Something to Chew On

Milling of wheat into flour seems like it would be pretty straight forward. An application that simply requires running seed though a crushing process and sifting out the flour as the appropriate particle size is reached. The reality is milling is very complex, technically challenging and requires fully interdisciplinary participation. Variations in the quality of the flour from the perspective of baking performance in large scale production has always been challenging. This is particularly true when growing seasons change the seed mix and the impact of temperature, moisture, fertilizer use, pest pressure and more changes the quality characteristics of the flour. The need for highly educated professionals in this area has never been greater and with the expertise of the likes of Dr. Kali Siliveru, K-State is laying the groundwork for preparing the next generation of professionals to better understand the impact of the milling process on the quality and safety of foods we eat every day.

Is our current food system sustainable? The consumption of seasonal, locally produced food sustains nutritional value, reduces the carbon footprint, and supports the growth of local economies. In many ways we have lost our connection to food — including understanding where our food comes from, how it is produced, the comradery developed in sharing food, and why it is important to eat seasonally and with intention. In this episode, we talk with Nat and Alison Bjerke-Harvey, co-owners of Piccalilli Farm in Geary County outside of Manhattan, KS. With formal training in history and environmental biology, Nat and Alison’s interest and passion for food has taken them beyond those areas of study headlong into the food system. From baking to cheese making, they have now landed squarely in the arena of sustainable farming and community building. Is it time to rethink what a sustainable food system is?

There are so many needs when it comes to food, including the availability of food and its impact on health. How does one make a difference to meet these needs? The ability to identify needs and a passion for making a difference is what drives today’s guest, Vickie James, Coordinator of the Manhattan/Riley County Food and Farm Council. In this discussion, Vickie details the Food and Farm Council’s work to increase knowledge, build partnerships and provide solutions to the complex food system challenges in our local community.

Food availability and food security are not always guaranteed on college campuses. Issues of food insecurity and a lack of food certainly do not end at the campus borders, but rather extend out into the city, the region and the world. If we treat these problems individually, we will fail collectively. Where does student health fit into the global food system? How does nutrition connect to a college student’s overall quality of life? Kathleen Hatch, Morrison Family associate vice president for student well-being, joins the podcast for a conversation about K-State’s role in tackling such issues and questions, including the Cats’ Cupboard and more.

Poetry provides a conduit for engaging readers in fostering feelings and understandings. Food, creativity, language, and words all play a significant role in our lives and relationships. In the latest episode of Something to Chew On, Traci Brimhall, professor in the Department of English at K-State and Kansas Poet Laureate, shares about her passion for poetry and food. She draws a connection between the two and shows that the humanities – including poetry – fit into so many places within the food system.

How do we maintain relevant information on public health in the arena of local food producers? Is there a connection between food security and food safety? How do we make information on mitigating these challenges available? In this podcast, we will discuss these issues and more with Londa Nwadike, Extension Associate Professor of Food Safety for Kansas State University and the University of Missouri. With a rich background in the international food system along with a passion for food safety and human wellbeing, Nwadike shares her insight into today’s challenges with food quality and availability.

The agriculture industry has advanced in many positive ways, including increases in productivity and efficiency, but the cost of those advancements could be high. Current research in agronomy is seeking ways to manage food production that will feed an ever increasing population with improved efficiency, productivity and nutritional value. Ignacio Ciampitti, professor of agronomy at Kansas State University, is working with colleagues — both inside and outside of the college of agriculture — and is encouraging students to broaden their view of agronomy due to the increasing need for a multidisciplinary approach to solving problems. He joins the podcast and takes us through his passion and vision for improving the future of agronomy and food production around the world.

The sustainable production of beef cattle and other animal protein is complex, and the achievement of ‘net zero’ production from an environmental perspective is challenging at best, making it difficult to know where to begin. Areas of focus in this field include using food waste streams as quality animal feed, gathering all the areas of expertise need to tackle sustainability, impacting the microbiome of feed and reducing greenhouse gases. Phillip Lancaster, clinical assistant professor and member of the Beef Cattle Institute at Kansas State University, joined “Something to Chew On” to discuss the work he is doing to tackle these issues.

