Take the Climate Resilience Producer Survey

Kim Vaughn
Communications

Navigating climate challenges in Washington's agricultural landscape

Rich soils, diverse climates, and large-scale irrigation infrastructure make Washington one of the most productive agricultural regions in the world. Washington farmlands and farmers are of global importance, moving more than $17 billion per year in food and agricultural products through Washington's ports, producing over 300 different crops, and generating $12.8 billion per year in agricultural production value for the state economy.

These activities are critical to urban and rural communities alike, providing food security, nutrition, and thriving livelihoods in Washington and beyond.

Extreme weather, invasive pests and disease, and declining water availability are daily impacting agricultural production in Washington. Managing the wide range of potential climate risks and costs moving forward has made livestock and crop production—already challenging and volatile industries—even more challenging. However, with the right support and innovation, Washington farmers are poised to lead the way in building a more economically viable and climate-resilient future. 

The Washington State Department of Agriculture, Climate Resilience Plan, is one important step towards that goal. 

Climate Resilience Plan

To support the continued viability and vitality of Washington agriculture, WSDA has launched an 18-month climate resilience planning process, in partnership with Washington State University. The Climate Resilience Plan will summarize recent climate science, identify vulnerabilities, highlight opportunities, and include newly developed resources. We intend for this work to be informed by the needs and experiences of Washington producers. It is essential that your voice is heard.

Take the survey

Your responses will help us understand the on-farm impacts of climate change, resources in use, and current agricultural needs.

We want to hear from small and large producers from every crop and animal operation in every part of the state.

This information will help us communicate the nuances of climate change in agriculture to industry stakeholders and policymakers, and to build programs that are in direct response to your feedback. Your input is valued and appreciated.

Survey participants will be entered into a drawing to win a $100 VISA gift card.

The survey is available in English and Spanish. 

Please take a few minutes to fill out this short, anonymous survey by February 23, 2024.

We thank you for your participation in this effort.

CSI meets agriculture: WSDA's pathology lab leads next-gen pest detection

Telissa Wilson
WSDA Plant Pathology and Molecular Diagnostics Lab

Did you know WSDA’s Plant Pathology & Molecular Diagnostics Lab (PPMDL) uses cutting-edge molecular tools to detect unwanted pests and pathogens? Our PPMDL lab runs tests and uses equipment that many of you have probably seen on CSI or heard about in recent years due to COVID-19. PPMDL tests a wide variety of materials and runs an even wider array of tests, all with the shared goal of finding pests early and preventing them from being established. 

Like a forensic lab, PPMDL maintains highly trained staff, follows strict quality control measures, contributes to research and development of detection tools, and often collaborates with a wide array of organizations. Below is a snapshot of some recent work that showcases PPMDL projects straight out of a CSI episode.

Haplotyping invasive weeds

Sometimes it can be difficult to differentiate between species - whether it is a weedy plant or an invasive insect. Is this species a crime suspect or victim? Haplotyping compares genetic information among different samples to better understand how closely the samples are related - whether it is a native species or a wolf in sheep's clothing. 

Enter suspect number 1:  the highly invasive, aquatic grass Phragmites australis. Because the different subspecies of Phragmites grass are so difficult to tell apart visually, their haplotypes are used to assign them a native or non-native status, which is needed to guide treatment plans. 

For this work, PPMDL staff first extract DNA from submitted leaf samples. Then staff use a process called Polymerase Chain Reaction (PCR) to copy the DNA of very specific regions- regions that have been empirically determined to be good markers for haplotyping in a given species. The last step requires sequencing of the resulting PCR product so the sample haplotypes can be compared against a database of known haplotypes. In the case of Phragmites australis, haplotyping has allowed wetland managers across multiple agencies to preserve their native grass stands and only destroy the invaders. In our CSI analogy, you could say that haplotyping ensures that only the true perpetrator - Phragmites australis – does time for the crime. 

Forensic swabbing for trace DNA

Forensic swabbing can detect
where a pest has been. 
One of the biggest challenges in preventing the establishment of an invasive species is detecting the pest very soon after it is introduced. Sometimes WSDA receives reports of suspected invasive species, but the specimen was not collected and a determination cannot be made if a photo was provided. But what if you didn’t need a specimen – or even a photo – to confirm that a pest had been at a particular location?

