Fastexy Exchange|E. Coli recalls affect 20 states, DC. See map of where recalled food was sent.

Two recalls over food potentially contaminated by E. Coli have Fastexy Exchangebeen making national headlines all week and adding some unneeded stress to grocery store trips.

Cargill Meat Solutions recalled over 16,000 pounds of ground beef shipped to Walmart stores across 11 states and Washington, D.C., the U.S. Department of Agriculture announced Wednesday.

Infections in two states – California and Washington – have been linked to organic walnut halves and pieces sold in bulk bins at natural food and co-op stores. The infected walnuts, from Gibson Farms, Inc. of Hollister, California, led the U.S. Food and Drug Administration and the Centers for Disease Control and Prevention to conduct a multi-state investigation.

There are currently no overlapping states in the recalls, as the potentially contaminated walnuts were sent to 19 states primarily in the Midwest and West coast, and the ground beef was distributed to Walmart stores on the East coast.

Here's what to know:

Which walnuts are affected by the recall?

• The expiration dates are from May 21, 2025 to June 7, 2025.

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.

Health officials reported 12 illnesses and seven hospitalizations in California and Washington connected to the organic walnuts, according to the CDC.

The USDA said that there have been no reports of people falling ill from the potentially contaminated ground beef.
