The examination result of arsenic, solvent residues, aflatoxins can meet the standard. The content of acid value and peroxide value was over the standard in 5 and 2 samples respectively. There was a difference of the qualified rate of edible vegetable oil in different units （ P 〈0.01） ,the passing rate of different types of vegetable oils have statistically significant differences （ P 〈0. 01）. [Conclusion] Acid value and peroxide can affect the hygienic quality of edible vegetable oil sanitation, supervision and inspection on the hygienic status of edible vegetable oil should be strengthened.