You have probably seen shows where crime scenes are swabbed for the presence of DNA left behind on surfaces. These swabs are then shipped to a forensic lab, where scientists extract DNA and perform various molecular tests to analyze the sample. Even though forensic scientists have been utilizing trace DNA for decades to confirm presence at a crime scene, using trace DNA to detect agricultural pests is in its infancy. 

eDNA

Our pathology lab is changing that. PPMDL has been using swabs to collect environmental DNA (eDNA) left behind by two invasive insects – the spotted lantern fly (SLF) and the northern giant hornet (NGH). Once validated, these assays can confirm the presence of SLF and NGH at sites where a physical sample cannot be collected and early on before pest density is high enough to use alternative survey methods.

Pathogen detection

An exponential curve corresponds
to positive detection in a qPCR test
When someone passes away and the cause of death is unknown, forensic scientists may test for the presence of certain pathogens. PPMDL uses these same molecular methods to test for plant pathogens that threaten our state’s numerous agricultural resources. Quantitative Polymerase Chain Reaction (qPCR) is a highly specific and sensitive method that PPMDL routinely uses. In fact, PPMDL ran over 2,500 qPCR tests for plant pathogens alone in 2022! These test results help clear exports for trade, certify growing areas free of pests, and help prevent the establishment of high-risk pests through early detection surveys. 

DNA analysis of fecal samples

PPMDL conducts fecal analysis
to determine hornets' diet
One of the strangest-sounding projects that PPMDL has taken on recently involved extracting DNA from giant hornet fecal pellets to discover what the larvae were being fed here in Washington. To do this, PPMDL scraped fecal pellets from inside combs of the four nests that the WSDA Pest Program eradicated. They then extracted the total DNA, which theoretically contains traces of DNA from each organism that was fed to the larval hornet. Next, PPMDL used PCR to amplify a universal genetic segment (called the COI barcoding region) found in all insects and animals. Using advanced molecular magic (aka indexed metabarcoding) PPMDL was able to obtain thousands of genetic sequences that could be correlated to specific prey species. This work allowed researchers to see what NGH has been eating in Whatcom County and how that contrasts with diets in its native habitats. 

What did we find? Well, many folks have heard that northern giant hornets are a major threat to honey bees, but many other pollinators were also on their menu. PPMDL also found that bald-faced hornets made up a majority of the sequences obtained across all nests. Check out this "Wings menu" our Communications folks put together showing some of what they were eating.

Natural Resources Assessment Section gets a new identity: Welcome to "Natural Resources and Agricultural Sciences"

Kim Vaughn
Communications

We have some exciting news to share! The Washington State Department of Agriculture (WSDA) is undergoing a transformation that reflects our commitment to innovation, expansion, and adapting to the changing landscape of natural resource management. Our esteemed Natural Resources Assessment Section (NRAS) is now evolving into the more encompassing "Natural Resources and Agricultural Sciences." This rebranding marks a significant step forward in our mission and objectives.

Embracing a new identity

The decision to rebrand our Natural Resources Assessment Section to "Natural Resources and Agricultural Sciences" comes after careful consideration. We believe this updated name better represents the diverse spectrum of activities, research, and initiatives we engage in. Our work extends beyond traditional assessment, encompassing cutting-edge agricultural sciences. This shift mirrors our dedication to excellence, sustainability, and a holistic approach to resource management

What is NRAS?

The NRAS has been diligently working at the interface between agricultural production and environmental quality. Our research spans various critical areas, including:

