The history and origin of the National Moldy Cheese Day are not known. This day encourages people to consume colored moldy cheeses like Roquefort, camembert, brie bleu, gorgonzola, Maytag blue, Gorgonzola, Stilton, and Roquefort.

Cheese is produced by coagulation of the milk protein ‘casein’ in a wide range of flavors, textures, and forms. The bluish-greenish hues of the blue cheese are caused by Penicillium roqueforti or Penicillium glaucum added to the milk or curds. The mole spores grow and spread with the help of small holes that are hit into the cheese.

The molds in cheese are completely safe to eat. These molds are responsible for producing a large number of varieties of cheese. They are also the reason for the unique flavor of the cheese. Blue cheeses are often considered “the moldiest” of all cheeses and also have a more distinct smell.
