California Department of Public Health (CDPH) Director and State Health Officer Dr. Ron Chapman warned consumers today not to eat Williams-Sonoma Pumpkin Seed Pesto sauce because it may have been improperly produced, making it susceptible to contamination with Clostridium botulinum.

Ingestion of botulism toxin from improperly processed jarred and canned foods may lead to serious illness and death.

The manufacturer of the product, California Olive and Vine, LLC, of Sutter, California, initiated the voluntary recall after CDPH determined that the product had been improperly processed. The product was packaged in eight ounce glass jars with screw-on metal lids. The recalled product can be identified by the following stock keeping unit (SKU) numbers: 6404305 and 6389043. Photographs of the affected product package are located on the Recalled Product Photo Page. The Williams-Sonoma Pumpkin Seed Pesto has been sold nationwide at Williams-Sonoma retail stores since September 2014.
