Unlike food contaminated with pathogens, the effects of food spoilage can be seen, felt, tasted and smelled. Which statement is true?

• A. True
• B. False
• C. Only seen
• D. Only smelled

Answer: (A)

Spoilage often shows up through sensory cues—what you can see, feel, taste, or smell. Mold growth, off odors, sour tastes, or a slimy texture signal that the food has deteriorated and is no longer of good quality. This is different from many pathogenic contaminants, which can be present even when the food looks, smells, and tastes normal. So you can rely on sensory changes to indicate spoilage, but you cannot rely on them to judge safety from pathogens. That’s why the statement is true: spoilage effects are observable by the senses, while pathogenic contamination may not be detectable this way. In practice, that means discard if spoilage signs are present, and never assume safety based solely on appearance or smell.
