Cross-Contamination, as it applies in forensic evidence, can be defined as the transfer of
evident materials from two or more sources. Contamination may occur after, before, or during
the collection of evidence by the authorities from the scene hence interfering with the
investigations. For example, when collecting blood samples in a scene and combines with other
samples hence contaminating them. There are measures used in the prevention of cross-
contamination, such as wearing protective gear, the use of disposable instruments in sample
collection, and proper handling of samples. It is important to understand ways of preventing
cross-contamination from ensuring effectiveness during sample collection.

measures and results obtained.
