Do we take biosecurity seriously?

摘要

If we look at the costs of disease, such as a Marek's disease outbreak in a broiler breeder flock that causes 20% cumulative mortality or Newcastle disease that causes a 50% egg drop, they can be very significant! However, should we look at this as acost of disease or is it really the cost of our biosecurity system failing us? The costs in these examples are high enough, but think of the costs to your company if highly pathogenic avian influenza strikes a farm or if Salmonella enteritidis percolates down your production system causing you to lose a major supermarket account!
