  • The downstream effects of disasters on food supply chains

    The downstream effects of disasters on food supply chains
    Mar 6 2026
    It seems like the frequency of weather-related disasters is increasing. Across the US we're seeing wildfires, tropical storms and hurricanes, extreme heat, extreme cold with snow or ice. And torrential rain leading to a loss of property, life, and livelihoods. What's more, similar extreme events are happening across the globe. These disasters all can have an impact on our food supply and the ability of people to access food. Today, we're speaking with environmental sustainability management expert, Betsy Albright, who is an associate professor of the practice at Duke University's Nicholas School of the Environment. Betsy's research centers on how policies and decisions are made in response to weather related disasters. Interview Summary Betsy, I've been wanting to have you on the podcast for a while, so I'm excited to get you now. So, let's begin with the first broad question. I'd be really interested to learn a little bit more about your research to make sure that our listeners are up to date on it. And I know you really study disasters, but could you explain or expand on what that really means for our listeners? I'm an environmental social scientist who studies the human and social side of disasters. And I ask questions about how climate related disasters or climate driven disasters, or weather disasters affect communities and households. And how individuals perceive risks from disasters, how they're affected by disasters, how they learn from make changes and adapt after disasters. My work started with my dissertation in central Europe. I had a Fulbright in Hungary. But from then I've expanded and moved most of my work to the US context. And our research team and I have done work on flooding and wildfires in Colorado, hurricanes in North Carolina. And I'm also working on a study of the flows of disaster assistance funds from FEMA to communities. And all of this is with or through a lens of equity or inequities and thinking about that across the disaster cycle. This is really important, and I remember being at a conference with you and learning about your work. And I was struck by what happens after the disaster. And in particular what happens to availability of food. And I work with the food bank here in North Carolina. And one of the things I know is when there is a disaster, like when Helene hit Asheville, there are real challenges in getting food out to people. Does your work touch on those topics as well? Yes. I would not say that our work centers on food, but food definitely intersects across all phases of the disaster cycle from preparing for disaster, experiencing disaster, the immediate response- that food bank getting food out- to long term recovery and thinking about risk mitigation. And we can think about that, you know, through a number of different lenses. Both on the food access side, but also on the food systems agriculture side as well. As I mentioned earlier, I take an equity lens on much of the work that we do. It's really important to recognize that disasters hit unevenly across society, across the landscape. Disproportionately they magnify social and environmental stressors that are already there. Communities with limited access to wealth, limited access to food, who are underserved, rural communities, racialized communities, often experience greater impacts from disasters. Disasters occur on top of histories of disenfranchisement. For example, centuries of marginalization of the minoritized Romani peoples of Central Europe they've seen great impacts from flooding. And in North Carolina, Black and African American communities whose ancestors were enslaved and suffered land loss through racist systems of who gets access to loans, access to land ownership. And because of these systems and processes, communities, families, individuals may live on marginal lands, may not own their lands. Their lands may be more prone to flood risk. May be underserved. Their housing may be more at risk. They may rent and not own. May have less agency and resources to repair their homes. And may have less trust in government and government systems. So really thinking about all of that, and then piling on disasters over these centuries of marginalization, disenfranchisement, underinvestment is really critical when trying to disentangle all these processes and develop policy solutions. This is really fascinating work and so thank you for laying out the sort of reality of the experience of disasters where people who have been marginalized may have difficulty accessing resources or there may be some concerns about trust. Broadly, we're interested also in the food system, and I'd be interested to understand how, when disasters strike, do you see effects upon the food system or the food system responding to these disasters? Recognizing that some individuals have higher food stress, even without a disaster, they may have higher pollutant burden because they live next to a concentrated animal feed lot operation...

