The [[Liver - Anatomy & Physiology|liver]] undergoes autolysis rapidly and can be advanced before it is obvious in other tissues.
 +
Post mortem changes must not be mistaken for pathological changes.  The following are changes expected with post-mortem changes.
 +
 +
===Gross===
 +
*pallor
 +
**pale areas appear on the capsular surface as bacterial degradation begins
 +
*friability
 +
*greenish blue colour
 +
**the colour is because bacteria degrades blood pigment to hydrogen sulfide
 +
**particularly the liver adjacent to the intestines
 +
*brownish colour
 +
**the [[Liver - Anatomy & Physiology|liver]] adjacent to the [[Gall Bladder - Anatomy & Physiology|gall bladder]]
 +
**bile pigment from the wall of the [[Gall Bladder - Anatomy & Physiology|gall bladder]] passes through to the [[Liver - Anatomy & Physiology|liver]]
 +
*bubbles of gas
 +
**produced by post-mortem bacterial growth
 +
*puttylike consistency
 +
===Microscopically===
 +
*no cellular reaction
 +
*large number of gram positive bacilli present
 +
 +
NB: The proliferation of bacteria will be even greater in large animals during hot weather, especially cattle, in which fermentation in the adjacent [[The Rumen|rumen]] produces heat

::In addition, pigs, as they are often well insulated by fat