    1. Agricultural land use practices:   NRAS specialists map and inventory crop acreage through visual surveys, aerial/satellite surveys, and federal data. This data helps us review current crop production and evaluate changes in land use through the years, including land removed from production.
    2. Pesticide usage: We meet with grower groups, consultants, and industry representatives to compile anonymized information about pesticides used, application rates and dates, and modes of application on different crops. This helps us understand changes in pesticide usage and pest pressure.
    3. Water quality: NRAS works to understand how pesticides and fertilizers might affect Washinton State’s water resources. We monitor water for pesticides and work with other programs at WSDA, the agricultural community, and regulators on education and outreach about our findings and good management practices for pesticide use.
    4. Water quantity: A reliable water supply is essential for Washington’s agricultural production. We study water supply issues throughout the state to see how things like increased drought frequency may affect agriculture. We also work to make sure needs and challenges specific to agricultural producers are addressed in water supply projects throughout the state. .
    5. Soil health: Soil serves as the fundamental basis for agriculture, and it is of utmost importance to ensure its well-being. We work with partners at the Washington State Conservation Commission and Washington State University in the Washington Soil Health Initiative (WaSHI). Through research, outreach and education, funding, and policy support, WaSHI improves soil health in Washington for increased agricultural resilience and economic viability.  

Our ongoing commitment

The programs under the NRAS umbrella have a shared goal: to protect public health, preserve the environment, and support the viability of agriculture in Washington. Our dedication to excellence remains steadfast as we continue to work tirelessly to achieve these objectives.

For more information about our programs and the important work we do, we invite you to visit the main NRAS webpage. There, you can delve deeper into our research, initiatives, and the ways in which we are contributing to the sustainable future of agriculture and the environment in Washington state. We are excited about the possibilities that lie ahead and are grateful for your continued support as we embrace this new identity and all the opportunities it brings. Together, we will make a positive impact on the future of agriculture and natural resource management.

Fun with a purpose - the Washington Bee Atlas trains volunteers to map native bees

Karla Salp
Communications

Dr. Karen Wright demonstrates how to net bees. 
The air was chilly last Saturday as over a dozen people of various ages and backgrounds gave up a weekend to trudge out in hiking boots to a remote meadow near Sequim. The early morning, the fact that it was a weekend, and the distance from home for many of them proved that the group was truly passionate about the day’s work: learning to document the state’s native pollinators.

Oh, did I mention they are also all volunteers?

These dedicated few are some of the first to join and volunteer for a new project at the Washington State Department of Agriculture: the Washington Bee Atlas. The goal of the project is to document the state's native bees under the guidance of the WSDA’s first melittologist, Dr. Karen Wright.

Fun and fascinating – collecting native bees

Volunteers scout for bumblebees to catch and 
release with their insect nets.
Half of the volunteers were new to the project, but everyone was in high spirits, chatting about how they came to be involved. The day started by teaching new volunteers how to take and upload pictures of flowers to iNaturalist to record what the bees were pollinating and where.

Next was learning to net specimens. As the morning was cool, only bumble bees were out, which gave the participants an opportunity to practice “catch and release” with the fuzzy fliers, learning the “figure eight swoop” to ensure the specimens stayed in the net.

Now swinging the pros, volunteers next learned how to safely “charge” the collection vials, net a bee, and put it in the vial for euthanization* and preservation. Luckily, as the day warmed, the native bees became more active and the group had luck finding and netting over 20 species from that single location!

Last on the list was learning how to pin specimens so they could be preserved and later identified to species. The group found this is none too easy as some bees are extremely small. Once the specimens are identified, all of the data will be available on an online public dashboard.

Everyone was quick to pick up the basics needed to collect bees. It was a fun and funky group to be around. Everyone was fascinated by the bees they were finding, sometimes surprised when it came to pinning the bees that bees they thought were the same while collecting proved to be different when they took the time to pin and preserve them. Many stuck around to collect at another location in the area on Sunday.

“Anyone can learn to collect native bees in less than a day. Field work is a fun way to learn about the pollinators around us while improving our collective knowledge about our bees and how they interact with our environment,” Dr. Wright said.

Why native bees?

Very little is known about Washington’s native bees. We aren’t sure how many species are in the state and we can’t say whether they are doing well or declining. It is impossible to say how various changes — from agriculture to changes in climate to urban sprawl — are affecting them.

The map below shows known sightings of what is believed to be about 600 species of native bees in Washington. It amounts to about one dot per species believed to be in the state. In other words, we know almost nothing about native bees as a whole and there are many large areas in the state with no records at all.

The Washington Bee Atlas aims to change all that. Dr. Wright is responsible not only for training the volunteers and running the program, but for identifying all the bees that the volunteers collect as well.

