and salad mixes which contain romaine, including baby romaine, spring mix and Caesar salad," the CDC said this week.
Most packages of romaine say where it was harvested, but if it doesn't, the CDC said to throw it away to be safe.
Officials also said if you have a salad or wrap and you don't know what type of lettuce is in it, throw it away.
Finally, make sure you clean and sanitize wherever you have stored the affected lettuce.
