Which statement is NOT a recommended control or prevention measure for Salmonella in poultry?

• A. Vaccination for specific serovars; management of carriers and environment; isolate clinically infected animals.
• B. Routine antibiotic prophylaxis in all birds.
• C. Isolation of clinically infected animals.
• D. Good management of carriers and environment.

Answer: (B)

Managing Salmonella in poultry hinges on targeted, non-antibiotic control measures alongside good biosecurity. Vaccination is used for some serovars to reduce colonization and shedding, isolating clinically infected birds helps prevent spread, and careful management of carriers and the environment (biosecurity, sanitation, litter and facility cleanliness) reduces contamination and transmission.

Routine antibiotic prophylaxis in all birds is not recommended because it promotes antimicrobial resistance and can select for resistant Salmonella strains, undermining both animal and public health. Antibiotics should be used under veterinary guidance for specific, justified cases rather than as blanket preventive treatment.
