Biosecurity and control of epidemics
Enric Marco, Swine consultant, Marco Vetgrup, SLP (Spain)
Covid-19 infection force all of us to take measures to prevent the infection, but also to prevent it to be spread. Masks, cleaning hands, social distancing… All these measures are what is known as biosecurity.
Farm biosecurity include the application of health controls and measures to:
- Prevent the introduction of new infectious diseases into herds.
- Contain the spread of other infections already present in the farm.
10 measures to avoid introduction of a new infection
Ideally located out-side the main farm.
Allows to define clean and dirty zones and it should prevent the re-entry of animals and liquids.
Complete fence surrounding the whole farm:
In order to prevent the entry of animals and people.
A sign reading “No entry for health reasons” should be erected plus a system to notify the arrival.
Situated within the main perimeter fence. After the showers or an intermediate area (e.g. Danish SPF herds) overalls, farm shoes or boots and hat should be provided.
The entry of pork or its by-products should be banned.
Feed should be loaded from outside the fencing.
Slurry’s pit should be located outside the fence.
It can allow to disinfect and isolate materials for a while before moving them inside.
Incinerator/Collecting point for dead animals:
It must be fenced and located outside the main perimeter fence but attached to it to allow disposing carcasses from clean side.
5 measures to avoid the spread of infection inside the farm
Batch management and batch integrity
Avoid: rolling back animals, workers moving among batches form old to young, not changing needles when injecting…
Fly and rodent control:
Combined with a good cleaning and disinfection program.
Aspects such as feed, water, climate, density and welfare are of vital importance.
The ideal complement to the previous measures.
