Applying organics acids and essential oils
Regulations to control Salmonella in the animal industry are one of the major challenges. Salmonella is found everywhere and can survive, even at low moisture levels, for a long time. Animal feed is generally considered to be an important factor to control Salmonella. Due to the complexity to control Salmonella, several measurements need to be taken in parallel in the feed production: prevention of Salmonella contamination, avoid growth of Salmonella and killing of Salmonella. In many cases a combination of heat treatment and chemical treatment is used to kill bacteria. Chemical treatment normally consists of a blend of acids. A novel approach is to combine organic acids with specific essential oils. Results have shown that such a combination is more effective in killing Salmonella.
