Shigella Prevention Guide for Portland Food Service

Employee Health Screening & Hygiene Protocols

Shigella spreads primarily through fecal-oral contact, making employee health screening essential. Portland food service facilities must require employees to report gastrointestinal symptoms including diarrhea, abdominal cramps, and fever before starting shifts. Implement mandatory handwashing stations with hot water and soap at employee entrances, food prep areas, and restrooms—the CDC identifies handwashing as the single most effective Shigella prevention measure. Require employees to wash hands for at least 20 seconds after using restrooms, handling raw foods, and touching their faces. For staff confirmed with Shigella infection, the Multnomah County Health Department typically requires exclusion from work until symptom-free for 24 hours, though clearance rules may vary; consult your local health officer for specific guidance.

Sanitation & Cross-Contamination Prevention

Shigella contamination often occurs through inadequate cleaning of food contact surfaces and cross-contamination from raw to ready-to-eat foods. Establish daily sanitation schedules using EPA-approved sanitizers effective against Shigella (quaternary ammonium or chlorine-based solutions at proper concentrations). Separate raw produce, meats, and ready-to-eat foods using designated cutting boards, utensils, and prep areas—the FDA Food Code prohibits cross-contact to prevent pathogen transfer. Pay special attention to areas employees touch frequently (door handles, time clocks, cash registers) and restroom surfaces, as Shigella can survive on environmental surfaces for hours. Document all sanitation activities and maintain records for health department inspections, as the Oregon Health Authority requires food service facilities to demonstrate compliance with sanitation standards.

Temperature Control & Food Safety Monitoring

While Shigella is primarily a hygiene-related pathogen rather than a temperature-dependent threat, maintaining proper cooking and holding temperatures prevents cross-contamination and supports overall food safety. Cook potentially hazardous foods to minimum safe internal temperatures verified with calibrated thermometers—raw vegetables and ready-to-eat foods cannot be cooked, making employee hygiene the primary control. Keep hot foods at 135°F (57°C) or above and cold foods at 41°F (5°C) or below during storage and service. The FDA Food Code and Portland-Multnomah County Health Department require food service operations to maintain time-temperature logs and conduct regular health inspections.
