At what approximate time does putrefaction typically begin?

Putrefaction typically begins around 18 hours after death. This process is characterized by the breakdown of body tissues due to the action of bacteria and other microorganisms, leading to the production of various gases and odors.

In the hours following death, the body's systems start to shut down, and the environment within the body becomes conducive for bacterial growth. By approximately 18 hours post-mortem, the processes leading to putrefaction are well underway, making it a crucial timeframe to understand in forensic investigations.

While the process may initiate earlier, it is around this time that the signs become significantly pronounced and noticeable. Investigators in forensic medicine often rely on this timing to assess the time of death in cases of unexplained fatalities. Understanding the timing of putrefaction is essential for accurately estimating the post-mortem interval.
