Switzerland tightens biosecurity rules for pig farms

Switzerland is raising the biosecurity threshold for every pig holding in the country. The Federal Food Safety and Veterinary Office has introduced new requirements designed to reduce the risk of African swine fever, a disease that can devastate domestic and wild pig populations and disrupt livestock markets.

The rules apply across the sector, from commercial breeding and fattening operations to small hobby farms. The first stage, known as Level 1, covers normal operations and focuses on preventing the virus from entering a holding. Farmers must control access, establish hygiene barriers and limit contact between domestic pigs and wild boar. They must also keep detailed records, including information on visitors and animal deaths.

The timing reflects a changing disease picture in Europe. The federal government assessed the risk of African swine fever entering Switzerland as high this summer. Italy reported cases in domestic pigs for the first time in April 2026, after the number of European cases had declined for several years.

The FSVO developed the requirements with the pig industry. Compliance will give farms a recognised status that can affect how they operate if the disease reaches nearby holdings or regions.

Access control becomes the first line of defence under Level 1. Pig farms must manage who enters their premises and introduce hygiene barriers that reduce the chance of carrying the virus on clothing, footwear, vehicles or equipment. The measures are intended to interrupt transmission before it reaches the animals.

The rules also target one of the most important routes for African swine fever: contact between farmed pigs and infected wild boar. Holdings must take steps to prevent physical contact and reduce opportunities for wild animals to approach domestic pigs. The source material does not specify a single national design for fencing or farm layouts, leaving implementation to the conditions of individual holdings and oversight by veterinary services.

Record-keeping is another central requirement. Farmers must document visitors and deaths, creating a traceable account of activity on the farm. That information can help authorities investigate suspected transmission and respond more quickly when disease is detected.

The system covers farms of very different sizes. A hobby holding therefore faces the same national biosecurity framework as a professional operation, although the practical arrangements may differ. The FSVO says the requirements were drawn up in collaboration with the industry, signalling an attempt to align enforcement with daily farming conditions.

Compliance will be checked repeatedly, not certified once and forgotten. A health service provider will carry out an initial inspection of each participating farm, followed by two visits every year. The monitoring is intended to verify that the required controls remain in place during routine operations.

That schedule gives the new status practical consequences for farmers. Access systems, hygiene barriers and records must function over time, including during busy periods, staff changes and animal movements. Farms will need to show that their procedures operate consistently rather than simply preparing for an inspection.

The FSVO has linked compliance to advantages during a local outbreak. Farms with the status may receive more relaxed rules governing the movement of animals and the marketing of livestock if African swine fever is detected nearby. The precise measures would depend on the outbreak situation and the authorities’ assessment, but the incentive is clear: stronger prevention can preserve more operational flexibility when restrictions are imposed.

The arrangement also creates a formal connection between farms, health service providers and government veterinary authorities. If conditions worsen, that network can support faster information sharing and targeted action across Switzerland’s cantons.

A second stage is already planned for an outbreak. If African swine fever reaches Switzerland, the biosecurity framework would expand beyond routine prevention. Additional requirements would cover animal movements and diagnostic investigations, with cantonal veterinary offices responsible for monitoring those measures.

The staged approach allows the authorities to distinguish between normal farm operations and emergency controls. Level 1 applies now, before an outbreak, and asks farms to build basic barriers against introduction. The second stage would operate in a more pressured environment, when authorities need to trace possible infections, limit spread and decide which animals or products can move.

The need for preparation is tied to developments beyond Switzerland’s borders. The FSVO has warned that transmission to domestic pigs is possible at any time in regions where wild boar carry the disease. Switzerland’s geography and trading links make cross-border surveillance important, while the presence of wild boar creates a domestic pathway that farms cannot ignore.

For Swiss producers, the immediate task is practical: establish access controls, maintain hygiene procedures and keep reliable records. For cantonal authorities, the new system sets a common national baseline. Its effectiveness will depend on how consistently farms apply the rules and how quickly officials can act when a suspected case emerges.
