Sandwiches are a quick and easy meal option, but they can also be a breeding ground for bacteria if not handled properly. Mayo is a particularly risky ingredient, as it contains eggs and oil, both of which can support the growth of harmful bacteria. So, how long can a sandwich with mayo sit out before it becomes unsafe to eat? The answer depends on a number of factors, including the temperature of the environment, the type of bread, and the other ingredients in the sandwich.
The Danger Zone:
The danger zone for food is between 40°F and 140°F. This is the temperature range in which bacteria can grow and multiply rapidly. Sandwiches with mayo should never be left out in the danger zone for more than two hours. After two hours, the sandwich should be discarded or refrigerated.
Factors that Affect How Long a Sandwich with Mayo Can Sit Out:
- Temperature: The higher the temperature, the faster bacteria will grow. A sandwich with mayo that is left out in a warm environment will spoil more quickly than a sandwich that is left out in a cool environment.
- Type of bread: Bread that is made with eggs or milk will spoil more quickly than bread that is made without these ingredients.
- Other ingredients: Ingredients that are high in protein, such as meat and cheese, can also support the growth of bacteria. Sandwiches with these ingredients should be eaten sooner than sandwiches with only vegetables.
How to Keep a Sandwich with Mayo Safe to Eat:

If you are planning on eating the sandwich within two hours, you can keep it in a lunch bag with an ice pack.

- Use fresh ingredients: Fresh ingredients are less likely to contain bacteria than ingredients that have been sitting around for a while. When making a sandwich with mayo, be sure to use fresh bread, meat, and cheese.
- Wash your hands: Before making a sandwich, be sure to wash your hands thoroughly with soap and water. This will help to prevent the transfer of bacteria from your hands to the sandwich.
