USDA Reports First H5N1 Detection in Swine

Wed, 30 Oct 2024 19:05:00 GMT

USDA announced on Oct. 30 the first reported case of H5N1 in a pig in an Oregon backyard farm. It’s important to note there is no concern about the safety of the nation’s pork supply as a result of this finding, USDA said. This farm is a non-commercial operation, and the animals were not intended for the commercial food supply.

“The confirmed case in Oregon poses no threat to consumer health or food safety; properly handled and cooked pork products remain safe for consumption,” Bryan Humphreys, National Pork Producers Council (NPPC) CEO said in a statement. “The entire pork industry remains committed to safeguarding food safety and human and animal health.”

The case was discovered on a backyard farm that includes a mix of poultry and livestock, including swine. The Oregon Department of Agriculture announced on Friday, Oct. 25, that poultry on this farm represented the first H5N1 detection in Crook County, Oregon. On Tuesday, Oct. 29, the USDA National Veterinary Services Laboratories also confirmed one of the farm’s five pigs to be infected with H5N1, marking the first detection of H5N1 in swine in the U.S., USDA reports.  

“The livestock and poultry on this farm shared water sources, housing, and equipment; in other states, this combination has enabled transmission between species. Although the swine did not display signs of illness, the Oregon Department of Health and USDA tested the five swine for H5N1 out of an abundance of caution and because of the presence of H5N1 in other animals on the premises,” USDA wrote.

The swine were euthanized to facilitate additional diagnostic analysis. Although test results were negative for two of the pigs, and test results are still pending for two others.  
The farm has been quarantined to prevent further spread of the virus. Other animals on the farm include sheep and goats that remain under surveillance.  

“USDA’s National Veterinary Services Laboratories (NVSL) has conducted genomic sequencing of virus from the poultry infected on this farm, and that sequencing has not identified any changes to the H5N1 virus that would suggest to USDA and CDC that it is more transmissible to humans, indicating that the current risk to the public remains low,” USDA wrote.

H5N1 detections include viral genome sequencing to provide additional information of interest to medical professionals and the research community to improve understanding of the virus. Genetic sequencing for these samples is underway, but results may be inconclusive due to low viral levels in the samples, USDA said.   

Pork Producers Practice Biosecurity to Protect Pigs
Biosecurity is critical to eradicating H5N1 and other viruses. Not only does biosecurity protect the health of livestock, but it also protects the health of farmworkers and their families. For more information on protecting farmworkers, visit the CDC’s website .

The pork industry has worked alongside USDA’s Animal and Plant Health Inspection Service (APHIS) since 2009 to carry out the swine influenza surveillance program to identify influenza viruses circulating in swine, proactively detect reassortment viruses that could impact public health, and gain knowledge to contribute to improved animal health diagnostics and vaccines, NPPC pointed out in a statement.

“Pork producers have always been proactive and diligent about implementing biosecurity plans as part of their daily production practices to assure animals wellbeing and food safety,” Lori Stevermer, NPPC president and Minnesota pork producer said. “This detection serves as a reminder for producers of all sizes to understand and address influenza virus risks.”

What’s Next?
USDA recently approved two vaccine field safety trials for vaccine candidates designed to protect dairy cows from H5N1, and continues to explore vaccine options for other species.   As USDA takes additional steps to protect the health of livestock, it will continue to work closely with CDC to protect the health of people and FDA to protect the safety of the food supply.

“These collective, collaborative efforts have helped protect farmworkers and farmers, the health and welfare of livestock animals, and reaffirmed the safety of the nation’s food supply. The U.S. government remains committed to addressing this situation with urgency,” USDA said.

K-State is Now On a Mission to Estimate the Potential Economic Losses From Possible Foreign Animal Diseases

Thu, 26 Oct 2023 17:32:07 GMT

Nestled in the Flint Hills of Kansas is the town of Manhattan, home to Kansas State University. Take a drive across Kansas State University today, and signs of a major focus on biodefense, and animal agriculture specifically, are everywhere.

“We have NBAF here, which is the National Bio Agro-Defense Facility , that’s on the edge of campus. So, K-State really is right in the middle of the animal health industry,” says Dustin Pendell, director of the collaborating center for the economics of animal health Americas region, K-State University.

