You must handle onions with black mold carefully.
The American USDA guidelines say you can completely peel off the dried outer layers if they have black mold, and safely use the good part inside.
But you must throw the whole onion away if the mold goes deep inside and makes the onion soft, watery, or rotten.
Do not think about the money you spent on buying them. Throwing away a rotten, moldy onion is much safer than eating bad food and ending up in a hospital.
People with allergies or asthma can face sneezing, coughing, and breathing issues if they inhale these black mold spores.
People with very low immunity can rarely get fungal infections like Aspergillosis.

Is this the Black Fungus disease?
Do not confuse this black mold with the deadly Black Fungus disease called Mucormycosis.
The CDC and WHO confirm that Mucormycosis fungi usually live in soil, dust, and rotting plants in the environment.
So, the black mold on your onion is not the same fungus that causes Mucormycosis.
