Onion Handling & Training Requirements for Denver Food Service Workers

Colorado Food Handler Certification & Onion-Specific Requirements

All Denver food service workers must obtain a valid Food Handler Certificate through an DPHE-approved course within 30 days of hire. While general food handler training covers vegetables like onions, the course emphasizes temperature control, cross-contamination prevention, and personal hygiene. For higher-risk roles (managers, supervisors), DPHE requires Colorado Food Protection Manager Certification, which includes detailed protocols for produce receiving, storage, and washing. Online courses are available and typically take 2–3 hours to complete. Renewal is required every 3 years in Colorado.

Safe Onion Handling & Storage Procedures

Onions should be received at proper temperatures (ambient room temperature is acceptable; avoid warm or wet deliveries) and inspected for mold, soft spots, and pest damage per USDA guidelines. Store onions in a cool, dry, well-ventilated area separate from raw proteins and ready-to-eat foods to prevent cross-contamination. Cut onions must be refrigerated at 41°F or below and used within 3–4 days; raw whole onions can be stored for 2–4 weeks. All cutting boards and utensils used for onions must be cleaned and sanitized before contact with other foods. Never reuse water from onion washing for other tasks.

Common Onion-Related Violations & Health Department Enforcement

Denver DPHE inspection reports frequently cite improper onion storage (onions left at room temperature near ready-to-eat foods), failure to date cut onions, and inadequate cleaning of cutting surfaces after onion prep. Violations of Colorado food code (12.59.0002) can result in fines ranging from $50–$300 for non-critical violations and $300–$1,000+ for critical violations that pose imminent health risk. Repeat violations trigger mandatory retraining and follow-up inspections.
