What quality issue should cauliflowers not have in the curd?

The presence of mold or decay in cauliflower curd signifies a significant quality issue as it indicates spoilage or disease that affects both the safety and edibility of the vegetable. Mold growth can lead to the development of toxins, making the vegetable unsafe for consumption. Fresh, high-quality cauliflower should be firm, tightly packed, and free from any signs of mold or rot. These characteristics are essential for ensuring the best flavor, texture, and nutritional value. While discoloration, softness, and overripeness can also indicate quality issues, they do not present the immediate health risk associated with mold or decay, which makes the latter the most concerning quality issue for cauliflowers.