Pendell received some exciting news this summer: K-State had been chosen to lead a five-year global animal health effort, by opening a new center. Called the Collaborating Center for the Economics of Animal Health, Americas Region , the K-State University professor and economist already had some ambitious goals.

“In a decade from now, I hope that anywhere across the world, if anybody needs anything done related to economics for animal health, animal burdens or animal welfare, they immediately turn to K-State,” he says.

Starting to Assemble the Building Blocks

Pendell and team are just starting on the building blocks, ones that will develop decision-making tools and improve communication on the economic impacts of animal diseases

“When we think about this center, it’s veterinary data, it’s the disease data, including disease prevalence and disease incidents, in addition to economic data, like prices and quantities,” says Pendell. “But it takes a whole team of people and including data from a whole bunch of different sources and different disciplines to come together to study these animal health economic issues.”

K-State was selected by the World Organisation for Animal Health , which represents countries within North and South America.

“There are 33 countries in the Americas region that are members of the World Organisation for Animal Health. You’ve got Canada, Mexico, the United States. You also have all of Central America, and then South America and the Caribbean Islands,” he explains.

Pendell says here at home, livestock producers across the country are on high alert about the potential threat of animal diseases.

“Upfront, some of the current diseases that are here are high-path avian influenza, which was introduced recently, and you have ASF (African Swine Fever) knocking at the door. That’s another one that’s important,” says Pendell. “We’re working on some other diseases, endemic diseases, like bovine respiratory disease, etc., with folks over in the College of Veterinary Medicine. So, there’s going to be more than one disease (studied), per se. It’s going to probably be more of a portfolio approach.”

Sorting Out Priorities By Country

But he points out every country is different, so the focus for the U.S. is not always the same as the concerns for a country like Brazil.

“I spent some time in Brazil last month where they’re talking about TB, they’re talking about brucellosis issues that are a little different than maybe here in the United States,” he says. “And so there’ll be a lot of different issues, a lot of different diseases that we will focus on.”

The team is currently carving out the answer to what the priority diseases are by country, to then uncover the potential impact of the animal diseases that pose the biggest threat.

“Right now, we’re trying to visit with the various governments, and the animal health officials in these countries, to figure out what are the issues that that are most relevant, timely for them,” says Pendell. “Eventually, as we get up and running, it’s going to be anywhere from the producer to the consumer, and everybody in between, including the governments.”

National Bio and Agro-Defense Facility Located Next to K-State

Conveniently located down the road from Pendell is the new NBAF facility, a joint effort between the U.S. Department of Agriculture (USDA), and the Department of Homeland Security (DHS), to protect agriculture against possible foreign animal diseases. While the research is not new, the location is.

“NBAF needed to replace Plum Island because Plum Island is more than 65 years old, and it doesn’t have the capability to meet growing research and diagnostic needs when it comes to emerging diseases, which are those that are new or not well known, as well as zoonotic diseases, which are those that transfer between animals and humans,” says Christian Young, biological scientist with the Foreign Animal Disease Diagnostic Laboratory. “So, NBAF will be able to continue as well as expand upon Plum Islands’ mission to protect U.S. agriculture and our food supply against terrorist attacks, major disasters and other emergencies.”

Pendell says having NBAF in Manhattan, Kan., was also a selling point to why the center he’s leading made sense, as he will explore the possible economic impacts of those potential diseases.

“The biggest opportunity being here in Manhattan, Kan., at Kansas State University, is I think the animal health industry here is only going to grow because of NBAF,” says Pendell. “I think there’s going to be so many opportunities in this space to add an economic component to the research that’s going on in this animal health space.”

An Important Tool for Livestock Producers, Livestock Industry

Pendell knows it’s a big undertaking, but it’s one that could change the game for livestock producers not just in Kansas, but around the globe.

“It’s important for livestock producers, because this is their livelihood. So our goal is to produce tools in which they can evaluate various biosecurity measures that can reduce the likelihood of a disease outbreak on their individual operation and protect their livelihood,” says Pendell.
