Salmonella Prevention Guide for Seattle Food Service

Sanitation Protocols & Cross-Contamination Prevention

The Washington State Department of Health requires food service facilities to implement a Hazard Analysis Critical Control Point (HACCP) plan with specific focus on Salmonella vectors. Separate cutting boards, utensils, and prep surfaces must be designated for raw poultry, eggs, and meat—never cross-contact with ready-to-eat foods. Clean and sanitize all food contact surfaces with EPA-approved sanitizers between uses; the Seattle & King County Health Department mandates a minimum concentration of 200 ppm chlorine or equivalent quaternary ammonium compounds. Pay special attention to hand-contact surfaces, door handles, and ice scoops, which are common transmission points.

Employee Health Screening & Symptom Management

Washington State Food Safety Rules (WAC 246-215) require food handlers with symptoms of gastrointestinal illness—including diarrhea, vomiting, or jaundice—to be immediately excluded from food preparation. Managers must document illness reports and maintain a symptom log. Employees who have confirmed Salmonella infections require written medical clearance from a physician before returning to work. The Seattle & King County Public Health Department recommends offering paid sick leave policies to prevent ill workers from coming to work under financial pressure. Train all staff on proper handwashing (20 seconds with soap and warm water) after restroom use, handling raw foods, and touching contaminated surfaces.

Temperature Control & Cooking Guidelines

Salmonella is destroyed at an internal temperature of 165°F (74°C) for poultry and 160°F (71°C) for ground meats and eggs, per FDA Food Code standards adopted by Washington State. Use calibrated meat thermometers to verify doneness at the thickest part of the product; visual cues alone are insufficient. Maintain cold holding temperatures at 41°F (5°C) or below for raw and cooked potentially hazardous foods, and hot holding at 135°F (57°C) or above. The Seattle & King County Health Department conducts routine inspections with temperature spot-checks; document all cooking and holding temperatures in daily logs. Implement a preventive maintenance schedule for refrigeration units to ensure consistent temperature performance.
