What Do Foot-and-Mouth Disease Outbreaks in Europe Mean for the U.S.?

Mon, 31 Mar 2025 13:19:03 GMT

Foot-and-mouth disease (FMD) is rearing its ugly head in Europe. After an outbreak in water buffalo in Germany in January, an outbreak in cattle in Hungary in early March and an outbreak in cattle in Slovakia last week, why now? What is the U.S. doing to keep this foreign animal disease out and protect the country’s livestock industry?

“FMD is caused by a virus that affects cloven-hoofed animals so that can include cattle, pigs, sheep and goats,” explains Megan Niederwerder, DVM, who serves as the executive director of the Swine Health Information Center (SHIC). “It does not affect humans and is not a threat to food safety, but it has significant trade implications once it is introduced into a country.”

FMD has been fairly quiet in these European countries – with no cases reported for decades. Other parts of Europe have seen outbreaks more recently like the 2001 outbreak in the United Kingdom that caused a crisis in British agriculture and tourism and resulted in the cancellation of the World Pork Expo held in Des Moines, Iowa.

“FMD really decimated the United Kingdom,” says Barb Determan who was serving as president of the National Pork Producers Council (NPPC) at the time. “It became very apparent that we couldn’t guarantee the safety for our U.S. pig herd because of the high numbers of international travelers that would be at the show. We had to cancel World Pork Expo out of an abundance of precaution.”

Although there is still a lot to be discovered about how FMD was introduced into these populations, it’s a significant warning to the U.S. to be on alert.

That was the first time, but not the only time World Pork Expo was canceled. The event was also canceled in 2019 because of the African swine fever outbreak in China and again in 2020 due to the COVID-19 pandemic.

“That was a hard financial decision,” Determan says. “We had just completed the separation agreement between NPPC and the National Pork Board. NPPC was very tightly budgeted at that time, so it was a huge hit.”

However, keeping the U.S. pig herd safe was the most important thing on everyone’s mind. She says they made their decision after hearing reports from veterinarians who had been to England to better understand the extensiveness as well as from the USDA that had sent veterinarians over to help.

“At that time, we didn’t have near the biosecurity practices and things that we do now with the disinfectant foot mats,” Determan says. “We also don’t have live pigs on the on the grounds now compared to how we did things many years ago. We used to have live pigs everywhere on the fairgrounds in the early 2000s from genetics companies with pigs in their displays to the pigs in the live shows.”

The Truth About FMD
The clinical signs of FMD are similar to what the name implies. It can cause vesicles or blisters on the feet, mouth and tongue of animals that are infected. The U.S. has not had a case of FMD since 1929.

“We certainly want to keep it that way, as the economic implications for producers are significant if the virus is introduced,” Niederwerder says.

Compared to many viruses, FMD is a highly stable, non-enveloped virus that allows it to be infectious for longer periods. It’s very contagious and highly transmissible. Not only are there risks with transmission of the virus through infected meat products that may come in through illegal trade, but it can also be carried on contaminated clothes or equipment or supplies of humans.

“The human would not be infected, but certainly people can carry the virus on contaminated clothing,” Niederwerder says. “That’s why it’s really important as we think about prevention of entry into the U.S.”

FMD causes fever and pain. It results in excessive salivation and causes reduced milk production in dairy cattle.

“When you think about the impact, certainly there’s an impact on animal health with regards to the clinical signs, but even further is this impact on trade restrictions and the economic losses for producers,” Niederwerder says. “When you try and contain the virus, that oftentimes results in those infected animals being culled or euthanized so the disease no longer has the chance to spread.”

Why Should the U.S. Pay Attention?
When a virus moves into a new geographical range or is reintroduced into a country that has maintained a negative status for a long period, Niederwerder says it’s critical to reassess the risk to the U.S.

“In January, Germany reported their first case in over 30 years in water buffalo near Berlin,” she explains. “It was 14 animals, and those animals were all culled after the infection was confirmed but certainly trade restrictions and implications on surrounding areas of that Berlin farm were significant.”

Fast forward to March when two additional countries have reported cases. Hungary reported FMD in a single farm of cattle in the north part of the country for the first time in over 50 years. Shortly thereafter, the virus appeared in Slovakia (who also hadn’t seen a case in over 50 years) in multiple herds of cattle.

“Just recently, another herd was a suspect herd in Slovakia, near the southern border near Hungary,” Niederwerder says. “This is certainly concerning about how this virus is being reintroduced. Is it associated with contaminated fomites that may be in the country or traveling to new locations? Is it associated with wild boar? Could it be associated with infected hay?”

Although there is still a lot to be discovered about how FMD was introduced into these populations, it’s a significant warning to the U.S. to be on alert .

“We need to do everything we can to make sure it doesn’t get reintroduced into the U.S.,” Niederwerder says. “How can we amp up any biosecurity measures that are necessary to reduce our risk? We also need to think about reducing the risk of introduction into our country through travel and illegal trade.”

Be on Alert
Livestock operations should reevaluate biosecurity protocols. If any of your farm’s employees travel to areas where there are infected animals, implement a quarantine period for entry back into your U.S. farm, she advises.

“Be vigilant,” Niederwerder urges. “One of the challenges of FMD is that it does cause these characteristic lesions of vesicles or blisters on the mouth, nose or the hoof. What becomes very tricky is that those clinical signs are indistinguishable from other vesicular diseases such as Senecavirus A. If producers and veterinarians see these lesions, they must report it immediately so it can be investigated and confirmed that it is not FMD virus.”

