Shigella Prevention in Los Angeles Food Service

LACDPH Requirements and California Food Code Compliance

Los Angeles County operates under California's Health and Safety Code Chapter 113 (Food Code), which mandates that food service facilities implement written food safety plans addressing Shigella risk. The LACDPH Environmental Health Division requires facilities to document employee health policies, especially screening for gastrointestinal illness symptoms (diarrhea, abdominal cramps, fever). California Food Code Section 113980 explicitly requires exclusion of food handlers suspected of Shigella infection. All facilities must maintain records of staff training, handwashing procedures, and illness reporting—violations result in administrative citations, fines up to $2,500 per violation, or temporary closure orders.

Contamination Sources and High-Risk Foods in LA Operations

Shigella is primarily transmitted through the fecal-oral route, making infected food handlers the most common source in commercial kitchens. Raw and ready-to-eat produce (leafy greens, berries, fresh herbs) can harbor Shigella if contaminated during harvest, washing, or handling with non-potable water. Imported produce from regions with inadequate sanitation presents elevated risk. Secondary transmission occurs when contaminated hands or surfaces (cutting boards, utensils, refrigeration handles) contact ready-to-eat foods. In LA's diverse food service environment—from food trucks to large catering operations—produce-heavy menus and high-volume batch preparation increase exposure risk if core controls are absent.

Prevention Protocols and Outbreak Reporting in California

Implement a food handler illness policy requiring employees to report symptoms immediately to management and stay home if symptomatic; LACDPH recommends a 48-hour symptom-free period before return to food handling duties. Enforce rigorous handwashing at dedicated sinks with soap and warm water for at least 20 seconds, especially after restroom use and before handling ready-to-eat foods. Source produce from reputable suppliers with documented food safety audits and traceability systems. When a Shigella case is suspected, California law requires immediate notification to LACDPH (available 24/7 for urgent reports). Facilities must cooperate with outbreak investigations, provide employee contact information, and retain food records for trace-back; failure to report is a misdemeanor under Health and Safety Code Section 120540.
