Staphylococcus aureus Prevention for St. Louis Food Service

Sanitation Protocols & Hand Hygiene Standards

The City of St. Louis Department of Health requires food service establishments to implement rigorous hand hygiene and surface sanitation to prevent Staphylococcus aureus transmission. Staff must wash hands with soap and warm water for at least 20 seconds before food preparation, after handling raw foods, after using the restroom, and after touching hair or face. All food contact surfaces, cutting boards, and utensils must be cleaned with hot soapy water and sanitized with approved chemical sanitizers (200 ppm chlorine solution or equivalent) at least every four hours during service. Pre-packaged sanitizer test strips should verify sanitizer concentrations meet regulatory standards. Separate colored cutting boards for raw proteins, produce, and ready-to-eat foods prevent cross-contamination from Staph aureus-carrying raw foods.

Employee Health Screening & Exclusion Policies

St. Louis health code requires food service employers to screen employees for symptoms associated with Staphylococcus aureus and other pathogens before shifts begin. Staff with open wounds, cuts, sores, or boils on hands and forearms must be excluded from food preparation until wounds are completely healed or properly bandaged and covered with impermeable gloves. Employees with symptoms of skin infections, respiratory illness, or gastrointestinal distress should not handle food. The FDA Food Code, which St. Louis food safety ordinances align with, mandates that operators maintain written health policies and document health-related exclusions. Training all staff on proper illness reporting protects customers and reduces liability. Consider implementing a daily sign-in sheet where employees confirm they are symptom-free.

Temperature Control & Holding Requirements

Staphylococcus aureus thrives in the temperature danger zone (41°F–135°F) and produces heat-stable toxins that survive cooking. St. Louis Department of Health requires hot foods to be held at 135°F or above and cold foods at 41°F or below at all times. Use calibrated thermometers to verify internal temperatures of cooked foods: poultry must reach 165°F, ground meats 155°F, and whole cuts 145°F. Cooked foods contaminated with Staph aureus after preparation must never be reheated for service. Implement a HACCP (Hazard Analysis Critical Control Point) plan that identifies Staph aureus contamination points and establishes critical control limits. Monitor holding equipment daily and maintain temperature logs as required by city health department inspections. Discard any food held in the danger zone for more than four hours.
