Onion Handling Training Requirements for San Francisco Food Service

San Francisco Food Handler Certification & Onion-Specific Training

All food service workers in San Francisco must complete an approved Food Handler Card course that covers the California Health and Safety Code requirements, including produce handling standards. The SF Department of Public Health recognizes multiple accredited training providers that deliver online and in-person courses covering proper onion storage temperatures (50–70°F for whole onions, refrigeration for cut onions), washing procedures, and preventing cross-contamination with raw meats and allergens. Workers must pass an exam and renew certification every three years. Training specifically addresses how onions can harbor soil-borne pathogens and the importance of hand hygiene when handling both whole and pre-cut onions.

Safe Onion Handling & Storage Procedures

Whole onions must be stored in a cool, dry, well-ventilated area away from direct sunlight, with temperatures between 50–70°F to prevent sprouting and pathogen growth. Cut or sliced onions require refrigeration at 41°F or below and must be used within 3–5 days; they should never be left at room temperature for more than 2 hours (1 hour if ambient temperature exceeds 90°F). All onions must be washed thoroughly under running water before cutting and stored in clean, sanitized containers separate from raw proteins to prevent cross-contamination. Workers must change cutting boards and utensils between tasks and practice proper hand washing before handling onions, especially after touching raw meat or using restrooms.

Common Onion Handling Violations in San Francisco

The SF Department of Public Health regularly documents violations including improper storage temperatures for cut onions, failure to wash onions before preparation, and cross-contamination incidents where raw onions contact cooked or ready-to-eat foods on shared surfaces. Unmarked or improperly dated onion prep containers, storage of onions in unsanitized containers, and allowing onions to remain at unsafe temperatures during service are frequent citations. Operations that fail to provide documented food handler training to staff or allow untrained workers to handle produce may face citations under SF Health Code violations.
