The thesis deals with Salmonella control programmes in broilers and summarises the current state of knowledge on the biology, epidemiology and transmission of Salmonella spp. The introductory section outlines the aetiology, serotype diversity and pathogenesis, emphasising the role of biofilm formation and the growing problem of antibiotic resistance. In the central part, preventive and corrective measures are presented and critically evaluated, including biosecurity measures in poultry production, measures in slaughterhouses and the use of antibiotics, probiotics, prebiotics, synbiotics, postbiotics, phytobiotics, bacteriophages and vaccines. The essential role of strict biosecurity measures and vaccination (especially in breeding flocks) is emphasised, while synbiotics, postbiotics, phytobiotics and phage therapy are mentioned as promising alternatives in the context of reducing the use of antibiotics. In addition, the European Union legal framework and national legislation regulating sampling, official controls and microbiological criteria for food safety are summarised. An analysis of Slovenian data shows a low prevalence of the target serovars S. Enteritidis and S. Typhimurium in broiler flocks and an increasing importance of S. Infantis, which emphasises the need for continuous surveillance and adaptation strategies. Finally, an integrated and sustainable approach is emphasised that combines strict biosecurity, vaccination and the prudent use of natural or biological preparations while reducing the preventive use of antibiotics. Such a model minimises risks to public health, improves animal welfare and supports the economic stability of the poultry industry.
