Sarah Sorscher, J.D., MPH, Deputy Director of Regulatory Affairs, Center for Science in the Public Interest.
Did you know that poppy seeds used in baking come from the same plant that produces opiates, including morphine and codeine? Join Food Sleuth Radio host and registered dietitian, Melinda Hemmelgarn, for her interview with Sarah Sorscher, J.D., MPH, Deputy Director of Regulatory Affairs, Center for Science in the Public Interest (CSPI). Sorscher explains that the poppy plant cannot be legally grown in the United States, so all poppy seeds sold in this country are imported. While the seeds themselves contain negligible amounts of opiates, they can be contaminated with plant debris and require washing and processing to reduce opiate contamination to safe levels. Not all importers adequately process their seeds, and some sellers even market poppy seeds as “unwashed” or “unprocessed,” to convey that they have high levels of opiates to consumers who may purchase the seeds to brew poppy seed tea, which can be fatal.

Jonathan Lundgren, Ph.D., Blue Dasher Farm and Ecdysis Foundation, defines and discusses regenerative agriculture.
Did you know that most cropland in the U.S. is characterized by large monocultures, whose productivity is maintained with costly inputs, such as chemical fertilizers and pesticides, and that this over-simplification of our of our food system contributes to climate change, pollution and biodiversity loss? Join Food Sleuth Radio host and registered dietitian, Melinda Hemmelgarn, for her interview with Jonathan Lundgren, Ph.D., Director and Founder of Blue Dasher Farm and the Ecdysis Foundation. Lundgren defines and discusses regenerative agriculture through the lens of research entomologist, agroecologist, farmer, rancher and beekeeper. He shares key polnts from a recent article, “Regenerative agriculture: merging farming and natural resource conservation profitably:” https://peerj.com/articles/4428/. Lundgren explains why pests were 10-fold more abundant in insecticide-treated corn fields than on insecticide-free regenerative farms, and how regenerative farming is at the heart of food system reform.

Suzan Erem, co-founder and Executive Director of the Sustainable Iowa Land Trust describes the “Circle Our Cities” campaign.
Did you know that now is the critical time to facilitate a just transition of land to the next generation of farmers? But the next generation of farmers who want to grow nutritious “table food” cannot afford land that is constantly under pressure from housing development or commodity crops. Join Food Sleuth Radio host and registered dietitian, Melinda Hemmelgarn, for her interview with Suzan Erem, co-founder and Executive Director of the Sustainable Iowa Land Trust (SILT), a statewide non-profit organization that permanently preserves farmland to grow healthy food.

Tristan Brandhorst, Ph.D., Senior Research Scientist, University of WI – Madison discusses his investigation into the toxicity of the commonly used fungicide, fludioxonil.
Did you know that the commonly used fungicide, fludioxonil may cause oxidative damage to human cells? Join Food Sleuth Radio host and registered dietitian, Melinda Hemmelgarn, for her interview with Tristan Brandhorst, Ph.D., Senior Research Scientist, University of WI – Madison who discusses his investigation into the toxicity of the commonly used fungicide fludioxonil. Brandhorst has researched the fungicide’s mechanism of toxicity and its effects on off-target organisms – from earth worms to humans. Brandhorst has been studying the physiology of pathogenic fungi for 20 years with research into fungal metabolites, toxicity factors, and mechanisms of virulence. His research group stumbled upon evidence that the fungicide fludioxonil did not work by its widely accepted “safe” mechanism, and has published his findings that fludioxonil acts on a sugar-metabolizing enzyme common to all cells. His research indicates that the complexity of pesticide effects on cells and enzymes in the body, and organisms generally, are not understood to the extent that they should be. To find out where you might find residues of this fungicide in your food, see The Pesticide Action Network’s What’s On My Food? https://www.whatsonmyfood.org/pesticide.jsp?pesticide=B23.
