ELISA results of HEV-IgG performed in serum samples collected from 156 slaughtered pigs (grey points). Samples absorbance was expressed as the percentage of absorbance(pOD) in comparison with the absorbance of the positive control of the plate. Samples with a pOD higher than 70% are considered positive, while samples with a pOD lower than 60% are detected as negative. The bold black lines delimit the doubtful range of the test
