Williams-Sonoma Pumpkin Seed Pesto was recalled by its manufacturer late Friday as the California Department of Public Health (CHPH) warned against eating it because of susceptibility to contamination from Clostridium botulinum, also known as botulism. Sutter-based California Olive and Vine LLC said in recalling the product that it was improperly processed. The pumpkin seed pesto 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. The Williams-Sonoma Pumpkin Seed Pesto has been sold nationwide at Williams-Sonoma retail stores since September 2014. Botulism toxin is odorless and colorless. Consumers who have any of these products or any foods made with these products should discard them immediately. Double-bag the jars in plastic bags and place in a trash receptacle for non-recyclable trash. Wear gloves when handling these products or wash your hands with soap and running water after handling any food or containers that may be contaminated. Botulism is a rare but serious paralytic illness caused by a nerve toxin that is produced by the bacterium Clostridium botulinum. The initial symptoms frequently experienced are double or blurred vision, drooping eyelids, and dry or sore throat. Progressive descending paralysis, usually symmetrical, may follow. Infants with botulism appear lethargic, feed poorly, are constipated, and have a weak cry and poor muscle tone. CDPH recommends consumers experiencing any ill effects after consuming these products should consult their health care provider. Consumers who observe the product being offered for sale are encouraged to report the activity to the CDPH toll-free complaint line at (800) 495-3232.
