What must you do with biological evidence to prevent degradation?

To prevent degradation of biological evidence, it is essential to package and store it properly. Proper packaging is crucial because it protects the evidence from environmental factors that can lead to contamination or deterioration. Biological materials, such as blood, saliva, or tissue, can be particularly vulnerable to temperature changes, humidity, and exposure to light, which may promote bacterial growth or affect the integrity of the sample.

Secure packaging methods, such as using breathable containers for dry samples or refrigerated methods for wet samples, help to maintain the quality and viability of the evidence, which is vital for any subsequent forensic analysis. Proper storage conditions, such as temperature control, further contribute to preventing degradation over time.

Inappropriate handling methods, such as immediate disposal or leaving evidence at the crime scene, would compromise its integrity and usefulness for investigations or legal proceedings. While storing biological evidence in a freezer can help preserve it, the key factor in successfully safeguarding the evidence lies in proper packaging and storage practices.
