Which of the following describes the characteristics of spoiled food?

Spoiled food often exhibits a slimy or sticky texture. This change in texture results from the growth of bacteria, yeast, or mold, which can produce slime as they break down food. When food spoils, it becomes unappealing to consume and can pose health risks due to the presence of harmful microorganisms. The presence of a slimy layer on food can indicate spoilage and should serve as a warning sign that the food is no longer safe to eat.

In contrast, other choices describe characteristics of fresh food. For example, a bright color and firm texture indicate freshness and quality, while crunchy and cold to touch typically represent freshness in produce like vegetables. Lastly, a sweet smell and fresh appearance is a hallmark of good quality food. All these attributes reflect the opposite of spoilage, making them unsuitable descriptors for spoiled food.
