Salmonella spp. contaminates egg and poultry meat leading to foodborne infections in humans. The emergence of antimicrobial-resistant strains limit the use of antimicrobials. We aimed to determine the effects of the food supplement, fermented defatted ‘alperujo’, a modified olive-oil by-product, on Salmonella Typhimurium colonisation in broilers. One hundred and twenty 1-day-old broilers were divided into four experimental groups: 2 control groups and 2 treated groups, and challenged with S. Typhimurium at day 7 or 21. On days 7, 14, 21, 28, 35 and 42 of life, duodenum and caecum tissue samples were collected for histopathological and histomorphometric studies. Additionally, cecum content was collected for Salmonella spp. detection by culture and qPCR, and for metagenomic analysis. Our results showed a significant reduction of Salmonella spp. in the cecum of 42-day-old broilers, suggesting that fermented defatted ‘alperujo’ stimulates Salmonella Typhimurium clearance in that cecum and may contribute to diminishing the risk of carcass contamination at the time of slaughter. Additionally, the improvement of the mucosal integrity suggests that enhancing intestinal health helps to limit Salmonella spp. colonisation in the host, mitigating production losses. These results could provide evidence that FDA would contribute to prophylactic and therapeutic measures to reduce salmonellosis prevalence in poultry farms
