Can you detect fecal matter with a blacklight?

Yes, fecal matter can often be detected with a blacklight because it contains certain compounds that fluoresce under ultraviolet (UV) light. Specifically, proteins and certain bacteria in feces may emit a glow when exposed to blacklight. However, the effectiveness of detection can vary depending on the specific composition of the feces and the conditions of the environment. It's important to note that while blacklights can aid in identifying contamination, they are not a definitive method for detecting fecal matter.
