Yes, molds are used to make certain kinds of cheeses and can be on the surface
of cheese or be developed internally. Blue veined cheese such as Roquefort,
blue, Gorgonzola, and Stilton are created by the introduction of P. roqueforti
or Penicillium roqueforti spores. Cheeses such as Brie and Camembert have white
surface molds. Other cheeses have both an internal and a surface mold. The molds
used to manufacture these cheeses are safe to eat.
