Travel Lunches Non-Heat Non-Fridge?

Take it from me: provided it's fully cooked, practically NO food perhaps excepting plain milk will "spoil" or grow bad guys if unrefrigerated for five or six hours. All those old stories about dead-folks-at-the-picnic likely involved HOMEMADE mayo, which is uncooked. Commercial mayonnaise will keep indefinitely without refrigeration. Or at least as long as it takes for one to fix, carry, and eat a sandwich.

Thanks for pointing that out. I think a lot of people freak over this stuff unnecessarily.

In regards to milk, I forgot to put away a gallon jug once. Had just brought it home from the grocery store and left it sitting in the front room for about 5 hours before I remembered. I immediately put it away when I realized. It was fine. However, it did go sour within 5 days - whereas the other jug, which I had put away immediately, stayed good past its expiration date two weeks later.