The project does not collect bumble bees (which are already tracked in the Pacific Northwest Bumble Bee Atlas) or honey bees, which are not native.

A successful model

While the program is new to Washington, the Washington Bee Atlas is not reinventing the wheel. The program is modeled on the Oregon Bee Atlas, which has been in place for several years. In fact, the two programs are collaborating. The Oregon Bee Atlas has developed such a thorough virtual training that Washington’s Bee Atlas volunteers will be taking it as well.

Once fully trained and certified, the volunteers will be able to collect under WSDA’s bee collection permits for the research project. (Did you know you have to have permits to collect wildlife in Washington?)

Volunteering with the bee atlas

To participate in the Washington Bee Atlas, volunteers must complete training to ensure they can properly identify and collect only native bees.

Applications are accepted on an ongoing basis, although training opportunities and field days may be limited to certain times of the year. If you are interested in learning more about the Washington Bee Atlas or would like to volunteer, visit WSDA’s Washington Bee Atlas webpage. Registration for the next virtual training session closes Aug. 2. The next field day is Aug. 11 at Snoqualmie Pass. For more information, visit our website or contact Dr. Karen Wright at karen.wright@agr.wa.gov.

*Euthanization is a necessary part of this research project as many species cannot be identified without examining the specimen itself.

Six ways you can help #BeatTheBeetles

Karla Salp
Communications

First WSDA-trapped Japanese beetle of 2023
The first Japanese beetle of 2023 has been detected! Our Japanese beetle trappers were out checking traps this morning and they discovered the first beetles in a trap near the high school in Grandview. So the adults are here and it is time to take action!

We conducted our second beetle treatment this spring and WSDA trappers have placed hundreds of traps in and near previous beetle detection sites that we’ll be checking regularly until the fall.

We’re doing everything we can to protect schools, parks, gardens, and farms from this invasive pest, but there are many ways that you can help.

  1. Report Japanese beetle sightings. If you spot a Japanese beetle (or several,) snap a photo and report them online or by emailing pestprogram@agr.wa.gov.

  2. Place your own traps. You can join the trapping effort by placing your own traps. Traps can be obtained at local farm and garden centers as well as online. If you do trap, please either count and report your trap catches online (with a photo of your catch!) or drop off traps with beetles in them at the following locations:

         - Valley Wide Cooperative (Grandview)
         - Riders True Value (Grandview)
         - Wapato City Hall (Wapato)

  3. Treat your property. If you notice beetles on your property, you may want to apply an effective treatment for adults (WSDA’s treatment earlier in the year was for grubs.) Washington State University has provided guidance to homeowners in English and Spanish on the best products for Japanese beetles (not all products listed for Japanese beetles have been proven effective.) If you choose to treat your property, follow the label instructions on using the product exactly.

  4. Graphic asking people not to spread Japanese beetle through yard waste, potted plants, or soil.
    Don’t move plants.
    If you live in or near an area where Japanese beetle has been found, do not move plants. Sharing plants from your yard with a friend or neighbor could spread the beetle from your yard to theirs. Don’t purchase plants from inside the quarantine area and take them home if you are outside the quarantine area. You could bring Japanese beetle into your yard.

  5. Keep yard waste and soil in the quarantine area. Yard waste and soil could also transport beetles. Moving plants, yard waste, or soil out of the quarantine area is prohibited if you live in the quarantine area. Instead, WSDA has established a yard waste drop-off site at 875 Bridgeview Rd. Grandview, WA.

  6. Spread the word, not the beetles. Learn more about Japanese beetles and encourage your friends and neighbors to help detect and eradicate this pest. On our Japanese beetle webpage, you can learn more about the beetle, how you can help, join our Washington Japanese Beetle Watch Facebook group, and sign up for email alerts to stay informed about the project.
Successfully eradicating the Japanese beetle from Washington is going to take several years. By working together, we can protect Washington from this invasive pest and #BeatTheBeetle.

Seis maneras en las que puede ayudar a #CombatirLosEscarabajos
 
Se detectó el primer escarabajo japonés de 2023. Esta mañana, nuestros tramperos de escarabajos japoneses revisaron las trampas y descubrieron los primeros escarabajos en una trampa cerca de la escuela secundaria en Grandview. Los adultos ya están aquí; por lo tanto, es momento de poner manos a la obra. 

