Hepatitis A Prevention Guide for Seattle Food Service

Hand Hygiene and Employee Health Screening in Seattle

Washington state law requires food handlers to maintain rigorous hand hygiene practices, especially after using restrooms, handling raw foods, or taking breaks. The Seattle-King County Health Department mandates that employees with symptoms of viral hepatitis—jaundice, abdominal pain, dark urine, or pale stools—must be excluded from work and reported to the health department. Implement daily health self-checks at the start of shifts and maintain documentation of employee health status. Many Seattle facilities now use real-time illness reporting systems to flag symptomatic staff before they contaminate food or surfaces.

Sanitation Protocols Specific to Hepatitis A Pathogens

Hepatitis A virus survives longer on food-contact surfaces than many bacteria, requiring bleach-based sanitization at Seattle-licensed facilities. The Washington Food Safety Code specifies using 100–400 ppm chlorine solution (or EPA-approved quaternary ammonium compound) on all food-contact surfaces, with emphasis on restroom door handles, POS terminals, and produce prep areas. Implement hourly sanitization logs during peak service hours and verify that your chemical concentration is tested with sanitizer strips. Hot water handwashing stations must be accessible on the line and in all prep areas; cold water alone does not kill Hepatitis A virus and violates Seattle health department standards.

Temperature Control, Produce Handling, and Alerts

While Hepatitis A is not destroyed by cooking (infection occurs before food reaches the kitchen), proper food storage temperature prevents secondary bacterial contamination that compounds risk. Seattle facilities must maintain refrigeration logs and ensure produce—high-risk for Hepatitis A if harvested from contaminated water—is sourced from verified suppliers. Monitor FDA and CDC recall alerts through real-time platforms to catch Hepatitis A-linked produce recalls within hours, not days. The Seattle-King County Health Department coordinates with the Washington State Department of Health to issue alerts; subscribe to their listservs and use food safety monitoring tools that aggregate FDA, FSIS, and CDC notifications in one dashboard.
