Which of the following could be intentionally added chemicals that may be hazardous if improperly used during food production?

• A. Pesticides
• B. Water
• C. Salt
• D. Sugar

Answer: (A)

Pesticides are chemicals intentionally used to protect crops and stored products from pests, but they can be hazardous if not used correctly. When applied improperly, used in excess, or not allowed to break down before harvest, pesticide residues can remain in food and pose health risks to consumers. That’s why strict regulations exist—maximum residue limits, proper pre-harvest intervals, labeled application instructions, and routine monitoring—to keep residues within safe levels.

Water, salt, and sugar are not typically considered intentionally added hazardous chemicals in the context of pest control or processing; water is essential and can carry contaminants if polluted, while salt and sugar are common, generally safe ingredients. They do not represent the kind of hazard that arises from improper use of an added chemical like a pesticide.
