SVA broke out in Brazil and saw the virus in farm feed


The outbreak of Seneca Valley A (SVA) in Brazil has targeted the disease in feed, feed ingredients and several animal facilities.

The Iowa Pig Health Information Center (SHIC) announced last week that Seneca Valley A (SVA) broke out in Brazil. SHIC said the disease was found in pigs of all ages, but the initial case was in finishing pigs.

The center said that the disease broke out in Brazil in the autumn and winter of 2014 to 2015, after the disease occurred in the United States in 2015.

Paul Sundberg, executive director of SHIC, said the center is trying to understand the risks posed by the Brazilian epidemic.

“What we know is that SVA will be able to survive in Brazil from soymeal and other feed ingredients,” he told us. “We will continue to work to obtain enough data to quantify the risks.”

SVA is one of several diseases in which SHIC has the potential to detect transport conditions in feed and feed ingredients.

The SHIC research project tracks the possibility of disease in the feed and maintains its infectivity. The initial study examined the potential of the porcine epidemic diarrhea (PED) virus in importing feed from Asia, feed ingredients and more.

Outbreak overview and feed testing

According to SHIC, the new outbreak of animal disease in Brazil's SVA is severe and the healing process is delayed. In some places, the mortality rate of pups is close to 30%.

The center said the disease was initially reported in the pig's finishing facility before it was discovered at the nursery and delivery site. However, it is also located in feed mill supplies and feed ingredients, including mixed meat and bone meal and cardamom. It was also identified as a feed for fattening pigs.

The center said it is working to compare the current disease with a strain from Brazil in 2014-15. However, it is feared that the disease is a mutant strain with increased pathogenicity.

PEDV in Canada

In another disease-related aspect, the porcine epidemic diarrhea virus (PEDv) was diagnosed in Alberta, Canada. Previously, the disease has not been reported in the province.

According to a statement from the Alberta Pork Company, animals in 400 pig facilities in Alberta have been infected.

According to the organization, Alberta pork and Alberta agriculture and forests are investigating the epidemic and taking steps to prevent the spread of the disease.

However, because PEDV does not pose a threat to human health, disease outbreaks do not cause food safety problems, Alberta Pork said.

The Canadian Food Inspection Agency (CFIA) confirmed the first reported case of the disease in a factory in Ontario in 2014. After the initial discovery, PEDV was also discovered in Quebec, Prince Edward Island and Manitoba.
