Norovirus Prevention Guide for San Antonio Food Service

San Antonio Health Department Sanitation Standards for Norovirus

The San Antonio Metropolitan Health District enforces food service sanitation rules derived from the Texas Food Establishments Rules, which incorporate FDA guidance on norovirus prevention. All food contact surfaces must be cleaned with hot water (at least 171°F) and approved sanitizers; norovirus requires higher sanitizer concentrations than many bacteria, so use EPA-registered disinfectants proven effective against enveloped viruses. Handwashing stations must be accessible throughout food prep areas, and staff should wash hands with soap and warm running water for at least 20 seconds—particularly after using restrooms, handling money, or touching face/hair. San Antonio inspectors specifically look for documentation of sanitizer concentration testing using test strips, so maintain daily logs verifying proper chemical levels in your three-compartment sinks and spray bottles.

Employee Health Screening & Exclusion Protocols

Texas Food Establishments Rules require food workers with symptoms of acute gastroenteritis (vomiting, diarrhea) to be excluded from food preparation immediately. Because norovirus can shed in saliva and feces, implement a health attestation system requiring employees to report symptoms before their shift—this reduces asymptomatic transmission. If an employee develops norovirus symptoms during work, they must be removed from food handling; consult the San Antonio Metropolitan Health District if you suspect an outbreak. Document all illness reports and exclusions in writing, as health inspectors review these records during investigations. Consider requiring a symptom-free period of at least 48 hours after the last vomiting/diarrhea episode before employees return to food prep duties.

Temperature Control & Cross-Contamination Prevention

While norovirus is primarily transmitted through contaminated surfaces and fecal-oral routes rather than undercooked food, proper temperature management prevents cross-contamination and supports overall food safety culture. Raw produce used in ready-to-eat dishes should be from verified suppliers and washed thoroughly; San Antonio's high heat means ready-to-eat items stored at room temperature are higher-risk. Implement separate cutting boards, utensils, and prep areas for raw produce versus cooked foods, and never allow food handlers with gastrointestinal illness to touch any food items.
