Campylobacter spreads mainly horizontally. However, it remains viable for a short time in the environment; therefore, proper cleaning and disinfection between flocks is essential to avoid transmission between flocks.
The main problem lies in the high concentrations of the microorganism in the cecum upon arrival at the slaughterhouse. For this reason, we must control their presence in caeca during rearing, primarily through high-quality microbiological chlorinated water and feed additives (such as acids), since, in the absence of another effective immune tool, it is the only thing we can do.
In addition, we have to be especially careful in the fasting stage and transport to the slaughterhouse. Reducing time and stress to the maximum and preventing microorganisms entrance through transport personnel. All these facts must be controlled to avoid, as far as possible, the arrival of animals at the slaughterhouse, excreting the bacteria in faeces since it would be a great danger for external contamination of the carcass.
