Five dust samples shall be gathered using five dry sterile swabs of about 500 cm² each from five of the 10 pens selected for sampling under part A. These five pens shall be chosen in a way that breeding pigs in different production stages are included. For each pen dorsal surfaces of pen partition walls shall be swabbed. In case there is not enough dust present, then ventilator ducts etc. shall be sampled in addition. After use, the soiled swab shall be placed in a sterile plastic bag.
