Deoxynivalenol residues in edible tissue of infested pig

To determine whether deoxynivalenol (DON) infested pig accumulates toxin in edible tissues after 12 h recovery phase, twenty four fatten pigs were randomly assigned to 4 treatments (6 replicate pens per treatment): A (a control diet without detectable DON); B (a diet with 2.09 mg of DON/kg for 4 weeks); C (a diet with 2.09 mg of DON/kg for one meal); and D (a diet with 10.31 mg of DON/kg for one meal). All pigs were feed restrictively with 1.5 kg per meal for a period of 30 d. The liver, kidney, spleen, heart, LM and dorsal fat were collected for determination of DON residue by HPLC-MS. The sample analysis shows that only trace residues of DON were detected in spleen, heart and muscle samples. The residue in liver, spleen and dorsal fat was lower than 6 µg/kg which is far less than the tolerable daily intake (TDI) in humans. Accordingly, the result facilitates accurate prediction of risk that DON is not dangerous for human by consuming DON infested pigs. Key words: Deoxynivalenol, residues, HPLC-MS analysis
