After a serious recall of romaine lettuce last week, the FDA and CDC is giving the okay to eat the vegetable again as long as it doesn't come from northern and central California.
The lettuce, linked to an outbreak of E. coli, has now made 43 people sick across 12. Another 22 have fallen ill in Canada as well.
Officials haven't narrowed down a single grower or distributor, just that the lettuce was harvested in northern and central California, CNBC reports. While some romaine is now safe to be eaten, the agencies urge consumers to not eat the lettuce if they don't know where it came from.
"Over the Thanksgiving holiday, the FDA continued to investigate the outbreak. Our investigation at this point suggests that romaine lettuce associated with the outbreak comes from areas of California that grow romaine lettuce over the summer months, and that the outbreak appears to be related to 'end of season' romaine lettuce harvested from these areas," FDA commissioner Dr. Scott Gottlieb said in a statement.
The FDA is currently working on ways to better identify the source of future food-borne outbreaks. The agency is urging stores and distributors to label lettuce by origin so that consumers are safe.
