You don’t know what you don’t know. And you don’t always know what your colleagues do know.

There are two categories of pseudorabies virus (PRV). Classical PRV was formerly present in North American commercial production prior to eradication in 2004. It has been eliminated in much of the developed world, but does reside in feral pigs in the US, Europe, Latin America, and Asia.
Senecavirus A (SVA or Seneca Valley Virus) infection is indistinguishable from foot-and-mouth disease (FMD) and other swine vesicular disease, so every outbreak, including at harvesting plants, must be investigated.
