Salmonella Control Programme

Salmonella affects performance, animal health and food safety. In order to comply with legal and commercial standards, its prevalence needs to be minimized as early as possible in the production chain.

Selko offers customers an holistic and integrated approach focusing on feed, farm, and health aspects. The programme provides a solid basis to protect animals from Salmonella colonization reducing transmission and dissemination through the entire production chain.

A customized & integrated approach

Feed

Control Salmonella in feed is a critical step to ensure safe food

Salmonella can be easily introduced into the feed by contaminated ingredients, sub-optimal processing, and sub-hygienic transport, storage, distribution, and administration. Organic acid-based feed additives can improve feed hygiene and reduce the risk of recontamination.

Farm

Good water quality is a pre-requisite for efficient Salmonella control on the farm

Salmonella can be introduced and spread not only through feed but also through water. Reducing microbiological load in the water and preventing biofilm formation in the water lines are therefore critical.
Acidification with organic acids reduces the pH of the water and supports microbial balance in the presence or absence of chlorine.

Health

Strengthening the bird's natural defence mechanisms reduces the horizontal and vertical transmission of Salmonella

The factors that affect the ability of Salmonella to colonise are complex and diverse. An efficient Salmonella control concept looks beyond feed and/or water acidification and empowers the natural defence mechanisms in the intestinal tract of the birds.

 

Selko' Salmonella scan

Selko’s Salmonella scan focuses on sampling, serotyping, and benchmarking. It is crucial to identify critical risks and control points and the relevant Salmonella serotypes. It establishes the dynamics of the Salmonella contamination within the production chain, and provides the basis for our customized and integrated control programme. 

Feed Additives

Feed and/or water additives can complicate the colonization and invasion process of Salmonella. 

  • Preventing bacterial intake via feed & water: Low pKa short-chain fatty acids (SCFA's) (delivered via feed and/or water) strengthen the low pH barrier of the upper digestive system and the mucosal barrier in the lower intestinal tract.
  • Stabilizing the microbiota: high pKa SCFA’s and medium-chain fatty acids (MCFA’s) create a more challenging condition in the non-acidic part of the intestinal tract. Non-digestible oligosaccharides have a prebiotic effect that contribute to a more competitive microbiota. Additionally, specific oligosaccharides show a high binding affinity for Salmonella fimbriae, reducing intestinal colonization.
