If a flock testing positive for Salmonella enteritidis engages in egg testing and one of the four consecutive samples tests positive again, what action is required?

• A. Divert eggs for pasteurization for the life of the flock
• B. Depopulate the flock
• C. Return to normal production with one positive test
• D. Increase sampling frequency but no divert

Answer: (A)

When a laying flock tests positive for Salmonella enteritidis and egg testing shows repeated positive results, the priority is to prevent contaminated eggs from reaching consumers. In this situation, the eggs from that flock must be diverted for pasteurization for the life of the flock. Pasteurization inactivates Salmonella in eggs, dramatically reducing the risk of foodborne illness while allowing eggs from the flock to remain in the supply chain under safety measures. A return to normal production without pasteurization would maintain a consumer health risk, and while depopulation is a potential ultimate action in some scenarios, the mandated response here is ongoing diversion for pasteurization. Increasing sampling alone does not remove the public health risk, so diversion to pasteurization is the appropriate and safer course.
