The Keniry Report (2004) commented that the live animal export was "uniquely and inherently risky".
And it is...political disputes and standoffs, extreme climatic conditions including heat stress events, wild seas, mechanical failure, disease ....and now, piracy.
Whilst the threat of piracy has been relatively low the last couple of years, live export ships were frequently exposed to the risk between 2005 and 2012. Then there was some relief.....but the threat is now back again.
So just add piracy to that list of inherent and unique risks.
