The CDC has issued some new guidance regarding the E.Coli outbreak affecting romaine lettuce.
After telling people last week to avoid all forms of the lettuce, federal food safety officials now say that you can eat some kinds of romaine, but you need to check the label to see where it's come from.
If the lettuce has come from the central coastal growing regions of northern and central California, don't buy it, sell it, serve it, or eat it.
The CDC has narrowed down the source of the E.Coli outbreak to that region of California, and says that lettuce grown in other common locations, such as Yuma, Arizona, the California desert area, Florida and Mexico, are not linked to the outbreak.
If there's no label at all, don't buy it for now. The CDC says that romaine lettuce products being distributed in the near future should have location labels on them, but it may take some time before it's a widespread practice.
Consumers, restaurants and retailers are also being told to check labels on bags or boxes of romaine, or ask suppliers about the source.
And if you have been keeping romaine in your refrigerator and don't know where it was harvested, the CDC advises you sanitize the drawers and shelves on which it was stored.
