Black spots on onions? Here’s what you need to know

Black spots on onions are typically caused by fungus or mold. They can also result from damage or improper storage.

Mold grows more easily in conditions with moisture, heat, and humidity. Onions that are bruised or old may also develop black spots.

Purchase firm, dry onions from reliable sources. Store them in a cool, dry, and well-ventilated area, and remove any black spots you find.

Use mesh bags or baskets to allow airflow instead of plastic bags. Keep onions out of direct sunlight and refrigerate any cut onions.

Always choose fresh, firm onions and store them properly to prevent black spots and ensure they are safe and healthy to eat.