  • Pathway to Market is Complicated for Cell-Cultivated Protein

    Pathway to Market is Complicated for Cell-Cultivated Protein
    Feb 24 2026
    As global demand for meat grows, this episode of Duke University's Leading Voices in Food podcast examines cell-cultivated protein—real meat grown from animal cells—and the evolving U.S. policy landscape shaping its future. Host Norbert Wilson (Duke World Food Policy Center) speaks with postdoctoral researchers Kate Consavage Stanley (Duke/Bezos Center for Sustainable Proteins) and Katariina Koivusaari (NC State/Bezos Center) about their article in Trends in Food Science and Technology on U.S. regulatory and legislative activity. The conversation explains the joint FDA–USDA regulatory approach for cell-cultivated meat (FDA oversight through cell cultivation; USDA oversight from harvest through processing, packaging, and labeling) and FDA oversight for cell-cultivated seafood (except catfish). They discuss timelines companies report for approval (often two to three years), the lack of federal public guidance on naming and labeling so far, and how USDA label approvals are currently handled case by case (e.g., "cell-cultivated chicken" and "cell-cultivated pork"). The episode also covers state-level labeling laws and the likelihood of federal preemption if state requirements conflict with federal statutes, as well as a growing wave of state restrictions and bans—Florida and Alabama in 2024, followed by Indiana, Mississippi, Montana, Nebraska, and Texas in 2025—plus funding restrictions in South Dakota and Iowa. The guests explore implications for consumers, interstate commerce, innovation, investment, and U.S. leadership, noting ongoing lawsuits in Florida and Texas and continued legislative activity such as a proposed ban in Georgia. Interview Transcript Kate, let's begin with you. In the paper, you write about the regulatory frameworks that have been developed for cell-cultivated meat and seafood products in the US. To start, let's talk about what's unique about cell-cultivated products from a regulatory standpoint and how the US Department of Agriculture and US Food and Drug Administration have decided to handle cell-cultivated protein products. Kate - Yes, so as you mentioned in the introduction, Norbert, cell-cultivation is a new technology for use of the food supply. So, the US government had to adapt its existing legal frameworks for food safety regulation. As your listeners may already know seafood is regulated by the FDA, so it was within their scope to also regulate cell-cultivated seafood. The FDA therefore regulates all cell-cultivated seafood products with the exception of catfish. When it came to determining the regulatory approach for cell-cultivated products from livestock, poultry, and catfish, it was a bit more nuanced as the processes and components evolved fell under both USDA and FDA purview. In 2019, the FDA and USDA therefore agreed on a joint regulatory approach where the FDA regulates the early stages of the cell cultivation process, including when those cells are taken from the animal, grown in the bioreactor, and matured into specific cell types such as muscle or fat cells. At the point where those cells are ready to be harvested from the bioreactor to use in a food product, oversight transfers to USDA who oversees that harvesting process as well as food processing, packaging, and labeling. I know this joint regulatory approach may sound complicated, but it's important to note that USDA and FDA already coordinate oversight over other foods in the food supply. I'll give you an example that we all love pizza. A frozen cheese pizza is regulated by the FDA, whereas a frozen pizza with meat toppings like pepperoni is regulated by the USDA. It is therefore not unprecedented that FDA and USDA would agree to jointly regulate cell-cultivated products. And while the process is new, the products go through the same safety checks as other foods in the food supply. In the past few years, we've seen four cell-cultivated meat products go through the joint USDA-FDA regulatory process, meaning they can be sold in the US food supply. And one cell-cultivated seafood product has gone through the FDA regulatory process. Kate, thank you for sharing this. And I've used a pizza example in my class, and it is super complex this regulatory maze that we're talking about. It seems like there has been a lot of collaboration between these two agencies, and so that's important to hear. But it is also the case that it seems challenging for cell-cultivated protein companies to get through this process. Is this a fair assessment and would you elaborate? Kate - Yes, absolutely. We've heard from cell-cultivated companies that it can take two to three years to get through this process. And there certainly is a lot of back and forth between the companies and FDA and USDA. Great, thank you. Katariina, now let's turn to you. How do these regulations extend to labeling and what do we know about the federal government's approach to labeling the sale of cultivated products thus far? Katariina – So, ...

