Multiple batches of camellia oil in Taiwan have tested positive for exceeding the legal limit of benzopyrene, a carcinogenic substance. The Taipei City Government is investigating the source of the contamination, revealing that the problematic oil originated from the same manufacturing facility as products made by Yong Feng Yu (Evergreen Paper). This discovery follows previous instances of camellia oil failing safety tests, raising concerns about widespread issues in the production chain. Authorities have initiated recalls of the affected products and are reviewing safety protocols at the factory. Initial investigations suggest the contamination may stem from processing techniques, and further analysis is underway to pinpoint the exact cause. The incident highlights the need for stricter quality control measures in the food processing industry in Taiwan. Consumers are advised to exercise caution when purchasing camellia oil and to check product labels for recall information.
