Let me start with a caution. This subject—both the food issues and the code issues—might make you queasy. Food safety is an issue that’s of critical importance. In the U.S., food safety is long on data and short on ways to make the data usable. Every few months, we get another multi-state outbreak that reminds us of the safety problems in our food supply and how significant they are. Sadly, these problems are largely inevitable; to keep food costs low as we expect them to be, companies cut corners or import more food from other countries with laxer food-safety laws. Meanwhile, federal regulatory agencies are unable to adequately police an increasingly complex food supply chain. Many people think about food poisoning in terms of meat. There is a reason for this; in 1993, there was a severe outbreak of food poisoning at 173 Jack-in-the-Box restaurants, caused by a relatively novel strain of the E. Coli bacteria (O157:H7). It hospitalized 171 victims and killed 4 people, 3 of whom were small children. Since then, we’ve come to expect regular problems with ground beef. But, meat accounts just only 22% of food poisoning outbreaks; in the past few years, there have been several major outbreaks stemming from cantaloupes, spinach, sprouts, and peanut butter.
