Shigella Prevention Guide for Memphis Food Service

Hand Hygiene & Employee Health Screening Protocols

Shigella transmission begins with contaminated hands—the CDC identifies hand washing as the single most effective prevention measure. Implement mandatory handwashing stations with hot water, soap, and single-use towels at food preparation areas, restrooms, and after handling raw foods. Require employees to report gastrointestinal symptoms (diarrhea, abdominal cramps, fever) before shifts begin; the Shelby County Health Department recommends excluding symptomatic workers for at least 48 hours after symptoms resolve. Maintain written health screening logs and train staff on proper handwashing technique (20 seconds minimum), including nail beds and wrist areas where Shigella bacteria hide.

Sanitation & Cross-Contamination Prevention

Shigella survives on surfaces and food contact equipment, requiring rigorous daily sanitation. Use EPA-approved sanitizers on all work surfaces, cutting boards, and utensils between tasks—especially after handling raw foods or restroom breaks. Separate raw produce from ready-to-eat foods in storage and preparation areas to prevent cross-contamination. The Tennessee Department of Health enforces CFR Title 21 Part 117 standards for facility cleanliness; schedule professional deep cleaning monthly and maintain documentation. Dedicate separate cutting boards and utensils for produce, proteins, and ready-to-eat items, with color-coded systems for quick identification by staff.

Temperature Control & Food Monitoring

While Shigella primarily spreads through fecal-oral transmission rather than heat, maintaining proper food temperatures (165°F for high-risk foods) prevents secondary bacterial contamination that compounds outbreak severity. Monitor cold storage temperatures (41°F or below) for ready-to-eat foods, as Shigella can survive refrigeration for extended periods. Use calibrated food thermometers daily and log temperatures twice per shift; Shelby County Health inspectors verify these records during routine inspections.