Durante esta primavera, hemos realizado nuestro segundo tratamiento contra los escarabajos y los tramperos del Washington State Department of Agriculture (WSDA) han colocado cientos de trampas en los lugares anteriores donde se detectaron escarabajos y cerca de ellos, los cuales revisaremos con regularidad hasta el otoño. 

Estamos haciendo todo lo posible por proteger escuelas, parques, jardines y granjas de esta plaga invasora, pero usted también puede ayudar de numerosas maneras. 
  1. Notifique avistamientos de escarabajos japoneses. Si ve un escarabajo japonés (o varios), tome una fotografía y notifique en línea o por correo electrónico a través de pestprogram@agr.wa.gov. 

  2. Coloque sus propias trampas. Puede colaborar con los esfuerzos de colocación de trampas al colocar las suyas. Puede obtener las trampas en centros agrícolas y de jardinería locales, así como por internet. Si atrapa escarabajos, cuéntelos y notifique en línea (adjunte una fotografía de los escarabajos capturados) o entregue las trampas con los escarabajos en los siguientes lugares:

         - Valley Wide Cooperative (Grandview)
         - Riders True Value (Grandview)
         - Wapato City Hall (Wapato)

  3. Realice un tratamiento en su propiedad. Si detecta escarabajos en su propiedad, puede aplicar un tratamiento eficaz contra los adultos (a principios de año, el tratamiento del WSDA era contra los gusanos). Washington State University ha elaborado pautas para los propietarios en inglés y español sobre los mejores productos contra los escarabajos japoneses (no todos los productos que se enumeran para combatir el escarabajo japonés han demostrado ser eficaces). Si decide realizar un tratamiento en su propiedad, siga con exactitud las instrucciones que figuran en la etiqueta sobre cómo usar el producto. 

  4. No traslade plantas de un lugar a otro. Si vive en una zona donde se detectaron escarabajos japoneses o cerca de ella, no traslade plantas. Compartir plantas de su jardín con amigos o vecinos podría propagar los escarabajos de su jardín al de ellos. No compre ni lleve a su casa plantas que pertenecen a la zona de cuarentena si usted vive fuera de dicha zona. De esta forma, podría traer al escarabajo japonés a su jardín. 

  5. Mantenga los desechos de jardín y la tierra en la zona de cuarentena. Los desechos de jardín y la tierra también podrían transportar escarabajos. Está prohibido trasladar plantas, desechos de jardín o tierra fuera de la zona de cuarentena si vive en dicha zona. En cambio, el WSDA estableció un sitio de depósito de desechos de jardín en 875 Bridgeview Rd. Grandview, WA.

  6. Difunda el mensaje para que los escarabajos no se propaguen. Obtenga más información sobre los escarabajos japoneses y aliente a sus amigos y vecinos a colaborar con la detección y erradicación de esta plaga. En nuestra página web del escarabajo japonés, puede leer más sobre el escarabajo y cómo puede ayudar, puede unirse al grupo de Facebook “Washington Japanese Beetle Watch” (Detección del escarabajo japonés en Washington) y puede registrarse para recibir alertas por correo electrónico para mantenerse al tanto sobre el proyecto. 
Erradicar definitivamente el escarabajo japonés de Washington va a demorar varios años. Si trabajamos juntos, lograremos proteger a Washington de esta plaga invasora y #CombatirLosEscarabajos.

Watch a wasp nest to help detect northern giant hornets

Cassie Cichorz
Pest Program

Paper wasp on a nest in Washington State

Did you know you can help protect Washington from invasive species just by taking a walk around your house or barn once a week? 

Over the last few years, residents of Whatcom County and WSDA staff have noticed hornets attacking paper wasp nests. In 2021, WSDA tracked a hornet and observed it repeatedly visiting the same paper wasp nest. Each visit lasted five to ten minutes and the hornet removed paper wasp larvae.  

