Patulin in apple juice and its risk assessments on albino mice

The contamination of apple juice with patulin mycotoxin is a major risk factor in food safety. This study focuses to assess the biochemical and histopathological effects of patulin in apple juice samples collected from different outlets retailing in Jeddah, Kingdom of Saudi Arabia. On the basis of the selected dose level, 152.5 ppb patulin/ml was administered daily orally for up to 6 weeks to male albino mice. The exposure to contaminated samples revealed significant elevation of all the studied blood parameters (alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activities as well as creatinine, urea and uric acid contents). On the other hand, and with regard to the accumulated neuronal toxicity of the tested dose level, the toxic signs were recorded as significant increase in the aggressive and locomotor behavioral changes. In addition, the brain areas monoamines concentration revealed variable increased changes. The potential maximal changes in norepinephrine, dopamine and serotonin5-hydroxytryptamine levels attained in cortex, hypothalamus, striatum, hippocampus, midbrain and pons and medulla were assessed. Moreover, the histological examination revealed degeneration and necrosis in liver tissues and degenerated glomeruli and hemorrhage between the tubules of the cortical region in kidney tissues. The study declared that patulin-contaminated (152.5 ppb) apple juice exhibited liver, kidney and neurotoxicological effects in 6 weeks orally administered mice.
