How long must poison records be kept?

• A. 1 year
• B. 10 years
• C. 2 years
• D. 5 years

Answer: (D)

Retention duration for poison records is about having information available when it may be needed for safety reviews, recalls, or potential liability inquiries. Five years is the best choice because many regulatory and civil claim windows align with that five-year period, making these records likely to still be relevant if an issue arises. It also accommodates the product life cycle and allows you to trace important details—dates, substances, quantities, lot numbers, suppliers, storage, disposal, and incident reports—through multiple recalls or regulatory checks. Shorter periods can leave gaps for later claims or investigations, while longer periods are often unnecessary and add extra cost. In short, five years strikes a practical balance between usefulness and resource use.
