What is a key sign of food spoilage?

A key sign of food spoilage is an off smell. When food begins to spoil, chemical changes occur that often produce unpleasant odors. These odors are an indication of the growth of bacteria, molds, or yeasts, which can make food unsafe to consume. It's essential for food service workers to recognize these indicators, as consuming spoiled food can lead to foodborne illness.

In contrast, bright color, crisp texture, and normal size generally suggest that food is fresh and in good condition. Bright colors can indicate ripeness and optimal quality, while a crisp texture typically suggests freshness. Additionally, normal size is associated with food quality, as poorly grown or overripe items might not maintain their expected size and shape. Recognizing an off smell is crucial in food safety practices to prevent health risks associated with spoiled food.
