Shigella Prevention Guide for Los Angeles Food Service
Shigella is a highly contagious bacterial pathogen that spreads rapidly in food service environments through fecal-oral contamination, often requiring only minimal infectious doses. Los Angeles restaurants and food businesses face documented Shigella outbreaks, making strict prevention protocols essential. This guide covers LA-specific sanitation standards, employee health policies, and temperature controls mandated by the Los Angeles Department of Public Health.
LA Health Department Sanitation & Handwashing Requirements
The Los Angeles County Department of Public Health enforces Title 7 California Code of Regulations, which mandates frequent handwashing with soap and warm running water (100°F minimum) for all food handlers, especially after restroom use. Shigella survives on hands and surfaces for hours, so your establishment must provide designated handwashing stations in every food prep area, restroom, and bar station with single-use paper towels. Implement a documented handwashing log, require employees to wash hands before food contact, after breaks, and every 2 hours during shifts. Use EPA-approved sanitizers (quaternary ammonium or chlorine-based) on all food-contact surfaces, with concentration levels verified by test strips twice daily per LA health code requirements.
Employee Health Screening & Exclusion Policies
LA health code mandates active health screening for diarrheal illnesses and gastrointestinal symptoms before employees begin shifts. Shigella causes watery diarrhea, abdominal cramps, and fever; any employee reporting these symptoms must be immediately excluded from food handling and restroom access areas. Establish a clear written illness policy stating that employees with diarrhea must remain excluded until symptom-free for 24 hours without medication, then cleared by a licensed healthcare provider before returning. The LA County Department of Public Health recommends notifying the health department of suspected Shigella illness in employees within 24 hours, as this triggers investigation of other exposed workers and potential customer notifications.
Temperature Control & Cross-Contamination Prevention
While Shigella is primarily a fecal-oral pathogen rather than temperature-dependent like Salmonella, proper food storage prevents cross-contamination from contaminated hands during prep. Store ready-to-eat foods (salads, sandwiches, prepared items) at 41°F or below, separated physically from raw proteins on lower shelves per LA Food Code. Implement color-coded cutting boards and utensils: green for produce, red for raw meat, yellow for poultry, blue for seafood, and white for dairy—this prevents Shigella from raw items contaminating ready-to-eat foods through shared equipment. Assign dedicated handwashing stations specifically for food prep areas; restroom handwashing must occur in separate stations to avoid cross-traffic that increases Shigella transmission risk.
