3. Safe consumption guidelines: If the blue cheese develops excessive mold that is furry, discolored, or creates an off-putting odor, it’s best to discard it.

However, the blue veins and the white or pale yellow marbling found in blue cheese are perfectly safe and can be consumed without hesitation. What does blue cheese look like?

Blue cheese has a distinct appearance that sets it apart from other cheeses. Here are a few characteristics that define its look:

1.

Blue veins: The most prominent feature of blue cheese is the blue or green veins that run through the cheese. These veins are the result of the mold culture injected during the cheese-making process.

Depending on the variety, the veins can vary in thickness, density, and color intensity. 2.

Mottled coloring: Blue cheese often has an uneven, mottled appearance. The color ranges from pale white to creamy yellow.

Some varieties may have a grayish or bluish hue due to the penicillium mold. 3.

Rind variations: Blue cheese can have different types of rinds. Some varieties have a natural rind formed during the aging process, which can be firm and brownish.