FMD is not just a disease of pigs and cattle, she points out. Sheep, goats and cloven-hoofed zoo animals may also be impacted by FMD. This increases the breadth of what the industry needs to monitor.

“The world is very small now,” Niederwerder says. “Not only do people travel more internationally, but animals move around more than ever, too. It’s extremely important for those of us that are producers to keep our eyes open and pay attention to what’s going on worldwide so we can be as prepared as possible for any change in disease risk.”

That’s one of the ways that SHIC is trying to help producers. SHIC provides timely domestic and global disease updates to producers.

“Watching the SHIC global disease report is really important for producers,” Determan says. “It comes out every month and really gives you a feel for what’s happening in the entire world from a swine health standpoint. The biggest lesson we learned from the 2001 FMD outbreak is that looking farther out than just our own farm gate is so important.”

5 Reasons Consumer Distrust In Our Food Supply Is Rising

Tue, 28 Jan 2025 20:38:14 GMT

Bread, check. Blueberries, check. As I wheel my grocery cart alongside the deli case, I’m taken aback at what I see. Rather, it is what I don’t see that has me wondering, “What in the world?” This section of my favorite grocery store is now almost completely empty, except for a couple of ham loaves and a renegade block of cheese.

In a slightly distraught tone I ask the worker behind the counter, “What’s going on?” He hesitates for a moment, then replies, “The store is in the process of changing suppliers for our deli products. We should have more of a selection next week.” Then it dawns on me: my favorite brand of deli meat and cheese, Boar’s Head, has officially been blacklisted by my go-to grocery store.

I should not have been surprised. Boar’s Head began its fall from public grace on July 26, 2024, when the company issued a recall for more than 207,528 lb. of product due to potential listeria contamination. The CDC linked the contamination to 61 illnesses and, tragically, 10 deaths. It was the worst listeria outbreak in the U.S. in over a decade.

The outbreak was ultimately traced to a production line at the company’s Jarratt, Va., plant. According to USDA inspection reports, which USA Today had to obtain through a Freedom of Information Act request, 69 reports of non-compliance were recorded at the Jarratt plant between 2023 and 2024. What was in those reports was unsettling. Documentation of insects live and dead, black and green mold, mildew, dripping and standing water, as well as other unsanitary conditions within the plant in the weeks leading up to the July recall. In a move that was too little too late, Boar’s Head announced on Sept. 13, 2024 that the Jarratt plant would be closed permanently.

In 1906, Upton Sinclair published his famous novel “The Jungle,” which exposed the horrific conditions in the meatpacking industry at the time. The writer’s work proved to be an instant bestseller to the masses. The irony is that nearly 120 years later, one might find it hard to discern whether they’re reading a current USDA Food Safety and Inspection Service (FSIS) report or a chapter straight out of “The Jungle.”

Just One Of Many
The Boar’s Head case was only one the high profile food recalls last year. Remember the E. coli contaminated onions on McDonald’s quarter pounders? Then, Costco issued a massive recall on their Kirkland Signature brand of organic eggs because of a threat of Salmonella. And to cap off the year with the scariest illness yet, on Dec. 18, 2024, the CDC confirmed a patient in Louisiana had been hospitalized with the nation’s first severe case of avian influenza A (H5N1) virus, aka the “bird flu.”

If it seems that the number of food recalls are coming at us at a more fast and furious pace than ever, then your gut instinct is spot on. The Food and Drug Administration, which reports food and cosmetics together, says 1,908 such products were recalled in the fiscal year that ended in September. That’s the highest number since 2019. Such a constant barrage of warnings is having a serious affect on consumers’ overall psyche — and not in a positive way. According to a September 2024 Gallup report, only 57% of Americans say they have a “great deal” or “fair amount” of confidence in the government to keep food safe. This number is a 27 point decrease since 2019, and is a record low for the Gallup Consumption Habits Poll since its inception in 1999.

This explosion of 20th century foodborne illnesses has me asking the same question I asked the worker behind the deli counter: “What’s going on?”

5 Reasons To Be Skeptical
There are multiple reasons consumers have good reason to be less confident in the safety of their food.

First, there’s the government. Second, more and more of our food is imported, which makes it harder to inspect. Third, you have a growing quest for more natural food, which sometimes circumvents traditional inspection channels. Fourth, industry consolidation means only a handful of players control both the production and processing. That’s not inherently a bad thing, but if something goes wrong, it’s probably going to be big. Finally, we now have the ability, through more technology and data, to find, detect and isolate the specific source of contamination and document it.

Time For An Overhaul
Food safety policy and implementation at the government level is in need of a serious overhaul. There is a chance it could actually happen. In 2018, the previous Trump administration proposed consolidating federal food oversight into a single agency with USDA.

There are so many common sense things that a fully functioning food agency could do. For one, start with better and more noticeable country of origin labeling (COOL) on imported foods. It should be prominent, displaying the country’s flag as the primary indicator of origin. If nothing else, we’ll all get better at geography. Next, companies that embrace new technologies that prevent contamination should be rewarded with tax credits. We do it for electric cars. Why not for safer food?

Finally, the most important change needs to come in the form of accountability and transparency both from the food industry itself and the government that regulates it. That didn’t happen in the case of Boar’s Head, and 10 people lost their lives because of it. In the age of AI and social media, those FSIS plant inspection reports should be posted on platforms such as X and Facebook for the public to see in real time. Without such transparency, we’re no better off than we were back in 1906.

USDA Reports First H5N1 Detection in Swine

Wed, 30 Oct 2024 20:36:09 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.
