The discussion centers around a recent E. coli outbreak linked to bagged spinach, causing widespread concern and a mass recall of products. Participants express frustration over the lack of clarity regarding the source of contamination, with many questioning how it could not be traced to specific brands or stores. The conversation highlights the challenges in identifying the contaminated spinach, as affected individuals often cannot recall where they purchased it. There is speculation about the contamination occurring during harvesting or processing, particularly in relation to organic farming practices. The outbreak has resulted in a significant reduction in spinach consumption, with some participants joking about their aversion to spinach. The FDA has identified one source, Natural Selection Foods, but acknowledges that there may be additional sources yet to be determined. The discussion reflects a mix of concern for food safety and skepticism about the effectiveness of current tracking and recall processes in the food supply chain.
