By May 2023, 85% of all Danish pig herds have a serological PRRS status. Area eradication programs have been established in regions with a high density of PRRS seropositive herds. The Danish Agriculture & Food Council has taken a range of initiatives with the purpose of paving the road for a national reduction of PRRS, including an implementation strategy, digital tools, common guidelines for the classification, monitoring, and eradication of PRRSV, and project funding resources.

Here we will focus the discussion on the practical applications and on lessons learned from recent field studies on response strategies for PRRSV management in affected breeding herds.

The collection of tongues from stillborn piglets as a system to monitor the stability at farrowing serves to improve PRRS virus detection.

Consider these factors when deciding to eliminate or control PRRSv.

The goal is set in Danish pig production - By 2025, 75% of all finishers will be PRRS seronegative at slaughter. This will be achieved by a close corporation between veterinary authorities, the pig industry, slaughter companies, veterinarians and producers.

The Hungarian PRRS eradication program is based on a territorial approach as it is the only approach by which the infection or reinfection of PRRSV-free pig herds can be avoided with high probability.

With more herds breaking with highly virulent PRRS strains, what can we do to prevent and control infection? How does the 1-4-4 L1C strain differ?

This PRRSV strain is affecting the U.S. Understanding where these viruses come from can help us stop this cycle.

Do we know what percent of imported batches of pigs are viremic for PRRS and to which strains?