The study of cereal grains comes in many forms, from the fundamental investigation of grain components and their functionality, to processing technologies, to the development of healthy food products ready for consumption. In this podcast, we welcome Sajid Alavi, professor of grain science and industry, to discuss the importance of cereal grains research in the sustainable production of grain-based foods that represents close to 70% of the world’s calorie consumption.

When a mechanical engineer, a microbiologist and a food scientist collide, big things happen in a very small way. The old adage, “it takes a village,” appropriately describes the importance of an interdisciplinary approach to solving food challenges. In this podcast we talk with Dr. Shih-Kang "Scott" Fan, professor of mechanical engineering at Kansas State, about his work on the development of a “lab on a chip” using microfluidics in the identification of STEC producing e-coli and other pathogenic organisms.

The country of Ukraine is a major worldwide producer of cereal grains and cooking oils. The recent Russian invasion of Ukraine has put food security at risk for many parts of the world. Our guest for this episode is Antonina Broyaka, former dean of the faculty of economics and entrepreneurship at Vinnytsia National Agrarian University in Ukraine. Following the Russian invasion of Ukraine, Broyaka came to the United States as a refugee with her two children and is now an extension associate of the department of agricultural economics at Kansas State University. Her focus here at K-State is on the economic impact of the Russian military aggression on both Ukrainian agriculture and global food security.

This summer, 24 recipients from the 2022 Mandela Washington Fellowship for Young African Leaders program joined K-State faculty in learning about leadership in civic engagement. In this episode, we are pleased to welcome one of those participants, Saykwayee Harmony Henry from the Republic of Liberia. Saykwayee is a mother, public speaker, entrepreneur, advocate for the rights of women and children and is the executive director at Kids Development Initiative. Children in Liberia go to school hungry while companies from other countries use Liberian land to grow and export crops around the world. The heart of Saykwayee’s work focuses on agriculture development and her country’s need to produce food for themselves through practical education and prioritizing healthy food production as a lifestyle and profession from a very young age.

This podcast episode features a team of K-State lipid researchers to help us understand food through basic lipid research and how this work improves what we eat. For this conversation, we welcome Ruth Welti, distinguished professor of biology and director of the Kansas Lipidomics Research Center; Kathrin Schrick, associate professor of biology; and Timothy Durrett, associate professor of biochemistry and molecular biophysics.

In this podcast, Jeongdae Im, Jeffrey and Joy Lessman keystone research scholar and assistant professor in the Department of Civil Engineering discusses destructive greenhouse gases in the food system. From hay bales to landfills, plastics to wastewater, the intersection of engineering and microbiological science has allowed Im to tackle multiple challenges in studying ways to mitigate the negative effects of those greenhouse gases.

In this podcast, we talk with Prathap Parameswaran, associate professor in the Department of Civil Engineering at K-State. Parameswaran’s research focuses on the use of anaerobic microorganisms in a continuous system that produces energy and isolates materials that might be used to increase soil nutrients and more. Parameswaran discusses his approach to combating water contamination and its importance within agricultural systems.

In this podcast, we talk with Sonny Lee, assistant professor in the Division of Biology at K-State. Lee’s work touches on many areas of microbiome research and casts a wide net in laboratory studies, mining data from peers to aid in complex evaluations, and working with students and colleagues capable of critical thinking and problem solving. Lee discusses how we are in the infancy of understanding how organisms impact our health, a plant's ability to grow and everything dealing with life as we know it.