  • E290: Grading the Biggest US Grocery Stores on Healthy Offerings

    E290: Grading the Biggest US Grocery Stores on Healthy Offerings
    Jan 15 2026
    Do you ever wonder whether your grocery store cares about whether you have a healthy diet? Every time we shop or read advertisement flyers, food retailers influence our diets through product offerings, pricings, promotions, and of course store design. Think of the candy at the checkout counters. When I walk into my Costco, over on the right there's this wall of all these things they would like me to buy and I'm sure it's all done very intentionally. And so, if we're so influenced by these things, is it in our interest? Today we're going to discuss a report card of sorts for food retailers and the big ones - Walmart, Kroger, Ahold Delhaize USA, which is a very large holding company that has a variety of supermarket chains. And this is all about an index produced by the Access to Nutrition Initiative (ATNi), a global foundation challenging the food industry investors and policy makers to shape a healthier food system. The US Retail Assessment 2025 Report evaluates how these three businesses influence your access to nutritious and affordable foods through their policies, commitments, and actual performance. The Access to Nutrition Initiatives' director of Policy and Communications, Katherine Pittore is here with us to discuss the report's findings. We'll also speak with Eva Greenthal, who oversees the Center for Science in the Public Interest's Federal Food Labeling work. Interview Transcript Access ATNi's 2025 Assessment Report for the US and other countries here: Retail https://accesstonutrition.org/index/retail-assessment-2025/ Let's start with an introduction to your organizations. This will help ground our listeners in the work that you've done, some of which we've spoken about on our podcast. Kat, let's begin with you and the Access to Nutrition Initiative. Can you tell us a bit about the organization and what work it does? Kat Pittore - Thank you. So, the Access to Nutrition Initiative is a global foundation actively challenging the food industry, investors, and policymakers to shape healthier food systems. We try to collect data and then use it to rank companies. For the most part, we've done companies, the largest food and beverage companies, think about PepsiCo, Coca-Cola, and looking are they committed to proving the healthiness of their product portfolios. Do the companies themselves have policies? For example, maternity leave. And these are the policies that are relevant for their entire workforce. So, from people working in their factories all the way up through their corporate areas. And looking at the largest companies, can these companies increase access to healthier, more nutritious foods. One of the critical questions that we get asked, and I think Kelly, you've had some really interesting guests also talking about can corporations actually do something. Are corporations really the problem? At ATNi, we try to take a nuanced stance on this saying that these corporations produce a huge amount of the food we eat, so they can also be part of the solution. Yes, they are currently part of the problem. And we also really believe that we need more policies. And that's what brings us too into contact with organizations such as Eva's, looking at how can we also improve policies to support these companies to produce healthier foods. The thought was coming to my mind as you were speaking, I was involved in one of the initial meetings as the Access to Nutrition Initiative was being planned. And at that point, I and other people involved in this were thinking, how in the world are these people going to pull this off? Because the idea of monitoring these global behemoth companies where in some cases you need information from the companies that may not reflect favorably on their practices. And not to mention that, but constructing these indices and things like that required a great deal of thought. That initial skepticism about whether this could be done gave way, at least in me, to this admiration for what's been accomplished. So boy, hats off to you and your colleagues for what you've been able to do. And it'll be fun to dive in a little bit deeper as we go further into this podcast. Eva, tell us about your work at CSPI, Center for Science in the Public Interest. Well known organization around the world, especially here in the US and I've long admired its work as well. Tell us about what you're up to. Eva Greenthal - Thank you so much, Kelly, and again, thank you for having me here on the pod. CSPI is a US nonprofit that advocates for evidence-based and community informed policies on nutrition, food safety and health. And we're well known for holding government agencies and corporations to account and empowering consumers with independent, unbiased information to live healthier lives. And our core strategies to achieve this mission include, of course, advocacy where we do things like legislative and regulatory lobbying, litigation and corporate accountability initiatives. We also do policy and ...
