Shigella Prevention for San Antonio Food Service Operators

San Antonio & Texas Regulatory Requirements for Shigella Control

The San Antonio Metropolitan Health District follows Texas Department of State Health Services (DSHS) Food Establishment Rules, which mandate specific controls for pathogenic bacteria including Shigella. Food service operators must implement active monitoring systems, maintain documented employee health policies, and report confirmed or suspected cases to the health district within 24 hours as required by Texas Administrative Code §275.1. San Antonio establishments must maintain handwashing stations with hot and cold running water, soap, and single-use towels—non-negotiable controls that directly reduce Shigella transmission from infected handlers.

Identifying High-Risk Sources: Produce, Water & Food Handlers

Shigella is commonly found in raw fruits and vegetables, particularly in imported produce and items from areas with inadequate water sanitation. San Antonio food service operations should source produce from suppliers with verified water-quality testing and implement produce washing protocols using approved sanitizers. Infected food handlers represent the primary transmission vector; Texas requires operations to restrict employees with gastrointestinal illness (diarrhea, abdominal cramping) from food handling for at least 24 hours after symptom resolution. Cross-contamination risk increases in high-volume settings—proper separation of raw and ready-to-eat foods, designated cutting boards, and color-coded utensils are critical control measures.

Prevention Protocols & Compliance Monitoring

Implement a documented Hazard Analysis Critical Control Point (HACCP) plan specific to Shigella risks, with handwashing frequency verification, produce supplier audits, and staff training records. The San Antonio Metropolitan Health District conducts unannounced inspections and reviews food handler certification compliance; ensure all staff complete Texas Food Handler certification covering pathogens and hygiene. Maintain temperature logs for cold storage, monitor chlorine levels if using well water (minimum 0.5 ppm free residual), and establish a symptom-reporting protocol requiring employees to notify management of diarrhea, nausea, or abdominal pain. Document all corrective actions and share them with health inspectors—compliance records demonstrate due diligence if an outbreak occurs.
