Which term denotes visible signs of contamination or spoilage in foods, such as abnormal color, texture, or odor?

• A. Spoilage
• B. Visible Contamination
• C. Cross-contamination
• D. Fermentation

Answer: (B)

Visible signs that food has degraded are called spoilage. Spoilage refers to the deterioration of quality—changes in color, texture, or odor—caused by microbes or chemical reactions, and these changes indicate the food may be unsafe to eat. Visible contamination, by contrast, means you can see foreign matter on the surface, like dirt or hair, which is not about internal changes in the food itself. Cross-contamination is the transfer of contaminants from one surface or food to another, and fermentation is a specific microbial process that alters food but isn’t the general term for spoilage signs. So the best term for those visible signs of spoilage is spoilage.