WSDA invites you to help watch for northern giant hornets (Vespa mandarinia). Join our community science project to locate active paper wasp nests, watch the nests weekly, and record your observations from June through October. WSDA will continue to invite residents to participate in public scientist trapping too.

paper wasp nest on a house in Whatcom County

Paper wasps (Polistes dominula) can grow to about three-quarters of an inch long and have a well-defined “wasp waist” that makes them easy to identify. Paper wasps are typically not aggressive and do not readily attack people, but they can sting if threatened. They form small colonies and build hanging, open-comb nests on building eaves, frames, abandoned cars, or branches of trees and shrubs. Paper wasp nests vary in size and are usually gray to brown in color. They are made up of many exposed cells that are less than an inch deep. Nests typically range from the size of a quarter to a coffee can lid, but can be larger.

Although we invite anyone in Washington to participate in adopting a paper wasp nest, we are particularly interested in observations from Whatcom, Skagit, Island, San Juan, Snohomish, King, Jefferson, and Clallam counties.

Paper wasps tending their nest
LOCATE

Starting in June, locate active paper wasp nests that you have access to and can monitor through October. Log the nest locations using the Watch a Wasp Nest Registration Form. After submission, you’ll receive an email confirmation which will include a unique Nest ID assigned to your nest location. You will need to save this Nest ID to use during weekly check-ins. Access the registration form.

MONITOR

Each week visit the nests. Watch for any hornet or wasp activity happening at the nest. WSDA asks you to monitor the nests for at least five minutes during the day once per week, but you can check the nests as long and often as you would like.

REPORT

After monitoring you will need to report each of your observations on the Watch a Wasp Check-in form. You will also need your Nest ID which was received in a confirmation email. Click here to access the check-in form.

However, if you think you spot a northern giant hornet (it will be significantly larger than the paper wasps), safely take a photo and report it at agr.wa.gov/hornets or by emailing hornets@agr.wa.gov.

Stay Connected

WSDA is dedicated to working with the public and to providing information on northern giant hornets.

Sign up to help WSDA watch for high-priority invasive pests

Karla Salp
Communications

Is tomato fruit borer lurking in your garden? Or is Scots pine blister rust on your tree? Early detection is critical for protecting the state’s forests, parks, farms, and gardens from invasive pests and diseases.

That’s why WSDA’s Pest Program has a new project to be on the lookout for some of the nation’s highest-priority pests and plant diseases that are not yet known to be in the state.

The program will look for national high-priority pests including pests like spotted lanternfly, which has rapidly spread and decimated vineyards in the Eastern U.S.; apple proliferation phytoplasma, a type of bacteria that inhabits, impedes, and kills orchards; and the tomato brown rugose virus, which stunts tomatoes making their fruits unpalatable.

To look for these and other* pests, the WSDA Pest Program needs your help. They are asking farms, community gardens, parks, and even private property owners to sign up to participate in the project this summer. There are two ways to participate:

  • Summer trapping – WSDA trappers will place traps early in the summer and check them several times throughout the season. The traps will be removed in the fall.
  • Single site visit – WSDA staff will visit the site once to perform a visual inspection for pests. 

Specifically, the team is looking for properties that will have one or more of the following on-site this summer: 

  • Fruit or nut trees
  • Vegetables
  • Fruiting shrubs/vines
  • Ornamental trees/shrubs

While anyone in Washington is welcome to sign up, the program is especially interested in sites near highways or ports.

If you are willing to participate by offering your property for trapping or a site visit, please sign up to have your location considered. The Pest Program will review your information and contact you by May 15, 2023, to let you know if your property has been selected as a pest survey site for the upcoming season.

WSDA has a long history of looking for invasive pests to prevent them from establishing in the state. For example, the longest-running program is the invasive moth program, which has kept spongy moth (formerly known as gypsy moth) from establishing in Washington (despite numerous introductions) for almost 50 years. Public support and participation have always played a key role in protecting our state from invasive pests and diseases.

With your support and early detection, there is a much higher chance of eradicating or significantly slowing the spread of any new pest.

It is grasshopper season and, if you live near Everett, it is a good time to keep your eyes peeled for an unusually large grasshopper with unusual eyes.

An Everett resident reported one Egyptian grasshopper (Anacridium aegyptium) to Washington State entomologists earlier this year and USDA entomologists recently confirmed it as the first detection of the insect in Washington State. The Washington State Department of Agriculture will conduct visual surveys in the area but is asking the public to also be on the lookout for this large grasshopper with striped eyes.

