Cyclospora Prevention for San Francisco Food Service

San Francisco DPH Requirements & Local Regulations

The San Francisco Department of Public Health requires all food service establishments to implement Hazard Analysis and Critical Control Points (HACCP) protocols under California Health & Safety Code Section 113860 et seq. For high-risk produce like imported herbs and berries, DPH mandates supplier verification documentation, including certificates of analysis and traceability records. Operators must maintain written procedures for produce washing and storage, and DPH conducts routine inspections to verify compliance. Any suspected Cyclospora case must be reported to DPH within 24 hours; restaurants are required to cooperate with outbreak investigations and provide invoices, supplier contacts, and menu items from suspected dates.

Cyclospora Common Sources & Supplier Vetting

Cyclospora contamination primarily originates in water-rich growing regions and spreads through imported cilantro, basil, dill, parsley, raspberries, blackberries, and pre-cut salads. San Francisco food service operators should prioritize suppliers who conduct third-party pathogen testing and can provide lot-specific food safety certifications. The FDA's Produce Safety Rule (21 CFR Part 112) applies to domestic suppliers; for imported produce, verify that suppliers comply with the Foreign Supplier Verification Program (FSVP) under 21 CFR Part 256. Request Certificates of Analysis (CoA) for high-risk items, maintain traceability records linking products to specific lots and dates, and establish a recall protocol in case of contamination alerts from the FDA or your supplier.

Operational Prevention & Outbreak Response

Implement washing protocols using potable water for all produce; note that Cyclospora's oocyte stage survives standard sanitization, so prevention relies on sourcing verified, tested product. Train staff on proper cold-chain maintenance (cilantro, berries, and greens stored at 41°F or below) and time-temperature control. Segregate suspicious produce immediately and notify your DPH Environmental Health Inspector and the California Department of Food and Agriculture (CDFA) if contamination is suspected. In a confirmed outbreak scenario, cooperate with DPH's trace-back investigation, retrieve point-of-service records to identify affected customers, and prepare to issue public notices and implement voluntary recalls aligned with FDA guidance.
