The CDC and FDA are investigating a multistate outbreak of E. coli.

According to the recall, the E. coli infections are linked to romaine lettuce harvested from the Salinas, California growing region.

The organizations are advising customers not to eat any romaine lettuce from the Salinas region.

According to the release, most lettuce products show the harvest location on labels.

The recall includes all romaine lettuce harvested in the Salinas area, including whole heads of lettuce, hearts of romaine, packages of precut lettuce, and salage mixes that contain romaine.

Anyone with romaine lettuce at home should look at the label and make sure it was prepared outside of the Salinas region. If the label says Salinas or does not have a location on it, throw it away.

Those buying lettuce at a store should also check the labels and not purchase any with Salinas or no region listed.

A map showing the reported cases of E. coli related to the recall includes Ohio with five cases and Pennsylvania with three cases.

After the announcement of the CDC and FDA investigation, Missa Bay, LLC, recalled salad products for potential E. coli contamination.

Those products have "use by" dates ranging from October 29 to November 1.

Some symptoms of E. coli include nausea, vomiting, stomach cramps, diarrhea, fever, and loss of appetite.

The Panera Bread location in Austintown has signs posted noting the recall.
