What is a key consideration for protecting stored products during pesticide use?

• A. Keep storerooms sealed during treatment.
• B. Only use outdoors.
• C. Ventilate the area after treatment and keep storerooms sealed.
• D. Store pesticides near food.

Answer: (C)

Protecting stored products during pesticide use relies on keeping vapors and residues away from those products. Ventilating the area after treatment helps to remove lingering pesticide vapors, reducing the chance that residues settle on packaging, shelves, or the products themselves. Keeping storerooms sealed during and after treatment acts as a barrier to any drift or vapor that could otherwise enter the storage space and contaminate food, feed, or packaging. Used together, these steps minimize cross-contamination and exposure to stored products.

Sealing without ventilation can trap fumes, increasing the risk of contamination. Ventilating without sealing can allow vapors to reach storage areas more easily. And storing pesticides near food is inherently risky because it creates a direct route for contamination.
