Second post on the subject. Check it here.
In this post, several experts cover the critical subject of PRRS virus eradication on swine farms. As authorities in their respective fields, they share their experience in preventing the spread of PRRSV within and between farms and the feasibility of eradicating this virus in large swine populations.
Porcine reproductive and respiratory syndrome (PRRS) is an economically significant disease of swine that has been estimated to cost the US and EU industry approximately $664 million a year and €100 per sow. Whilst the industry has made great strides in identifying, characterizing, and diagnosing the PRRS virus in the past few years, unfortunately there is still a lack of adequate knowledge on its epidemiology in swine to allow us to be sure how to proceed with an eradication program once a herd is infected.
We asked several PRRS experts what they think about eradication of PRRSV from swine farms: watch the video.
Scott Dee – International Research Veterinarian, Pipestone Veterinary Clinic, USA.
“I think that’s a very important goal, it’s a long term goal. It’s possible at the individual farm level but it’s very difficult on the regional area level because of the way the virus can be spread. Transmitted through the air for example.”
Carlos Lasagna – Grupo Martini Pig Health Director, Italy.
“When we talk about PRRS eradication I think that is something let’s say possible, not easy but possible. However, what we have to consider in a country like Italy is the possibility that we might get the infection a second time after the eradication.”
Luc Defresne – Seaboard farms Pig Health Director, USA.
“Eradication always remains the ultimate goal and nobody is against virtue. However, I do not think that right now we have the tools to be able to expand it to a country-wide goal”.
Darwin Reicks – Swine Veterinary Center Minnesota, USA.
“Eradication of PRRS virus has been difficult and, in some cases, also challenging. We feel it is very important when a virus gets into the farm to do an eradication as soon as possible to get back to negative pig flock.”
Albert Rovira – Veterinary Diagnostic Laboratory University of Minnesota, USA.
“We’ve become a lot better in figuring out how to eradicate personal firms and how to keep farms negative from PRRS. Now we have to figure out how to do that for regions and keep moving forward. It might not work for every region and definitely in very dense areas it is a challenge”.
Albert Finestra – Independent Spanish Consultant, Spain: “Thinking about PRRS control on an isolated farm is not difficult. But if you are speaking in a highly populated area like this, it is quite difficult because all neighbours need to work together. Need to vaccinate together, need to implement the same control program. In such a situation, it is not easy to fight against this disease”.
Elisabeth Grosse – Professor, University of Veterinary Medicine Hannover, Germany. “National eradication programs, mandatory for every producer, may be effective but we need to think about the consequences in advance. And to answer those questions we need to realize that the stamping out is the only method, at least today, we have to maintain the farms free from PRRS. We need to clarify whether pig producers as well as society will accept the stamping out policy”.
