Norovirus Prevention Guide for Philadelphia Food Service (2026)

Philadelphia Health Department Sanitation Requirements

The Philadelphia Department of Public Health mandates three-compartment sink procedures with specific chemical concentrations for norovirus elimination. Food contact surfaces must be sanitized with EPA-approved disinfectants effective against enteroviruses; standard quaternary ammonia solutions are insufficient for norovirus. High-touch surfaces including door handles, cash registers, and POS terminals require hourly sanitization during suspected outbreak periods. Hand hygiene stations must include hot water (at least 100°F), soap, and single-use towels—soap-dispensing devices should be checked and refilled daily to prevent contamination.

Employee Health Screening and Exclusion Protocols

Philadelphia's Health Code § 6-203 requires food handlers with gastrointestinal symptoms to be excluded from work for at least 48 hours after symptoms resolve. Managers must document symptom-reporting procedures and maintain records of health statements signed by employees. Norovirus spreads through vomit and fecal matter, so employees handling ready-to-eat foods cannot return until fully symptom-free. Cross-training non-food service staff and maintaining backup staffing levels helps prevent understaffing-driven lapses in sanitation when key employees are excluded.

Temperature Controls and Raw Food Separation

Refrigeration must maintain 41°F or below; daily temperature logs are legally required and should include morning, mid-shift, and closing checks. Norovirus survives freezing, so cold storage prevents contamination only if raw products are kept separate from ready-to-eat items using designated shelving and color-coded cutting boards. Hot-held foods must reach 165°F internal temperature to inactivate other pathogens, though norovirus primarily transmits through contaminated hands and surfaces rather than through cooking temperature. Implement HACCP (Hazard Analysis Critical Control Point) procedures with validated time-temperature combinations for all high-risk items.
