June Biosecurity Tip - Reducing Disease Transmission Risks during Loading

June 26, 2014 (from Ontario Pork Industry Council newsletter) Significant work has been done with respect to required wash procedures needed to reduce the risk of disease transmission associated with the transport of pigs. However, providing a biosecure method for the driver to enter a “clean” trailer has focused on using a tote containing clean boots, coveralls, gloves and a hat. If the protocol of using a tote and entering through the man door of the trailer is followed, it can result in effective disease control. But it becomes almost impossible in bad weather. It is also very difficult if the driver is physically challenged or improperly trained. If the driver inadvertently enters a “clean” trailer with contaminated footwear then all the work and cost of cleaning the trailer is potentially compromised. One solution is to devise a more functional method for drivers to enter the trailer in a biosecure fashion. Details On page two of this document is a concept drawing ...

Deadly Pig Virus Cases in U.S. Projected to Surge after Summer

June 19, 2014 (Reuters)  U.S. veterinarians are warning that outbreaks of a deadly pig virus will climb this autumn after a summertime hiatus, likely killing another 2.5 million pigs over the next 12 months and amplifying an increase in pork prices. Concerns persist about the expected jump in infections of Porcine Epidemic Diarrhea virus (PEDv) despite assurances from U.S. Agriculture Secretary Tom Vilsack on Wednesday that the nation is likely “on the other side” of the disease due to approval of the first vaccine directly available to farmers. Harrisvaccines, an Iowa-based company, developed the vaccine approved by USDA this week. But Joel Harris, head of sales and marketing, said there were uncertainties about how much the vaccine will thwart PEDv in cold weather. “There could be situations where the virus could overwhelm the immunity of the herd,” he said. The spread of PEDv, which thrives in cold and damp conditions, has slowed due to warmer temperature ...

USDA: Effects Of PEDv Outbreak Evident In U.S. Pig-Per-Litter Rate

June 17, 2014 (from Indiana Swine News) The spread of the Porcine Epidemic Diarrhea virus (PEDv) in the U.S. hog sector since the fall of 2013 has contributed to reduced market hog inventories and higher hog prices in early 2014 and forecasts for lower pork production and higher prices later in the year. PEDv is a coronavirus particularly lethal to pre-weaned piglets. The first U.S. case was formally diagnosed in May 2013 and, according to the American Association of Swine Veterinarians, the disease continued to spread through the fall of 2013, and the number of new cases accelerated early in 2014. The potential effects of PEDv on pork production are first signaled by USDA survey estimates of pigs per litter. Because of the high mortality rate of very young piglets from PEDv, the latest report showed a lower average pigs-per-litter estimate for the December 2013-February 2014 pig crop. As a result, the forecast for the December-February 2014 pig crop is down 2.8 percent compared wit ...

PEDV Impacts Disease Trends

June 9, 2014 (from National Hog Farmer) Does biosecurity have benefits beyond PEDV? It comes as no surprise that porcine epidemic diarrhea virus (PEDV) has surged to become the most common enteric disease diagnosed in porcine tissues submitted to the Iowa State University Veterinary Diagnostic Laboratory (ISUVDL).  PEDV was present in over one-third of the cases of enteric disease diagnosed in the past 12 months (Figure 1.) PEDV has spread rapidly in the U.S., particularly in the period from December 2013 through March 2014. Although losses are severe, this disease has illuminated gaps in our national, regional, local, and farm-level biosecurity programs.  Many producers and veterinarians have shored up biosecurity protocols with emphasis on consistent execution on a daily basis – doing it right ALL the time. If biosecurity really matters, might one expect changes in the trends in frequency of diagnosis of other diseases? Disclaimer: Data from a diagnostic laboratory sh ...

First Canadian Case of PED since May 9 Reported in Ontario

June 6, 2014 Since the last reported case of PED in Manitoba on May 9, Canada has gone almost a month with no further incidents. But it had to end sometime, and on June 4, it did. PED was reported on a farrow-to-finish operation in Middlesex County in Ontario. That brings the total number of cases in Ontario to 59. The disease continues to spread in the United States as well, with 142 new cases last week. There are now 7,111 confirmed cases in the U.S. involving 30 states. These developments underscore the importance of staying vigilant at all times with biosecurity practices. While PED poses no danger to humans or the food supply, it causes up to 100% mortality in nursing pigs. The virus is spread by the fecal-oral route, with the most common sources of infected feces coming onto a farm being pigs, trucks, boots, clothing, or other things that can physically move it. Make sure all incoming animals are healthy. All trucks and trailers MUST be thoroughly washed, dried and disinfecte ...

Veterinarian Confirms PEDV Can Re-infect a Previously Exposed Herd

June 5, 2014 (from National Hog Farmer) Reuters News reported on an incidence of re-infection with the porcine epidemic diarrhea virus (PEDV) on an Indiana farm this spring. Matt Ackerman, DVM, a southeastern Indiana swine veterinarian, spoke to Reuters on behalf of his clients who own the farm that experienced the re-break. Ackerman said that the same strain of PEDV hit the farm in May 2013, and again in March 2014. Jittery pork producers had been talking about rumored re-breaks throughout the winter and spring. Ackerman’s announcement is said to be the first public confirmation of a farm’s experiences with a re-infection that occurred in spite of strict biosecurity and sanitation protocols. The outbreak was not as deadly to piglets the second time around, with a 30% death rate on the second outbreak compared to 100% piglet mortality with the first PEDV infection, according to Ackerman. An American Association of Swine Veterinarians (AASV) spokesman told Reuters that PEDV outbreaks ...
