The benzo[a]pyrene contamination that began with Zhonglian Oil’s soybean salad oil in early 2026 has expanded to multiple oil categories and drawn intense political and legal attention. By early July, a 1,300‑ton batch exceeded legal limits, prompting the TFDA to identify 360 downstream firms, order recalls of over 440 items, suspend Zhonglian’s production and impose a NT$1.652 billion fine. Senior executives were detained for evidence tampering, and the Legislative Yuan held a special hearing demanding transparency.

In August, TFDA detected benzo[a]pyrene above the 2 µg/kg limit in bitter‑tea oil from five manufacturers, ordering recalls and expanding inspections of imported seeds. A criminal investigation led to arrests of WeiJia Co. managers and staff, with bail set at NT$1 million and NT$500,000 respectively. Eight batches of bitter‑tea oil were non‑compliant, affecting brands such as Lian‑Jing and De‑Chang. The source of contamination remains under investigation.

Separately, state‑owned Taiwan Sugar Corp. found a Zhonglian‑supplied crude oil batch (311号油槽) with far‑excessive benzopyrene but did not report it, claiming the material was a raw ingredient. KMT legislators demanded a full probe and disclosure of the contaminated volume, while the Ministry of Economic Affairs argued reporting obligations apply only to finished foods, sparking debate over oversight.

KMT legislator Chen Yi‑hsin again criticized Food Safety Office director Hsu Fu over the 20 % oil‑removal threshold. Health Minister Shih Tsung‑liang testified that the figure reflects expert consensus and that de‑gummed crude oil is a semi‑finished product not subject to mandatory reporting. He noted that after a June 30 alert, Zhonglian was ordered to halt production and inspections found seven non‑compliant batches out of 224 tested. The government continues to offer compensation through a consumer‑protection fund and pledges a full investigation to protect school meals and military rations.