Listen to our first podcast of 2022, where we discuss weed management techniques, old and new, and the tools being developed to achieve food crop yield optimization with Vipan Kumar, Ph.D., Assistant Professor in the Department of Agronomy at Kansas State University. Weeds can reduce food crop yields by more than 30%. In this podcast, Kumar discusses the ways in which this problem might be solved when the need for food production will continue to increase, and the challenges caused by climate change create a moving target. Transcript: “Diversity is the key to Sustainability; Challenges and opportunities in the field of Weed Science”. Diversity is the key for sustainability. You keep doing one thing again and again you will see a problem that we have seen in our herbicide based methods or weed control. Something to chew on is a podcast devoted to the exploration and discussion of global food systems. It's produced by the Office of Research Development at Kansas State University. I'm Maureen Olewnik, coordinator of Global Food Systems. We welcome back co host Dr. Jim Stack Professor of Plant Pathology, weeds can reduce food crop yields by more than 30%. These interlopers compete for resources including soil nutrients and water. We attempt to control weed growth through chemistry, but over time they manage to mutate, overcome, thrive, and adjust to given management techniques. So how is this problem solved when the need for food production will continue to increase and the challenges caused by climate change create a moving target. Today, we will hear more about weed management techniques old and new. And the tools being developed to achieve food crop yield optimization with Dr. Vipan Kumar, Assistant Professor in the Department of Agronomy at Kansas State University, I want to welcome you Vipan would like to before we get started in the technical side of things, just get a little background and understanding of who you are and how you got to the place that you are today as far as your professional interests go. Sure, So my name is Vipin Kumar, I'm originally from India. I did my bachelor in crop science, but finished in 2008 from Punjab Agricultural University back in India, in the state of Punjab, it's a Northwestern State in India, mainly known for wheat production and rice production. And it's very big in ag, Punjab state. So, my original goal was to help communities there, especially the farming communities to management practices they are doing so I did my bachelor there. And then I started my master actually mastering Weed Science in Pau 2008, fall 2008. But somehow I was also interested to come abroad and expand my education here in the States. So I was looking through some programs and during that time, I got to know there is a master positions open in Louisiana State. So I I applied there and I got invited and came over 2009 That was summer 2009 started my graduate research assistant with LSU, Louisiana State, Louisiana State University. So that program was specifically looking for someone who can help growers in terms of managing their irrigation water irrigation scheduling, developing some crop coefficients for the cotton prop in North East side of Louisiana. So I was based in actually a research center. It was in North East Louisiana, about five, four or five hours from the main campus Baton Rouge. So my whole research was on resource center and I got to know very few people there but I had a very excellent project to work with. So during that time, I was doing a master I got interested in Weed Science because wonderful. One of my committee member was a weed scientist. He was the superintendent with the research center and he was on my committee and glyphosate resistant Palmer Amaranth was kinda getting a lot of attention during that time in codon. So during that conversation and meeting with his students, I got interested in wheat science. So finishing master and then I started applying for PhD...

