Re: If a human body is frozen then thawed, how long before it begins to smell?

I can't give you a definative answer for this question as it is well outside my areas of expertise.

I can help a little though! Amongst other things, I'm a farmer. I can certainly give you some ideas. An animal starts to smell within a few hours of death.

The crucial variables include: temperature, exposure, ventilation, humidity, insect predation, covering, and more.

The body would smell almost immediately. A dead body often releases fluids. It would depend on how the body was prepared before freezing.

It is possible that two days is not sufficient to completely freeze the body.

The outer surface areas would defrost [depending on ambient temperature] in a short time allowing decomposition to start immediately on those parts.

I think the real option for you is to purchase a freshly killed pig. Go through the procedure and experience for yourself what happens.

Let me know when you publish. I might be your first reader!
