PRRS import risk assessment

Risk assessment: introduction of PRRS virus into Switzerland via import of boar semen from foreign countries


Contact person: Christina Nathues

Duration: start in June 2011


The project included the evaluation of importing companies and exporting boar studs involved in terms of their import practices, additional requirements and monitoring schemes. With this data, a quantitative risk assessment is conducted to determine the likelihood of a semen dose to be positive for PRRSV when imported to Switzerland, and infect a Swiss sow herd..
