Taiwan’s health authorities have ordered a precautionary recall of processed foods containing at least 20% of soybean salad oil produced by Taichung-based Central Union Oil Corp. after tests found excessive levels of the carcinogen benzopyrene. Health Minister Shih Chungliang said the 20% threshold follows food safety recall guidelines established in 2017 and reaffirmed at an expert meeting on Saturday, according to the Central News Agency (CNA). The TFDA said affected products must be pulled from shelves by midnight July 6, while products with smaller amounts are exempt from recall but must be disclosed.
