Walnuts Recalled From Natural Food Stores After E. Coli Outbreak

A California company is recalling organic walnuts that were sold at natural food stores and coop retailers in 19 states because of an E. coli outbreak that has sickened 12 people and hospitalized seven, federal officials said.

Gibson Farms, the company based in Hollister, Calif., is voluntarily recalling its shelled walnuts branded as Organic Light Halves and Pieces after discovering that the nuts could carry the E. coli strain O157: H7 that "causes a diarrheal illness often with bloody stools," the Food and Drug Administration said in a notice on Tuesday.

The recall came after the Centers for Disease Control and Prevention notified the company of 12 recorded illnesses that were linked to the walnuts. They were distributed at more than 300 food retailers, including Whole Foods Market, New Seasons Market and Rosauers Supermarkets, the F.D.A. said.

An investigation is underway to determine the potential source of the contamination, the F.D.A. said. The company did not immediately respond to inquiries on Wednesday.

E. coli symptoms can vary from person to person and may include cramping, diarrhea or gastrointestinal distress. Other common symptoms include vomiting and fever. People begin to feel symptoms three to four days after ingesting food or drinks containing the E. coli bacteria, according to the C.D.C.

A Whole Foods spokesman said the recalled walnuts were shipped to 10 of their Whole Foods Market stores across Arkansas, Louisiana and Texas and used only as an ingredient in a salad offered on salad bars in those stores. The salad item was removed from the salad bars and the recalled walnuts were destroyed immediately, the spokesman said.
