The work was carried out to evaluate the physical and sensory characteristics of PSE pork, their correlations and damages caused to the industry because of its occurrence. In a commercial slaughterhouse has measured the pH of carcasses (n = 1601) at 45 minutes post mortem (pH45), classified them into PSE (pH45 < 5.8) or normal (pH45≥ 5.8). After 24 hours of cooling were collected the samples from the Longissimus dorsi muscle of the 26 normal and 26 PSE carcasses that were evaluated for color (L*, a*, b*), exudate loss, cooking loss, shear force, sensory attributes (tenderness, juiciness and flavor) and centesimal composition. Were evaluated the correlations between the physical and sensory parameters. The final pH, cooking loss, shear force and centesimal composition did not differ between the types of meat. The exudate loss was 39% higher for the PSE meat. The pH45 was negatively correlated with L* (R= -0.331) and b* (R = -0.528). The juiciness was positively correlated with flavor (r = 0.436) and tenderness (R = 0.297) and negatively with cooking loss (R = -0.326). The shear force was positively correlated with exudate loss (R = 0.529) and negatively with tenderness (R = -0.767). The estimated loss due to the occurrence of PSE meat were of R$340,800.00 per year. The PSE meat show negative changes in the functional and sensory properties, almost all related to reducing its water holding capacity, causing considerable losses to the processing industry.
