How could a quick trip after work to Trader Joe’s turn into a public health crisis? In this episode we investigate the 2013 E. coli outbreak linked to Glass Onion Catering’s prepackaged salads.  How did the intersection of contaminated water, industrial farming, and regulatory loopholes create such a deadly outbreak? More importantly—who was supposed to protect us, who failed us, and how could it have been prevented? In 2013 a simple salad purchase turned into a public health disaster. Across four states on the West coast, thirty three people fell ill and seven of them were hospitalized due to an outbreak of E. coli O157:H7 linked to pre-packaged salads sold as Trader Joe’s. Despite the food safety laws designed to prevent incidents like these, failures at multiple levels from agricultural water testing, to processing plant sanitation, to supply chain oversight—this deadly bacterium was allowed to slip through the cracks.  This episode delves into the complex journey of contamination. It begins in the farm fields of Modesto, CA, where antibiotic-laden runoff from industrial cattle farms might have seeded dangerous bacteria into irrigation water. We unpack how industrial farming practices and weak regulatory enforcement turned leafy greens into a recurring vehicle for deadly outbreaks.  A deep dive into the Food Safety Modernization Act (FSMA), the evolution of antibiotic-resistant bacteria, and the hidden risks of modern food production reveal the systemic flaws that are still putting consumers at risk. Why does E. coli keep popping up in our fresh product? How can we fix a food system setup to prioritize efficiency over safety?  Join us as we uncover the biological, political, and economic forces that shape our modern food supply as well as what it means for the future of food safety in the United States.  Produced by Ayesha Ashraf  and Anushka Samirah  These podcast episodes were created by members of the 2025 Winter Capstone course in the Human Biology and Society major at UCLA's Institute for Society and Genetics (<a href="https://socgen.ucla.edu/">https://socgen.ucla.edu/</a>).
