The driving force behind a good banana bread is the browned, nearly spoiled bananas that are its namesake. Using these overripened bananas to lend sweetness and intense banana flavor is perfectly acceptable, while eating spoiled banana bread can make you sick. Look for signs of spoilage such as mold and discoloration, and store your banana bread appropriately to prevent spoilage.

Banana Bread Gone Bad

Signs of spoilage in banana bread include mold, discoloration and off-odors; discard any old banana bread with these qualities. However, if you store your banana bread properly, this will not be a problem, as banana bread is shelf stable for a short time and can be held in the refrigerator or freezer for longer storage. Banana bread will last unrefrigerated for up to two days and refrigerated for one week. Always wrap banana bread in plastic wrap or another air-tight storage container to prevent it from drying out; while the texture may be undesirable when banana bread becomes dry, being dry alone does not indicate spoilage.
