This study compared a novel non-formaldehyde combination product developed for pathogen control in animal feed Finio (A), with a panel of three commonly used organic acid feed additive products: Fysal (B), SalCURB K2 (C) and Salgard (D). Products were evaluated for their ability to reduce <i>Salmonella</i> Typhimurium DT104 and avian pathogenic <i>Escherichia coli</i> in poultry feed. A commercial layer-hen mash was treated with each product and then mixed with feed previously contaminated (via inoculated meat and bone meal) with either <i>Salmonella</i> or <i>E. coli</i>. After 24 h at room temperature, 10 replicate samples were taken from each preparation and plate counts were performed using a selective agar. All concentrations of product A (0.5, 1.0, 1.5, 2.0 and 2.5 kg per metric tonne (MT)) plus the higher concentration of products B and D (6.0 kg MT⁻¹) significantly reduced <i>Salmonella</i> counts compared with those in the untreated control group (<i>p</i> < 0.05). Product C did not significantly reduce levels of <i>Salmonella</i> under these conditions. Because of the poor recovery of <i>E. coli</i>, statistical comparisons for this organism were limited in scope, but only product A at the highest concentration appeared to have eliminated it.
