San Diego, California – County Public Health officials are urging residents to discard walnuts linked to a national E. coli outbreak that were sold in local natural food stores and co-ops. Two individuals who consumed the walnuts from these stores have fallen ill due to the same strain of E. coli involved in a multi-state outbreak primarily associated with Gibson Farms walnuts. One local individual required hospitalization due to the illness.

The contaminated walnuts produced by Gibson Farms Inc. have the potential to cause severe health issues, including hospitalization and even death, due to the presence of Shiga toxin-producing E. coli. As a result, the company has issued a nationwide recall of the affected products.

These walnuts were sold either halved or in pieces from bulk bins starting as early as October 1, 2023. Additionally, some stores may have repackaged and sold the walnuts in individual bags or takeout containers for customer convenience. The County has been collaborating with local stores that received shipments of the recalled walnuts to ensure that all affected products have been removed and storage bins thoroughly disinfected as of May 3.

Stores involved in the recall and subsequent cleanup process include Jimbos Naturally in San Diego (4S Ranch, Carmel Valley, Carlsbad, Escondido), Lazy Acres Market in San Diego and Carlsbad, Ocean Beach Co-Op, Frazier Farms Market in La Mesa and Vista, and Sun Organic Farm in San Marcos.

If individuals suspect they have purchased the affected walnuts, they are advised not to consume them and to properly dispose of them. It is also recommended to wash any containers or surfaces that may have come into contact with the walnuts using hot soapy water or a dishwasher to prevent any further contamination.

E. coli infection can present with severe symptoms such as stomach cramps, diarrhea, and vomiting, typically occurring within three to four days of exposure. Dr. Wilma J. Wooten, the County public health officer, emphasized the importance of seeking medical attention promptly if one experiences symptoms, as E. coli can lead to severe kidney problems requiring hospitalization.

According to the Centers for Disease Control and Prevention (CDC), cases linked to the contaminated walnuts have also been reported in Washington state. Public health officials continue to monitor the situation closely, urging vigilance and caution among individuals who may have come into contact with the affected products.