In this episode, we host Dr. Philip Hardwidge, associate director of the Center on Emerging and Zoonotic Infectious Diseases in the Department of Diagnostic Medicine and Pathobiology at Kansas State University. Dr. Hardwidge’s research focuses on understanding, treating and preventing diarrheal disease caused by bacterial pathogens. These pathogens represent important threats to food safety, biosecurity and animal health. His research team is tackling the fundamentals of biochemical interactions, leading to a better understanding of mitigation methods. Transcript: The Many Paths of Pathogens with Dr. Philip Hardwidge, associate director of the Center on Emerging and Zoonotic Infectious Diseases We have to be as scientists extremely open and and generally willing to share data be transparent about our raw data and like other aspects in life know when to ask for help. [Music] Something to chew on is a podcast devoted to the exploration and discussion of global food systems produced by the Office of Research Development at Kansas State University. I'm Maureen Olewnik. Coordinator of Global Food Systems. I'm Scott Tanona. I'm a philosopher of Science. We welcome back co-host Dr. Jim Stack Professor of Plant Pathology. Diarrheal disease caused by bacterial pathogens is a challenge in both humans and animals in many instances the introduction of pathogens in animal systems causes illness and in some cases is carried through meat processing affecting contamination of food meant for human consumption. Studies of food safety at K-State includes fundamental through applied research. The importance of research in the area of pathogenic bacteria has been addressed in several of our podcasts to date. Most focusing on the applied research in testing, monitoring, and mitigating potential contamination of food products. However, the basic molecular biology of host pathogen interaction is not well understood. In today's podcast, we will talk with Dr. Philip Hardwidge, Associate Director of the Center on Emerging and Zoonotic Infectious Diseases here at K-State. His study of host pathogen interaction has led to a better understanding of the mechanisms by which pathogens enter and colonize in a host system. With studies leading to an understanding of how this impacts autoimmune disorders, cancer, and more. I would like to welcome Dr. Philip Hardwidge to the podcast. Dr. Hardwidge is the Associate Director of NIH and Cobra Center on Emerging and Zoonotic Infectious Diseases. I am hopeful that he will explain to us exactly what all that means. Before we get started in talking about your current activities, Dr. Hardwidge could we maybe get a little bit of understanding of who you are, what your background is, and what brought you to K-State. What brought you to the area of study that you're in, today. Thanks for having me on this podcast series. I'm from the midwest, Michigan and Illinois. My father was a Pfizer scientist and we happened to be living in Central Illinois when I was a high school student, so he gave me some interest in Microbiology and Chemistry, so I ended up doing a Microbiology degree at the University of Illinois, and wanted to develop a research program kind of at the interface between Biochemistry and Microbiology, so I knew from a fairly early age where my career would hopefully head. I did a PHD at the Mayo Clinic Graduate School in Rochester, Minnesota. So, Mayo is a very famous hospital. They also have a very robust graduate training program. And after that, I did a postdoc at the University of British Columbia in Vancouver Canada. Primarily because one of the leading E Coli Microbiologists was running his laboratory in Vancouver and when I finished my education I took an Assistant Professor Position in South Dakota State University back in 2005. There were some unique opportunities to help develop their graduate program, and I had the opportunity to work with germ-free piglets which are a very...

In celebration of World Food Safety Day, this week we are joined by researchers from the Food Science Institute at Kansas State University: Sara Gragg, associate professor; Randall Phebus, professor; Carla Luisa Schwan, postdoctoral fellow; and Jessie Vipham, assistant professor. World Food Safety Day aims to draw attention to foodborne risks and inspire action to prevent, detect and manage risks. This important work contributes to food security, human health, economic prosperity, agriculture, market access, tourism and sustainable development. The World Health Organization and the Food and Agriculture Organization of the United Nations jointly facilitate the observance of World Food Safety Day, in collaboration with member states and other relevant organizations. This international day is an opportunity to strengthen efforts to ensure that the food we eat is safe, mainstream food safety in the public agenda and reduce the burden of foodborne diseases globally. Transcript: [Music] Something to chew on is a podcast devoted to the exploration and discussion of Global Food Systems produced by the Office of Research Development at Kansas State University. I'm Maureen Olewnik. Coordinator of Global Food Systems. World Food Safety Day is June 7, 2021. This is a day to reflect on the importance of safe and sustainable food, heed the work being done at K-State, and around the world on advancing an understanding of cause and control of food safety issues, and look toward better nutrition through safe food worldwide. Today we are excited to share with you a panel of food safety experts that work with interdisciplinary teams in the Food Science Institute here at K-State. Food safety is a major area of research in the Food Science Institute , including animal and plant-based foods. Through outreach to colleagues here at K-State, nationally and internationally, the Food Science Institute 's research team has tackled some of the most challenging food safety problems. From testing in our Biosecurity Research Institute, biocontainment bsl3 facilities, to helping teach consumers in developing regions of the world the basics of handling and preparing safe food. We welcome back co-host Dr. Jim Stack Professor of Plant Pathology, and welcome to our panel of experts Dr. Sara Gragg, Dr. Randall Phebus, Dr. Carla Luisa Schwan, and Dr. Jessie Vipham. World Food Safety Day is a great time to focus on the work being done at K-State in the area of food safety through the Food Science Institute. We're going to take a bit of a different tact on this podcast by welcoming a panel of scientists that have made food safety their professional passion. They will share with us a vision of food safety research carried out at K-State, and explain how K-State is participating in the recognition of this notable day. I'd like to welcome back to the podcast doctors: Jessie Vipham, Dr. Randall Phebus, and Dr. Sara Gragg and first time welcome to Dr. Carla Schwan. Give us a little background on what the 2021 World Food Safety Day is, and where K-State fits into that? Yeah, this is a really exciting endeavor that is led out of the World Health Organization and the Food and Agriculture Organization of the United Nations, and it was actually envisioned and put into play back in 2018, so we haven't, I don't think, as a university, here at K-State, participated in the past. But we saw this, the date is June the 7th, it's always every year, June the 7th, and the FAO has asked people to participate, and they've given some guidelines on things that we could do. And to highlight some of the food safety work that we're doing here at K-State, which is pretty extensive. The aim of World Food Safety Day, according to the FAO is to draw attention and inspire action to help prevent, detect, and manage foodborne risk. As we know, it's not just the health aspect of foodborne risk, but it's also how food safety contributes to food security, and human health, and economic...

