In product safety labeling, what does contamination refer to?

• A. Brand recognition
• B. Impurities introduced during processing
• C. Packaging color
• D. Production cost

Answer: (B)

Contamination in product safety labeling means the presence or introduction of impurities or unwanted substances into a product during processing, handling, or packaging. These impurities can be biological (like bacteria or mold), chemical (residual cleaners or solvents), or physical (foreign objects such as metal or glass). Such contamination creates safety risks and is what labeling aims to address, potentially prompting warnings, allergen information, or recalls. The other options don’t fit because brand recognition, packaging color, and production cost are attributes related to marketing or economics, not the presence of unwanted substances in the product.
