Residue of ochratoxin A in swine tissues: Risk assessment

Results: Of the 60 plasma samples, 60% contained ochratoxin A in the range of 2.5-33.3 ng/mL (mean 3.05±5.0 ng/mL), while the incidence of ochratoxin A in kidneys and liver were very similar (70% and 65%). The average ochratoxin A concentra- tion in liver was 3.2±4.35 ng/g (1.2-19.5 ng/g) and in kidneys was 3.97±4.47 ng/g (1.3-22.0 ng/g). A statistically significant difference (p liver>serum (100>80.8>77%). The results from this survey indicated that there was a strong correla- tion between the ochratoxin A level in serum and liver as well as in the ochratoxin A serum in kidney (r=0.884 and r=0.896, respectively) while the strongest correlation was found between the ochratoxin A level in liver and in kidney (r=0.970).
