Japanese encephalitis virus a focus for Swine Health Information Center
The Swine Health Information Center is ramping up efforts to prepare the U.S. pork industry for the Japanese encephalitis virus (JEV).
SHIC executive director Megan Niederwerder says JEV has been endemic in several Asian countries and expanded to Australia in 2022.
“It continues to be a risk for introduction into the U.S. It is currently not in the U.S., but we want to do everything to continue that negative status here in the U.S.”
She tells Brownfield the virus is mosquito-borne and can cause reproductive outcomes on sow farms like still births, abortions, and mummified fetuses.
“So thinking about what’s the risk of introduction of that virus, thinking about where are the sea ports or airports that may be at highest risk for potential introduction of the vector.”
Niederwerder says pork producers should consider ways to reduce mosquito populations.
“Whether that be based on the specific ventilation type of the barn, or of course when we think about standing water and reducing the mosquito cycle at all stages.”
She says SHIC board directors voted to reallocate funds to bolster Japanese encephalitis virus preparedness and prevention.
