Central News Agency (Central News Agency Reporter Shen Pei-yao, Taipei, July 3) Regarding the case of carcinogenic substance "benzo[a]pyrene" exceeding the limit in raw materials for salad oil from Chung Lien Oil Co., the Food and Drug Administration (FDA) provided an update today. Experts pointed out that this situation is quite rare for refined salad oil, and one possibility is that it is related to the quality of imported soybeans. However, it is also not ruled out that the manufacturing process control was not sufficiently完善. On July 1, the Ministry of Health and Welfare's Food and Drug Administration received a report from Chung Lien Oil Co., Ltd. that a batch of soybean salad oil raw material, approximately 1,300 metric tons, used by companies such as Fwusow Industry, Formosa Oilseed Processing, and President Enterprise, was found to have carcinogenic substance "benzo[a]pyrene" levels exceeding the regulatory limit. This case affects 18 products and 30 batches. The FDA held a press conference in the evening to explain the recall and disposal of affected oil products, stating that the deadline for removal from shelves was 12:00 PM today. Currently, 6 items have been accounted for, with a total of 17.422 metric tons recovered. Professor Su Nan-wei from the Department of Agricultural Chemistry and Graduate Institute at National Taiwan University stated at the meeting that cases of benzo[a]pyrene exceeding the limit are actually very rare. From the perspective of oil refining, even if the benzo[a]pyrene content in crude oil (raw oil) is high, it should theoretically be reducible after complete refining processes such as degumming, deacidification, decolorization, and deodorization. However, domestic soybeans are almost entirely imported. Su Nan-wei frankly stated that it is difficult for the country to control how the soybeans are dried after harvesting in their country of origin, and whether high temperatures have produced benzo[a]pyrene.
