Porcine Respiratory and Reproductive Syndrome (PRRS) has had a huge
impact on pork producers in Ontario and around the world. This has
spurred researchers at the University of Guelph, led by Dr. Cate Dewey, to study
PRRS in Ontario in order to understand how it spreads, what strains are currently
here and why farms which were negative break with the disease. Their research project, sponsored by Ontario Pork, is taking a look backward
to see where the virus was in the past few years, as well as looking forward to try
and understand how it is changing and moving. Any positive blood tests taken
since September 2004 are of interest to the researchers.
