This is a completely new idea brought to light by Dr. Dee here today.   

Next generation biosecurity is the application of science-based  protocols across mechanical risk, aerosol risk and feed risk at the  level of the sow farm. We need to challenge the industry to advance to  this next level. Many farms simply focus on mechanical risks and ignore  air and feed. We also need to introduce the idea of “First generation  biosecurity” as it pertains to the WTF segment.

 Basics of this topic: 

Routes of pathogen transmission can be divided into: Direct routes: pigs and seen 

Indirect routes: mechanical (transport, fomites, personnel, etc),  aerosol, feed
