What describes the legal amount of pesticide residue allowed in or on a raw agricultural commodity?

• A. Containment
• B. Solubility
• C. Tolerance
• D. Viscosity

Answer: (C)

The legal limit on pesticide residues allowed on or in a raw agricultural commodity is called a tolerance. Regulators establish tolerances to protect consumers while still allowing farmers to use pesticides as labeled. Residue levels must stay at or below this tolerance; exceeding it can make the commodity illegal to sell. Tolerances are set by regulatory authorities and are usually expressed in parts per million. If there’s no tolerance for a specific pesticide on a given crop, any detectable residue would be considered illegal. Pre-harvest intervals and proper label-use practices help ensure residues fall within the allowed limit by harvest time. The other terms listed—containment, solubility, and viscosity—do not describe legal residue limits; they refer to containment practices, how a chemical dissolves, and how thick a liquid is, respectively.
