Abstract
Purpose of Review Ensuring broilers’ meat safety is a priority to policy makers, producers, and consumers. This systematic
review aims to update the recent knowledge on pre-harvest interventions to control main foodborne pathogens in broilers and to
assess their effectiveness.
Recent Findings A total of 815 studies were retrieved from PubMed® andWeb of Science for 13 pathogens. In total, 51 studies
regarding Campylobacter spp., Salmonella spp., VTEC, ESBL-AmpC Escherichia coli, and Clostridium perfringens were
included in this review.
Summary Research mostly focused on Salmonella spp. and Campylobacter spp. Biosecurity and management interventions had
mixed outcomes, while the effectiveness of feed additives, though intensively researched, remains controversial. Research on
other pathogens (i.e. ESBL-AmpC E. coli/Salmonella, and Toxoplasma gondii) was scarce, with publications focusing on
epidemiology and/or on source-attribution studies. This is also true regarding research on Listeria monocytogenes, Bacillus
cereus, Clostridium botulinum, Clostridium perfringens, and Staphylococcus aureus as these are frequently controlled by
post-harvest interventions. Overall, studies on recent developments of novel pathogen-specific immunisation strategies are
lacking.
