The transmission of PEDV through the feed supply chain is an example of a complex disease transmission pathway that triggered swine feed industry stakeholders to collaborate in understanding and addressing the risk factors.

The article suggests measuring external risks in order to compare swine farms based on a numerical figure, and thus initiate corrective measures to improve and numerically verify the improvements achieved.

All sequenced PEDV isolates that were found recently within European countries were most closely related to so called S INDEL PEDV, which was originally described in the US in January 2014.

This type of investment may not be crazy when it comes to protecting farms with high genetic value (others are dependent on) or insemination centres.

Pigs can act as a source of new influenza strains with zoonotic potential, but the increase of the genetic diversity of the swine influenza viruses is largely due to the introduction of influenza strains of human origin. Therefore, it is highly recommended that all staff that has frequent contact with pigs should be vaccinated against influenza.

Flies are not usually seen as a real risk of infection between farms unless we're talking about very high-density areas. However, flies can travel long distances if captured when collecting carcasses.

The author questions whether the US virus is more virulent than the strain CV777 isolated in Europe in 1977 or whether the disease is indeed more devastating now than it was in the seventies in Europe.

The most direct strategy to decrease the concentration in the air of airborne pathogens is dust reduction. This article describes the use of a particle ionization system called EPI.

Biosecurity measures for visitors should be implemented in all farms without exception, and hand washing with soap and subsequent disinfection should be compulsory in those farms where showering is not.

How can we tell whether a transport vehicle is clean by just taking a glimpse?

Many swine production units in North America have incorporated fumigation rooms into their barn design.

Surrounding holdings with high hedge fences reduces the risk of airborne transmission.

Today, nearly all genetic suppliers of replacement breeding stock in North America are free of M.hyo.

A simple system that uses plastic and adhesive tape to prevent the entry of unfiltered air into a barn can also serve as a safe method to prevent inappropriate non-biosecure personnel movement.

The installation of physical barriers at strategic personnel entry points help to define distinct biosecurity areas. This method is commonly used in farms that lack a clear separation between areas with different biosecurity levels.

In this second part the actions described are the ones needed when the disease is already in the country.
