What are common signs of food spoilage?

1. Bright colors and firm texture

2. Off-odor, discoloration, and changes in texture

3. High viscosity and strong taste

4. All of the above

The correct answer is: Off-odor, discoloration, and changes in texture

Off-odor, discoloration, and changes in texture are all key indicators of food spoilage because they signal that microbial activity or chemical reactions have altered the food’s quality and safety. Off-odor occurs due to the production of gases by bacteria as they break down food. Discoloration can indicate oxidation or the growth of mold or other microorganisms, leading to an unfit food product. Changes in texture, such as mushiness or sliminess, can also signify that food is no longer safe to consume. These signs are critical for food safety, as they help identify food that has gone bad and may pose health risks if consumed. Bright colors and firm texture typically suggest freshness and quality, while high viscosity and strong taste are not standard indicators of spoilage. Thus, the correct identification of spoilage signs is essential for ensuring food safety in handling and consumption.
