This practical extension article out of Canada insightfully explains how farm workers learn about biosecurity.  In a nutshell they do most of their learning while on the job and through observing the positive, and negative behaviours of their managers, peers and mentors.  It goes on to point out that knowing how good biosecurity practice influences overall business performance provides many with the context and incentive to routinely practice good biosecurity behaviours.

So… ‘do what I do not what I say’ seems a good adage to follow for owners, managers and others that seek to positively influence biosecurity outcomes.
