red heat
A defect in hides and skins, appearing as red or
colored patches on the flesh side of the skin, and
caused by the action of halophilic bacteria, which
are bacteria acclimated to living in salt
solutions. The presence of "red heat" suggests
putrefaction and consequent damage to the skin.
The presence of halophilic bacteria in the cured
skin may result from the use of marine salt, or
the reuse of salt previously used in wet salting.
