Hepatitis A Prevention in Houston Food Service: Local Compliance Guide

Common Hepatitis A Sources in Houston Food Service

Hepatitis A spreads primarily through fecal-oral contamination, making infected food handlers the leading risk in Houston establishments. The virus commonly enters food through contaminated produce (particularly imported berries and leafy greens), raw shellfish from Gulf waters, and inadequately cooked foods handled by positive individuals. The Houston Health Department and DSHS track these source patterns closely, as the virus survives freezing and requires 185°F temperatures for 1 minute to be inactivated. Understanding your supply chain—especially produce sourcing and shellfish suppliers—is critical for Houston-area operators.

Houston-Specific Prevention & Handler Protocols

The Houston Health Department enforces strict hand hygiene and health screening protocols aligned with FDA Food Code standards. All food handlers must undergo health screening upon hiring; anyone with confirmed or suspected Hepatitis A cannot work until cleared by DSHS. Houston establishments must implement documented handwashing stations, exclude symptomatic employees (fever, jaundice, abdominal pain), and maintain records of employee health certifications. The Texas Health & Safety Code § 431.021 mandates daily health observations; consider real-time alerts for employee illness reporting to prevent cross-contamination during high-risk periods like summer months when transmission increases.

Texas DSHS Reporting & Outbreak Response Requirements

Confirmed or suspected Hepatitis A cases in food service must be reported to the Texas Department of State Health Services within 1 business day under 25 TAC § 97.1. Houston establishments are also required to notify the Houston Health Department immediately if an employee tests positive or shows symptoms. DSHS conducts rapid epidemiological investigations to trace source contamination and identify exposed customers; you must cooperate fully and provide employee schedules, supplier records, and customer lists. Failure to report can result in fines and operational suspension. Post-exposure prophylaxis (PEP) information must be provided to potentially exposed patrons, and deep sanitization protocols—beyond standard procedures—are typically required before reopening.
