As fall and winter approach, the Swine Health Information Center (SHIC) is advising pork producers to take a closer look at their on-farm biosecurity measures.
In its September eNewsletter, SHIC shared its latest global and domestic swine disease monitoring reports. Dr. Lisa Becton, SHIC’s Associate Director, emphasized that the seasonal transition is a critical time for producers to prepare for heightened disease risks.
“Now is the time to assess the different cleanliness in and around farms because many viruses have stability and can transmit effectively in cooler, wetter weather,” said Dr. Becton. “Everyday biosecurity practices become even more important as we head into fall and winter.”
Disease Trends Highlight Concerns
-
PRRS case positivity remained under 20% as expected for the summer months, though both Iowa and Minnesota reported levels above expectations.
-
PED case positivity stayed low overall but saw a significant increase in the wean-to-market sector, raising biosecurity concerns.
-
Influenza virus levels were below expectations, while Sapovirus diagnoses increased in tissue samples.
Dr. Becton also noted the importance of reviewing manure application practices, as manure spreading can contribute to the movement of pathogens if not handled properly.
Proactive Steps for Producers
-
Reassess all farm entry protocols
-
Review manure management procedures
-
Reinforce cleaning and disinfection practices ahead of colder months
