treatment with a Kemin antimicrobial, such as Sal CURB, in the feed material.


The third intervention is having ‘kill’ steps within the facility in place. This is achieved with the synergistic effects of factors such as heat and a chemical treatment. The heat treatment is applied through feed mash conditioning and pelleting. The chemical treatment is the addition of Sal CURB, the antimicrobial solution. It is essential, as part of feed hygiene, that conditioning and pelleting temperatures required to kill pathogenic moulds and bacteria, such as Salmonella, are reached. Excessive temperatures may have detrimental effects on essential nutrients or bioactive compounds. Feed safety is a core value at Kemin, ensuring the Sal CURB dispersing solution is added, which kills upon contact, additionally works in synergy with heat treatment, to achieve microbial kill-off.


The fourth intervention is preventing re-contamination. This is achieved through the residual effect experienced after the application of Sal CURB. This consists of a synergistic combination of organic acids, their salts, surfactants and a corrosion inhibitor, to ensure that firstly the volatile components kill on contact and secondly the salts provide extended residual protection. The surfactants enhance the dispersibility of the Sal CURB and its active ingredients in an activated water solution, ensuring maximum dispersion and penetration within the feed matrix.


For the fifth and last intervention Kemin has developed innovative non-antibiotic solutions which work in vivo and are instrumental in protecting birds from Salmonella infections. They act by preventing or reducing intestinal carriage, ultimately decreasing the prevalence of Salmonella in breeding and commercial flocks. FormaXOL is a doubly microencapsulated product, which uses two main ingredients (functional flavours and organic acids) to control Salmonella. Studies done with FormaXOL consistently demonstrate a reduction of carriage by up to 2 log10 cfu per gram of intestinal content, as well as a reduction in the percentage of positive analyses in poultry flocks.


Effective feed safety These interventions are supported by a team of experts within our three critical Kemin services, these include the customer laboratory monitoring, application engineering technology and technical support. Our approach to controlling Salmonella is aligned with biosecurity programmes and their critical control points, measures and actions implemented at identified points. Collecting and monitoring such data, through representative sampling and data collection procedures, allows for data driven decision making. This ensures effective feed safety and animal health risk assessments and corrective actions within the monitoring programme are preventing Salmonella re-contamination throughout the value chain.

Pathogen control within the feed to food chain requires multiple interventions to be incorporated.
