In order to strengthen the hygiene supervision of the oil market, we conducted a sample monitoring of the edible vegetable oil market from March 1996 to March 1999, and the results are reported as follows. 1 source and methods of sample sampling three years, 169 samples from the plant oil, individual oil mill and grain and oil stores.
