Onion Safety Guide for Seattle Consumers & Restaurants

Seattle & Washington State Onion Handling Regulations

The Washington State Department of Health enforces food safety standards through the Washington Food Safety Code, which requires all food handlers—including restaurants and produce retailers—to maintain proper temperature control, cross-contamination prevention, and traceability for produce. Raw onions must be stored separately from ready-to-eat foods and cannot be kept in conditions exceeding 41°F if cut. Seattle-King County Public Health Department conducts regular inspections of food service establishments to verify compliance with these standards. Restaurants must maintain detailed supplier documentation and recall procedures aligned with FDA regulations.

Common Onion Contamination Risks & Recent Patterns

Salmonella is the primary pathogen associated with raw onion outbreaks, historically linked to irrigation water, soil contact, and post-harvest processing. The FDA and CDC have investigated multi-state onion-associated Salmonella clusters in recent years, with contamination occurring both domestically and in imported products. E. coli and Listeria monocytogenes are less common but documented risks in cut or processed onion products. Cross-contamination during slicing, dicing, or prep—particularly when using shared cutting boards without sanitization—significantly increases risk in commercial and home kitchens. Seattle restaurants handling high-volume produce should implement rigorous wash protocols and traceability systems to track supplier sources.
