San Francisco Restaurant Onion Violations & Health Code Compliance

Temperature Control & Cold Storage Violations

San Francisco health code requires cut onions and prepared onion mixtures to be stored at 41°F or below, consistent with California Food Code. Inspectors document violations when onions are left at room temperature, stored in inadequately refrigerated units, or kept beyond safe time limits. Common failures include pre-diced onions stored in walk-ins without proper temperature monitoring, bulk onion prep areas exceeding the 2-hour window before refrigeration, and hot-held onion dishes (like caramelized onions) not maintained at 135°F or above. SFDPH inspectors use calibrated thermometers to verify storage temperatures and review time-temperature logs during routine and complaint-driven inspections.

Cross-Contamination & Improper Storage Practices

Raw onions must be stored separately from ready-to-eat foods and below other proteins to prevent contamination, per SFDPH guidelines. Violations occur when bulk onions are stacked directly over prepared salads, cooked proteins, or ready-to-eat vegetables in shared storage units. San Francisco inspectors flag raw onions stored in the same containers as cooked foods, improperly labeled prep containers of cut onions, and onion scraps or peels left on shelves contaminating adjacent food surfaces. Facilities frequently receive critical violations when inspectors discover onion-soiled hands or cutting boards used immediately on ready-to-eat items without handwashing or sanitization breaks between tasks.

How San Francisco Inspectors Assess Onion Handling

SFDPH conducts routine, follow-up, and complaint-based inspections with emphasis on onion storage during peak prep hours. Inspectors visually examine refrigeration units, verify storage temperatures with thermometers, review food handler training records, and interview kitchen staff about storage duration. They document violations using the California Retail Food Code framework and assign severity levels: critical violations (immediate health hazard) typically include temperature abuse or severe cross-contamination, while major violations cover inadequate labeling or minor storage separation failures. Restaurants receive reinspection notices and must demonstrate corrective action within specified timeframes; repeated violations can result in operational restrictions or closure orders issued by SFDPH.
