Today the guys were joined by software developer Daniel Jalkut for a wide ranging discussion on food safety including whether the inside leaves of a head of lettuce need to be washed, whether something can ever be 100% safe, the importance and origins of Mann's Assumption, how what people see in the grocery store informs their perception of food safety, the risks of microorganisms on the outside of food packages, food safety culture, the risks from reheated rice, and a fascinating and deep dive into pine mouth and its causes. The show ends with a discussion about the possibilities of reconditioning a wooden cutting board of unknown origins.
