For how long must a poison registry be maintained?

The requirement to maintain a poison registry for a period of two years from the last entry aligns with regulations intended to ensure both public safety and effective monitoring of potential poison exposure incidents. This two-year retention period allows relevant authorities to access necessary information for evaluating trends in poisoning cases and contributes to public health research and response strategies.

Maintaining records for this length of time also provides a reasonable timeframe for public health officials and poison control centers to review cases for epidemiological studies and to trace patterns that might indicate outbreaks or safety concerns related to specific substances. By providing access to this information for two years, it balances the need for record-keeping with the practical considerations of the healthcare environment, such as storage limitations and the relevance of older data.

Other durations, such as one year, three years, or five years, may not adequately cover the time frame needed for investigating poisoning cases or may place undue burdens on facilities regarding data management.
