Según las investigaciones, el virus puede sobrevivir por períodos extensos en varios medios utilizados en la producción de alimentos para cerdos. Son factores de riesgo a considerar en la diseminacón de la enfermedad. Saludos, Maria Irian

Research details lifespan of PED virus in feed grains

Porcine Epidemic Diarrhea (PED) has been a devastating disease to the swine industry, resulting in the loss of more than 8 million piglets. In an effort to reduce the risk to Pipestone sow units, Pipestone Applied Research was the first in the world to prove that contaminated feed could serve as a vehicle for PED virus (PEDv) transmission. As a follow up, Pipestone’s newest study focused on how PEDv survives in individual feed ingredients in order to focus intervention efforts and further reduce risk.

Key takeaways from the project:

- Ingredients tested include corn, soybean meal, DDGs, several porcine by-products, vitamin/trace minerals, fats, synthetic amino acids, limestone and choline. In approximately 50 percent of these ingredients, the virus was able to survive for extended periods. However, in other ingredients, it was not able to survive for even a day.
- Specifically, live virus was recovered from soybean meal for 180 days, from complete feed for 45 days, and from DDGS, choline, amino acids and choice white grease for 30 days, respectively. In contrast, live virus was not detected in porcine plasma at day 1.
- Application of a liquid antimicrobial (SalCURB) successfully neutralized virus, independent of ingredient type.
    The Pipestone team is determining how to manage these newly discovered risk factors.
