This study investigates whether rectal temperature of pigs, prior to slaughter, can give an indication of the risk of
developing pork with PSE characteristics. A total of 1203 pigs were examined, measuring the rectal temperature
just before stunning, of which 794 rectal temperatures were measured immediately after stunning. pH30LT
(M. Longissimus thoracis) and temperature of the ham (Temp30Ham) were collected from about 530 carcasses,
30 min after sticking. The results present a significant positive linear correlation between rectal temperature
just before and after slaughter, and Temp30Ham.Moreover, pH30LT is negatively correlatedwith rectal temperature
and Temp30Ham. Finally, a linear mixed model for pH30LT was established with the rectal temperature of the pigs
just before stunning and the lairage time. This model defines that measuring rectal temperature of pigs just
before slaughter allows discovery of pork with PSE traits, taking into account pre-slaughter conditions.
