PRRS and PED outbreaks down substantially in last year

Swine health monitoring needs to continue as this will provide an important benchmarking tool from an infectious disease standpoint.

Swine infectious diseases continue to represent one of the main challenges in swine production around the world. Unfortunately, there are diseases that become a recurrent problem as transmission and dissemination continues, leading to substantial economic losses.


Porcine reproductive and respiratory syndrome virus and porcine epidemic diarrhea virus are two important pathogens that cause major pig flow disruptions. These two diseases also drive a great degree of uncertainty within the industry, every year the industry wonders how these two viruses will behave and whether the present year will be worse or better than previous years.


Today we are in a better position in understanding these diseases through a Swine Health Information Center-funded voluntary program called the Morrison Swine Health Monitoring Project. During the last 12 months there has been a change in disease occurrence as fewer breeding herd outbreaks have been reported in our industry.


PRRSV has been infecting an average of 28.7% of the participating herds in the last decade. However, during the 2018-19 MSHMP year beginning in July and with a few weeks remaining to close the year there has been a change as a total of 19.9% year-to-date of the herds have reported an outbreak (Table 1). Compared to the previous year (e.g. 34.2%), this is an important reduction as a level that low had only been seen during the 2013-14 year, the same year when PEDV emerged in the U.S. industry.


Additionally, the occurrence of PEDV during 2018-19 has also changed. After the emergence and nationwide outbreak of this virus which infected more than half of the herds in the project, the virus occurrence remained close to 10%. However, in this current MSHMP year there is a significant decrease in PEDV as the proportion of herds having an outbreak decreased to below 5%. In both cases, having a fewer number of outbreaks indicates less disruptions in breeding-herd throughput and healthier pigs coming out of the door.


Changes in disease trends are important to document and understand. Fortunately, through the MSHMP, these have been captured. With these viruses behaving differently, it warrants the question of what has the industry done in order to influence transmission and dissemination. Most likely, biosecurity measures are playing a role as this is the first line of defense when dealing with infectious diseases, not only at the animal but also human level.


Interestingly in 2013-14 when PEDV emerged in the United States...

Virus Threatening Pigs Throughout The Southeast

07 June 2019


Hog companies in the southeast are experiencing an outbreak of PED.


That, according to Pro-Vista Co-Owner Arthur Rempel who says three of his farms have been infected by the virus in the past two weeks.


“It tends to be that when a barn breaks with this disease the entire barn will be infected very quickly,” states Rempel. “On our farms that are affected, the entire populations are infected.”


PED, or Porcine Epidemic Diarrhea virus, infects the cells of a pig's small intestines and causes severe diarrhea and dehydration. Rempel indicates that this illness will be particularly devastating among piglets under 15 days old. He says most of those infected will die.


“A lot of effort and energy is put into raising good quality animals," comments Rempel, "and when they are so compromised by their health it is virtually a complete loss for a number of weeks.”


Rempel acknowledges that his company, along with others in the region, will likely endure a significant financial loss because of this gap in production.


Though PED is harmful, it is not altogether uncommon and Rempel says local hog companies battled another difficult strand of the virus a couple of years ago. Throughout his time in the industry, he has come to realize that the situation should improve fairly quickly...





PED Virus Moves West Of The Red River

Manitoba Pork has now confirmed 21 cases of the porcine epidemic diarrhea virus (PED) in 2019, which include 10 sow, 2 nursery, and 9 finisher operations.


Nineteen of those are in southeast Manitoba and two west of the Red River in the Lowe Farm/Morris area. Manager of Swine Health Program Jenelle Hamblin says there were cases west of the Red River back in 2017. Those cases were traced to direct animal movement, however the 2019 cases (both sow operations) did not have any direct animal movement and really no identifiable contacts to any previously infected farms in the southeast.


"It's definitely concerning," said Hamblin. "We've done a lot of surveillance testing in the area, as we have done in the southeast as well, making sure that we can catch it if it is moving...I know that the farms in that area are being hyper-diligent with keeping an eye out for potential signs."


Manitoba Pork is strongly recommending that producers ramp up their biosecurity efforts.
