Antimicrobial-resistant Salmonella poses a severe threat to food safety and public health, particularly through persistent biofilms on food-processing surfaces and animal-derived products. Traditional disinfection methods often fail against biofilms, while antibiotic overuse accelerates resistance. Bacteriophages offer a targeted, sustainable alternative, but their real-world efficacy in food systems remains underexplored. This study addresses critical gaps by evaluating a novel phage's p
