I often bring food with me when I’m on the road, such as energy bars, dried fruit, and nuts. But during a recent trip to Pennsylvania (Philadelphia) and New Jersey (Princeton and Freehold), I also picked up a peanut butter and jelly sandwich. I ended up driving around with that sandwich, wrapped in a paper bag, for three days in humid 90 degree weather with no refrigeration. I occasionally looked at the bag as time went on, and imagined the sandwich getting moldy and rancid in the heat. I started thinking I’d have to throw it away. I can only imagine what a ham, beef, chicken, fish, or egg salad sandwich would look like (and smell like!) unrefrigerated in the heat for three days! Finally, I cautiously unwrapped the peanut butter and jelly sandwich. And to my delight, it was in good shape and very edible. No wonder some hunger relief organizations, like Food Not Bombs, focus on providing plant foods, not animal foods, to limit the risk of making people ill.
