Staphylococcus aureus Prevention Guide for Indianapolis Food Service

Employee Health Screening and Hygiene Protocols

The Indianapolis-Marion County Health Department requires food service employees to report illnesses, particularly symptoms of skin infections, boils, or infected cuts—common sources of Staphylococcus aureus transmission. Employees with active skin infections or pustules must be restricted from food contact until medical clearance is obtained. Implement daily health attestations and require hand washing with soap and warm water for at least 20 seconds before food handling, after restroom use, after touching face or hair, and after handling money or contaminated items. Single-use gloves must be changed frequently and are not a substitute for hand washing, as the pathogen can survive on hands and transfer to glove surfaces.

Temperature Control and Time-Temperature Management

Staphylococcus aureus toxins form during the "danger zone" between 40°F and 140°F, typically within 2-4 hours of contamination. Indianapolis food service operations must maintain hot foods at 135°F or above and cold foods at 41°F or below, verified with calibrated thermometers checked daily. Ready-to-eat foods prepared in-house must be cooled from 135°F to 70°F within 2 hours, then to 41°F within 4 additional hours—this two-stage cooling process prevents toxin production. Use ice baths, blast chillers, or shallow containers to accelerate cooling, and never leave prepared foods at room temperature during service gaps or shift changes.

Sanitation Protocols and Environmental Controls

Clean all food contact surfaces with hot soapy water, followed by a sanitizing solution (100-400 ppm chlorine or quaternary ammonium compound per FDA guidelines) at least between tasks and after handling raw proteins. High-touch areas—door handles, register keypads, ice scoops, and serving utensils—require hourly sanitization during service hours. Implement a documented cleaning schedule with staff initials and times, as required by Indianapolis-Marion County Health Department inspections. Prevent cross-contamination by using separate cutting boards for raw proteins versus ready-to-eat foods, and store cooked foods above raw products in refrigeration units.
