Many kitchen staples will survive a power outage. Peanut butter and jelly, relish, mustard, ketchup, soy sauce, Worcestershire, and barbecue sauce are all safe, as are vinegar-based salad dressing.
These items should be discarded if they are open and are held at 50 degrees Fahrenheit or warmer for more than 8 hours:
- Jars of tomato sauce
- Cream-based salad dressings
- Fish sauces
- Mayonnaise
- Tartar sauce
- Horseradish
