Which of the following are chemical contaminants?

Explanation:
Chemical contaminants are substances with chemical properties that can contaminate foods or surfaces. The correct choice lists items that are chemical in nature—cleaners, sanitizers, polishes, and toxic metals—whose residues or leaching can pose health risks if not used or rinsed properly. Bacteria are living organisms and represent biological contamination. Glass shards and hair are physical hazards; they are solid objects that can contaminate or injure but are not chemical substances. In practice, prevent chemical contamination by following label directions for cleaners and sanitizers, rinsing thoroughly, and ensuring metals don’t corrode or leach into food.
