Salmonella and Its Impact on the Poultry Industry
The article examines Salmonella infections in poultry, highlighting their significant impact on bird health, productivity, and food safety. The main diseases discussed are Pullorum disease, Fowl Typhoid, and Paratyphoid, with emphasis on their symptoms, lesions, transmission routes, and effects on young and adult birds.

Salmonella can spread through contaminated eggs, hatcheries, feed and water, equipment, rodents, insects, wild birds, visitors, vehicles, and animal protein sources. The article stresses that strict biosecurity is the most effective defense, including proper sanitation, egg handling, hatchery hygiene, pest control, visitor restrictions, and safe disposal of infected birds and waste.
The article also discusses antibiotic treatment as a means of reducing bacterial levels and clinical effects, while noting that treated birds may remain carriers. Overall, it emphasizes that Salmonella control requires an integrated prevention and biosecurity program covering the entire poultry production chain.
