If the outside of a grapefruit is moldy is the inside safe to eat?

If the outside of a grapefruit is moldy, it's best to avoid eating the fruit altogether. Mold can penetrate the skin and contaminate the flesh inside, even if it doesn't appear visibly moldy. Additionally, consuming moldy food can pose health risks, particularly for those with Allergies or weakened immune systems. It's safer to discard the grapefruit if you see mold on the outside.
