PED 예방 요령 - Steps To Preventing PEDv in Your Farm

 

Porcine Epidemic Diarrhea Virus

 

Steps To Preventing PEDv in Your Farm

 

The spread of porcine epidemic diarrhea virus (PEDV) since May 2013 has caused the U.S. swine industry to re-evaluate biosecurity of our farms. The main goal of a biosecurity program should be to block the entrance of microorganisms that cause disease, a term known as “bio-exclusion.”
 
PEDV is transmitted via the fecal-oral route and can remain infectious for several days; therefore, any surface that could have been contaminated with manure from infected pigs represents risk. With that in mind, what are some risk factors and bio-exclusion practices that farms need to consider before cooler weather and greater risk of PEDV introduction arrive?
 
  • Introduction of pigs: all receiving farms should have definitive isolation, diagnostic testing and clinical observation for their incoming breeding stock animals.
 
  • Manure handling and application to fields: assume that all equipment and people are contaminated; therefore, avoid contact with your pigs.
 
  • Animal feed: recent research (Dee, et al, 2014) has provided proof of concept of feed being a risk for introduction of PEDV into farms. Multiple feed handling/manufacturing practices are being evaluated including chemical treatment, avoiding animal-origin ingredients and modifying people/vehicles traffic to minimize risk of contamination. For feed risk reduction strategies specific to your operation, consult your veterinarian or nutritionist.
 
  • Transportation of pigs: trailer, truck, driver, load chutes and equipment used for movement of swine should be considered. Anything that can be contaminated with fecal material must be cleaned, disinfected and dried.
 
  • People, equipment and supplies onto the farm: assume that every object entering the farm is contaminated. Define clear clean and dirty lines and follow the decontamination protocols recommended by your herd veterinarian.
 
  • Disposal of mortality: rendering is discouraged because the risk of transmission between farms visited by the same vehicle. Composting, incineration or burial have lower risk.
