Hepatitis A Outbreak Response for Food Manufacturers

Immediate Response Actions (First 24-48 Hours)

Upon detection of a potential Hepatitis A contamination, immediately halt production of affected product lines and quarantine all potentially contaminated inventory. Notify your quality assurance and regulatory compliance teams, then contact your state health department and the FDA within the required timeframe—regulations vary by state, but rapid disclosure is expected. Secure cold storage for quarantined products and document the timeline of production, including batch numbers, ingredient sources, and distribution channels. Initiate a preliminary product trace to identify upstream suppliers and downstream distribution paths, which you'll need for health department filing and recall decisions.

Health Department Coordination & Recall Decision

Work directly with your local and state health department—they will guide whether a recall is necessary and what classification level (Class I, II, or III) applies under FDA guidelines. The FDA's Hepatitis A Virus (HAV) Guidance for Industry outlines manufacturer obligations; Class I recalls pose a direct health hazard and require aggressive customer notification. Provide health officials with complete traceability data: production dates, lot codes, ingredient suppliers, and a list of all customers and distributors who received the product. Maintain a dedicated liaison for the health department and document every communication in writing. Depending on outbreak severity and epidemiological evidence, the FDA may issue a press release or safety alert, so be prepared for public scrutiny.

Staff Communication, Product Tracing & Documentation

Notify all employees involved in affected product lines about the outbreak and provide clear guidance on symptom reporting, testing protocols, and work restrictions per CDC and state health guidance. Implement robust product tracing using your distribution records to contact every customer—wholesalers, retailers, foodservice operations, and consumers—with detailed recall information and instructions for product return or disposal. Create a comprehensive incident file documenting the outbreak source investigation, corrective actions (e.g., enhanced sanitation, ingredient supplier audits, process controls), and verification that contamination was eliminated before resuming production. Retain all testing results, lab reports, supplier certifications, and communications with health authorities; these records may be subject to inspection by the FDA or state agencies for months or years following the outbreak.
