Shigella Prevention Guide for Houston Food Service

Sanitation & Hand Hygiene Protocols

Shigella bacteria spread through fecal-oral routes, making hand hygiene the single most critical control point in food service. All staff must wash hands with soap and warm running water for at least 20 seconds after using restrooms, before food preparation, and after handling raw foods—per FDA Food Code Section 2-301.14. Install handwashing stations with hot water (at least 100°F) in food prep areas and restrooms, and maintain logs of daily sanitation verification. Houston facilities must comply with TCEQ Rule §229.262, which requires documented cleaning of all food contact surfaces with approved sanitizers (100 ppm chlorine or equivalent). Implement separate cleaning protocols for restroom facilities, where Shigella contamination risk is highest.

Employee Health Screening & Exclusion Policies

Harris County Health Department requires food handlers with symptoms of diarrhea, vomiting, or jaundice to be excluded from work immediately—per FDA Food Code Section 2-201.13. Shigella has a 1-3 day incubation period, so employees reporting gastrointestinal illness should not return to work until symptom-free for 24 hours without medication. Maintain confidential health attestation forms and establish a clear policy requiring staff to report illness before their shifts. Some cases warrant medical clearance; the Houston Health Department can advise on when testing is necessary. Cross-training backup staff ensures you can maintain service without pressuring ill employees to work through infections.

Temperature Control & Cross-Contamination Prevention

While Shigella primarily spreads through direct contact rather than temperature abuse, improper food handling accelerates contamination risk. Keep ready-to-eat foods at 41°F or below and maintain separate cutting boards, utensils, and prep spaces for raw and ready-to-eat items per TCEQ §229.262. Raw vegetables and salads—common Shigella vectors—should be washed with potable water and stored separately from raw proteins. Monitor and record cold storage temperatures daily, and calibrate thermometers monthly. When Shigella is identified in your supply chain or region (tracked through Panko Alerts' real-time FDA and CDC monitoring), increase frequency of surface sampling and reinforce hygiene drills with all staff.
