The U.S. Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC), in collaboration with state and local partners, are investigating an outbreak of Salmonella Thompson infections linked to fresh diced onions from Gills Onions of Oxnard, California.
Based on epidemiological data collected by CDC, 14 of 19 cases with information available reported exposure to fresh diced onions before becoming ill. Additionally, based on traceback data collected by FDA, FDA determined that onions processed at Gills Onions were available at points of service where people ate prior to becoming ill.
In response to this investigation, Gills Onions has voluntarily recalled diced yellow onion, diced onions & celery, diced mirepoix, and diced red onions.
The investigation is ongoing to determine the source of contamination and whether additional products are linked to illnesses. FDA will update this advisory should additional consumer safety information become available.
