Hepatitis A Outbreaks in Los Angeles: What You Need to Know

How Hepatitis A Spreads Through LA's Food Supply

Hepatitis A virus spreads primarily through fecal-oral contamination when infected food handlers prepare meals without proper handwashing, or when contaminated produce and shellfish reach consumers. The virus survives on surfaces and in food longer than many pathogens, making it particularly dangerous in commercial kitchens and food processing facilities. Raw or undercooked shellfish from contaminated waters—including those harvested near California's coast—pose significant risk. Produce like berries, leafy greens, and frozen items have been linked to outbreaks affecting Los Angeles residents. Unlike bacteria, hepatitis A cannot be killed by freezing, making prevention through proper food handling essential.

LA County Health Department Response & Outbreak Tracking

The Los Angeles County Department of Public Health investigates hepatitis A cases, identifies sources, and issues public health alerts through its website and emergency bulletins. When outbreaks are confirmed, the department works with restaurants, food producers, and retailers to trace contaminated products and remove them from shelves. The California Department of Public Health coordinates statewide tracking, sharing data with the CDC when outbreaks cross county or state lines. Health inspectors conduct enhanced facility inspections and food handler interviews to identify the transmission route. LA residents can check the county health department's website for active outbreak notices and recalled products specific to Los Angeles.

Protecting Yourself & Your Family During LA Hepatitis A Outbreaks

Practice strict handwashing with soap and warm water for at least 20 seconds, especially after using the restroom and before eating—this is your primary defense against hepatitis A. Cook shellfish to an internal temperature of 145°F and wash all produce thoroughly under running water, even items you'll peel or cut. Avoid eating raw or undercooked shellfish from untested or contaminated waters, and be cautious with pre-prepared foods from establishments with health violations. Real-time food safety alerts from sources tracking FDA, FSIS, and LA County health data help you avoid contaminated products before they reach your table. If you experience jaundice, abdominal pain, or fatigue after potential exposure, contact your doctor immediately—early detection prevents severe illness.
