  <li>In suspect holdings without symptoms and in contact holdings, the following additional samples are taken:</li>
  <ul>
    <li>Swabs (Nose/pharyngeal swabs or Probang) from a number of animals so that a disease present at a minimum prevalence is detected with a defined level of confidence (<strong>parameters g and h</strong>),</li>
    <li>Blood samples EDTA, so that a disease present at a minimum prevalence is detected with a defined level of confidence (<strong>parameters g and h</strong>),</li>
