In 2018, a PRRS monitoring program started in Belgium. In this perspective, in Wallonia, where only 6% of Belgian pigs are kept, PRRS seroprevalence was assessed on both breeding and fattening pig farms. Serum samples (n = 1786 from 585 sows and 1201 piglets and/or growing pigs) collected in 2016 were tested with Elisa Idexx PRRS X3 on a maximum of 10 breeding and/or 5 feeder pigs per farm (i.e. 106 farrow-to-feeder/finish and 203 growing/finishing farms).
