Which of the following is a chemical hazard?

• A. Glass shard
• B. Foreign object
• C. Pesticide residue
• D. Bacterial contaminant

Answer: (C)

Chemical hazards are substances that can cause harm through their chemical properties when ingested, inhaled, or in contact with the body. Pesticide residue is a chemical hazard because it is a chemical contaminant that can remain on food and potentially cause toxic effects, depending on the pesticide’s toxicity, the amount present, and the level of exposure. Regulations set maximum residue limits to protect health and guide safe levels in foods.

Glass shards and foreign objects are physical hazards—they’re tangible items that can cause injury or choking. A bacterial contaminant is a biological hazard, involving living organisms or their toxins.
