What is "blooming" on chocolate and is it safe to eat?

Chocolate bloom is the whitish film that can discolor the surface of chocolate. It is quite common and is actually the cocoa butter or fat within the chocolate rising to the surface. Bloom is usually caused when the chocolate is exposed to a drastic change in temperature. The cocoa butter separates from the chocolate and rises to the surface creating the “dusty” appearance. Blooming is purely a cosmetic issue and not a safety issue. Bloomed chocolate is safe to eat.
