Documenting Biosecurity in Pig Farming

The basic principle is the separation of a clean and an unclean area, often described as black and white. The line between them is not merely imagined, it is built and walked: changing room, change of boots, hand hygiene, an airlock that cannot be bypassed. Where the line blurs, the best records no longer help.

Then there are the routes along which pathogens enter without people. Feed and bedding are such routes when they are stored unprotected and wild boar or rodents can reach them. Vehicles, equipment and visitors belong in the same list, and each of these routes has a rule that can be kept or broken.

The requirements rise with herd size, and above certain thresholds additional structural and organisational duties apply. Which threshold applies to you is set out in the ordinance – this article deliberately does not name it, because it can change.

The risk assessment is not a form you fill in once and file away. It walks through the farm along the routes of entry and records how things looked at the time of the assessment – access, airlock, storage, cleaning, the handling of purchased animals. From that comes a rating that the farm should not talk up, because it shows where to start.

Farms change, so the assessment ages. A new barn, a different feeding place, a change of staff – any of these can flip an answer. That is why a new assessment belongs beside the old one and not in its place: the sequence shows whether anything improved, and that is exactly what an authority wants to see.

Rising mortality is often the first visible sign of an outbreak, long before anyone voices a suspicion. That is why the figures are recorded weekly rather than added up at the end of the year, and why piglets and older animals are counted separately – a rise among suckling piglets means something different from a rise in the finishing unit.

The number alone says little; it becomes a signal only in relation to the herd and in comparison with the preceding weeks. Keeping it per production unit also shows where in the farm something is happening. That is the real purpose of the report – it lets the authority spot an event earlier than any single observation could.

Dead animals are animal by-products and belong in carcass disposal, not on the muck heap and not in a pit. The collection itself has to be documented: who handed the animal over, when it died, when it was collected, which plant took it and under which certificate number.

Storage until collection is part of this. A carcass lying in the open where wild boar can reach it is precisely the route of entry that all the biosecurity is meant to prevent. The collection point therefore belongs at the edge of the farm, with access for the collection vehicle that does not lead through the clean area.

A suspected case turns fast and formal. What is asked for then is the herd, the mortality of recent weeks, the animal movements, the visitors and the risk assessment – immediately, not after a week of searching. Anyone who first has to assemble these figures loses the resource that is most expensive in an outbreak.

So the best moment for order is the one when nothing is happening. Every record that arises alongside daily work is already finished when it matters – and the order reverses: instead of the authority waiting for you, you present what it came to see.
