Science on the Menu: A Food Safety Podcast by EFSA

Forever chemicals are everywhere – but how worried should we be about them? In this episode, we look at the health risks from PFAS, a large group of chemicals used in everyday products, from non-stick cookware to waterproof clothing and food packaging. Together with EFSA expert Hans Steinkellner, we explore why these substances persist in the environment, how they can end up in our food, and what science tells us about their effects on human health. We also examine the challenges of studying thousands of PFAS compounds and what is being done to reduce risks and better understand their impact.

For millennia, humans have selected and improved plants, helping us grow crops that are more productive, resilient and nutritious. But new genetic tools could completely redefine agriculture once more. In this episode, we explore how today’s breeders use tools like “molecular scissors” to edit plant genes more quickly and precisely than ever before. Together with EFSA expert Tommaso Raffaello, we trace the story behind gene editing, unravel the science and safety of new genomic techniques and discover what these advances could mean for the future of food and farming in Europe.

Why are pesticides used and could society do without them? In this episode, we trace the story of agriculture, from its origins to modern day. We meet familiar enemies – pests and diseases – and explore how chemicals are used to control them and keep plants healthy. And we look at how traces can end up in our food - and environment - and what it means for our health and wildlife. Together with EFSA expert Tobin Robinson, we discuss the risks, the science, and the alternatives, from traditional methods to new approaches. And we get up close with an example: the ingredients of an organic pesticide used to protect peaches.

Microplastics are everywhere, from the oceans to our food, but what do we really know about their impact on our health? In this episode, we take a closer look at where microplastics come from, how they end up in food and drinking water, and what happens to them once they enter our bodies. Together with EFSA expert Elena Rovesti, we explore what science can already tell us, why so many uncertainties remain, and what research is under way to better understand the risks linked to microplastics in food.

Science doesn’t end when the research is done. In this episode, we explore why how we talk about science matters just as much as the science itself. From food safety scares and fake news to insects, microplastics and AI, we look at how trust, transparency and audience awareness shape effective science communication. Joined by Barbara Gallani, EFSA’s Head of Communication and Partnerships, we discuss how to translate scientific evidence for different audiences, why perceptions matter, and how clear, coordinated communication helps people make sense of complex food safety issues.
