Which of the following is NOT a recognized option for flocks testing positive for Salmonella enteritidis?

• A. Divert eggs to pasteurization for life of flock
• B. Vaccination of the flock against Salmonella enteritidis
• C. Depopulate the flock
• D. Egg testing with four consecutive negative egg tests to return to production

Answer: (B)

When a flock tests positive for Salmonella enteritidis, the focus is on actions that remove or neutralize the risk to consumers and confirm the flock is no longer shedding the pathogen. Diverting eggs to pasteurization for the life of the flock safely handles products from the infected birds. Depopulating the flock eliminates the infection source. Requiring four consecutive negative egg tests before returning to production provides verification that the flock has cleared the infection before it reenters the market. Vaccination against Salmonella enteritidis, while it can reduce shedding in some settings, is not recognized as a remediation step after a positive test because it does not reliably eliminate infection and can complicate surveillance and detection.
