(I spent 2007 as a biosecurity researcher focused on H5N1. Corporate meat production is one seriously surreal logistics problem, ethics and health issues aside. My breaking point was sitting through a presentation on a miraculous new orange scented foam that could be sprayed into an infected chicken house to simultaneously smother the birds, disinfect the premises and compost the bodies. The inventor of said foam kept emphasizing how it was orange scented, it would be acceptable to the public!)
I have seen said foam in action (wasn't orange scented) and it is remarkably effective in a very disturbing way. The presentations that I saw focused on the ability to quickly and effectively depopulate with minimal human exposure. This was in the context of H5N1 and the veterinary/public health interface. And as you mentioned - it is a major logistical problem.
