DNA fluid such as blood or sexual assault fluids should always be kept in a plastic evidence bag.

Explanation:
Biological evidence needs to be preserved in a way that protects DNA from degradation and contamination. Fluids like blood or sexual-assault fluids should be dried first and then packaged in a breathable container, such as a paper bag or envelope. Plastic bags trap moisture, can promote mold and bacterial growth, and may hinder drying, all of which can damage DNA and complicate analysis. For that reason, saying they should always be kept in a plastic evidence bag isn’t correct. The standard practice is to air-dry the material and use breathable packaging, with plastic only used in specific, controlled circumstances.