The grasshoppers typically feed on plant leaves. Adults are usually olive, gray, or brown in color and are most likely to be seen toward the end of summer. Young grasshoppers can be green and may blend in with vegetation. Males can grow to over two inches

long and females can be almost three inches long. The key to identifying these insects is their eyes - they have distinct black striping on their eyes that sets them apart from other grasshoppers.

“An overwintering grasshopper could easily hitchhike, so this is another case where we are asking the public to help us figure out if this is just a single specimen,” Sven Spichiger, WSDA managing entomologist, said. Only one living, but sluggish, grasshopper has been confirmed. There is currently no evidence of an established population.

Residents near Everett who believe they have seen this insect should send a photo to pestprogram@agr.wa.gov for identification and include the location where it was spotted. If you believe you have seen one outside of Washington State, please take a picture of it, note the location, and report it to your State Plant Regulatory Official or State Plant Health Director.

Egyptian grasshoppers are generally regarded as a minor pest of concern in their native habitat but could be an occasional pest to crops, orchards, and vineyards. USDA is gathering available scientific information to help determine the potential risk of this insect.

At the fair, make sure show animals get “the blue, not the flu”

Karla Salp
Communications

As wild and domestic bird flu cases continue to expand to additional counties across Washington, another influenza (flu) strain is also picking up in the U.S. Last week, the Centers for Disease Control and Prevention (CDC) confirmed the fourth case of swine flu in a human – this time in Oregon.

Influenza viruses can be passed between humans, birds, and pigs. Because of this, it is important to practice good biosecurity whenever interacting with either birds or pigs on your farm and when attending fairs and livestock shows.

Swine flu viruses are different from seasonal flu viruses that infect people. Flu vaccines don’t generally protect against swine flu; they protect people against seasonal flu, which can also spread to pigs.

No swine flu vaccine is available for animals yet in the United States, but work is being done to get an approved vaccine to use for control in the face of an outbreak, with promising vaccines demonstrating 100% efficacy in swine.

Swine flu can spread among pigs throughout the year, though rates increase significantly when infected pigs spend more than three days at a fair or livestock show. Reducing the time pigs spend at fairs to three days or less is one way to reduce the risk of spreading swine flu. The Swine Exhibitions Zoonotic Working Group has also produced a checklist for exhibition organizers and youth organization leaders to minimize the spread of influenza, which includes recommended actions to take before, during, and after exhibitions.

For exhibitors as well as visitors to pig exhibits, these recommendations help prevent the spread of flu between pigs and humans:

  • Avoid close contact with pigs that look or act ill. For exhibition organizers, pigs should be observed daily for flu-like symptoms. 
  • Wash your hands with soap and running water before and after contact with pigs or visiting a swine barn or exhibit. Use an alcohol-based hand rub if soap and water are not available.
  • People that are 65 or older, children under the age of 5, people who are pregnant, and people with certain long-term health conditions have higher risk of serious flu complications and should consider avoiding pigs and swine barns.
  • Keep food, drinks, and baby items, such as toys, pacifiers, bottles, and strollers, out of areas where there are pigs.

“After the fair, don’t bring home more than that blue ribbon,” Dr. Amber Itle, Washington State Veterinarian, said. “When showing animals – especially pigs and birds – take extra precautions to prevent the spread of swine flu and other diseases.”

But don’t think it is just the pigs that can infect humans. Humans can also infect pigs, so if you are not feeling well, take precautions to prevent spreading disease to your animals or have someone else care for your animals until you feel better.

If you own both birds and pigs, they should always be kept separate to reduce the risk of infection and mutating viruses. Prior to COVID-19, the last global pandemic was swine flu in 2009 – infecting an estimated 60 million people and resulting in over 12,000 deaths in the United States alone. That strain had signs of combined human, bird, and swine origins.

Given the high numbers of detection of bird flu throughout the country this year, adding swine flu to the mix is an unwelcome prospect – increasing the risk of another infectious and potentially deadly influenza strain. Keeping pigs and birds separated and practicing good biosecurity could prevent the next pandemic.
