Methods: Arsenic content in the bulk food wrapping paper was determined by silver diethyl-dithiocarbamate method. Results: There were 16 kinds of bulk food wrapping paper in survey, arsenic was found in 12 samples and the detection rate was 75%, all 12 samples met the national standard of arsenic content, the pass rate was 100%. Detection rates were significantly different in samples from the major supermarkets to the bulk-stores, however, there was no difference of the arsenic content among samples from supermarkets and the bulk-stores. The contents of printing ink were also different in samples from the major supermarkets to the bulk-stores, but with the same pass rate. Conclusion: The sanitation status of bulk food wrapping paper in Dali is good but with relatively high content of arsenic, to which the health supervision departments should pay attention.
