Describe proper evidence packaging for microorganisms or biohazards.

• A. Use leak-tight primary and secondary containers, proper labeling, biohazard precautions, double-bagging when needed, seal, and maintain chain-of-custody
• B. Pack in loose bags and expose to air
• C. Store in normal mailers
• D. Seal in plastic wrap without transparency

Answer: (A)

The main idea here is containment, safety, and traceability when handling evidence that contains microorganisms or biohazards. Proper packaging must prevent any leakage or exposure, protect the sample’s integrity, and keep a clear, unbroken record of who handled it. Using leak-tight containers on both the primary container and any secondary container, with correct labeling and clear biosafety precautions, is essential. Double-bagging when needed adds an extra layer of protection in case the inner container fails. The item should be sealed and accompanied by documentation that maintains chain-of-custody, so every transfer of the evidence is recorded and verifiable. This is better than the other options because loose bags expose contents to air and potential leakage; normal mailers are not designed for hazardous materials and lack proper containment and labeling; plastic wrap without transparency fails to provide containment, visibility, or tamper-evidence. All of these aspects—containment, labeling, precautions, sealing, and chain-of-custody—work together to keep people safe and preserve the evidentiary value.
