Updated advice for quarantining offers gold-silver-bronze options

Experts in risk management say a 'risk' is something that can be quantified and/or the probability calculated, so we canmake a balanced decision. For example, few of us would risk a tightrope walk but happily ride a bike.When we can't assess the risk it is described as an 'uncertainty' which leaves us less able, and therefore less willing, to make a decision. Is our inability to quantify the risk the reason why, as an industry, we find it so difficult to spend time and money protecting our flocks from threats brought by in-coming sheep?