This week, Dr. Sara Gragg, associate professor of food science in the Department of Animal Sciences and Industry, discusses how and where pathogens access meat. The study of E. coli, salmonella and other toxin-producing pathogens has been a major focus of researchers at Kansas State University for many years. Gragg has presented extensively on the topic of food safety and studies processes in food safety and microbiology. Her research program investigates pre- and post-harvest issues affecting the meat and produce industries, with specific interests in addressing how pathogens contaminate food products and the application of interventions to prevent or reduce pathogen presence. Transcript: [Music] Something to Chew On is a podcast devoted to the exploration and discussion of Global Food Systems produced by the Office of Research Development at Kansas State University. I'm Maureen Olewnik, coordinator of Global Food Systems. And I'm Colene Lind, Associate Professor of Communication Studies at Kansas State. I studied the public's role in science and environmental policy. And I'm Jon Faubion. I'm a food scientist. The safety of the food we eat is important to everyone. Studies of food contamination with E coli, salmonella and other toxin producing pathogens has been a major focus of research at Kansas State University for many years. Questions on pathogenic contamination in meat and how the organism enters into that food system are at the center of research activities in several disciplines. Today's guest is Dr. Sarah Gragg, associate professor in the Department of Animal Science and Industry at Kansas State University. Her research program investigates pre harvest and post harvest issues affecting the meat and produce industries with specific interests in addressing the manner by which pathogens contaminate food products, and the application of interventions to prevent and or reduce pathogen presence. She is particularly interested in studying the pre harvest transmission of foodborne pathogens in food animals, as well as investigating interventions to reduce foodborne pathogens in live animals. I would like to welcome Dr. Sarah Gragg to the podcast, something to chew on. We're looking forward very much to having a discussion with you here today. Before we get started on some of the technical side of what you do, can you give us a bit of background on yourself, who you are, and how you got interested in the work that you do? Yes, absolutely. My pleasure. Thank you, Maureen. And thanks to the entire team for inviting me today. I really enjoy the opportunity to be here with you and visit with you about my passion, which is food safety. So with that I'll share a little bit about how I came to be a food safety researcher. I was actually in high school and walked into my Agriculture class as a freshman didn't know what to expect. And we had a new teacher that year. His name was Todd Berkshires and he was starting us off on our Agriculture classes but also in taking our FFA program forward as well. We had a co-advisor, as well, in our FFA program. And so I got to know these two teachers interacted with Todd Berkshires the most and as part of FFA, we have to have something called a supervised agricultural experience program or an SAE for short. And, I grew up right outside of Lincoln, Nebraska. And I had like two or three acres and had some close friends that I also would show and train horses with, and so, I was definitely a part of agriculture but I wasn't per se the traditional farm kid if you will. And so, I didn't know what I was going to do for my SAE program. And his wife, Dr. Mindy Berkshires was a brand new assistant professor at the University of Nebraska Lincoln at the time. And he said why don't you go work with her in the lab because food science and technology is actually an SAE emphasis area. And we can see if maybe that's something that you want to do. And I said that sounds fantastic. And so I got...
