Sadly, there's a risk of salmonella and staph growing in food kept in fireless cookers for too long, or in less than ideal circumstances (i.e., non-perfect climates or less than incredible hygiene). Bettina must have removed the food the instant it was done and cleaned everything wildly. Either that or she and Bob died after the book was over.

EEEEE! She puts salt and "salad dressing" and LETTUCE in peanut butter sandwiches. She is OF THE DEVIL!
