A recall of carrot products for potential E. coli contamination has been expanded, the Food and Drug Administration announced.

The agency announced on Nov. 29 that California-based 4Earth Farms was recalling multiple brands sold at different retailers in seven states out of abundance of caution after 4Earth was notified by Grimmway Farms that carrots used in its products may have been contaminated with E. coli.

All potentially-affected 4Earth Farms products have best-by dates ranging from Sept. 7 to Nov. 2 and should no longer be sold commercially, but may still be present in homes. No illnesses have been reported that are associated with this latest product recall.

More than a dozen brands of organic carrots were recalled in November for concerns about E. coli contamination. The Center for Disease Control and Prevention announced an investigation into an E. coli outbreak in multiple states tied to the carrots after one person died and 15 were hospitalized in connection to the outbreak.

Which products were included in the most recent recall?

The recalled 4Earth Farms products were sold in Florida, California, Pennsylvania, Illinois, New Hampshire, Colorado and Minnesota.

What is E. coli? What are the symptoms?

Most Escherichia coli (E. coli) bacteria reside harmlessly in the intestines of people and animals. But some can cause mild to life-threatening gastrointestinal illnesses if consumed, the CDC says.

The types of E. coli that may cause diarrhea usually spread through food or water contaminated with feces. For instance, food handlers can spread infection when they do not use proper hand washing hygiene after using the restroom. Animals such as cattle may also spread E. coli to food and food crops.

Symptoms of E. coli infection include severe stomach cramps, diarrhea (often bloody), and vomiting, according to the CDC.

The agency recommended seeking immediate medical attention if a person experiences:

• Diarrhea and a fever higher than 102°F
  • Diarrhea for more than 3 days that is not improving
  • Bloody diarrhea
• So much vomiting that you cannot keep liquids down
• Signs of dehydration, such as:
  • Not peeing much
  • Dry mouth and throat
  • Feeling dizzy when standing up
