Taiwan's Cooking Oil Recall: What Happened and What It Means for Eating Here

If you've seen news about a cooking oil recall in Taiwan and wondered whether it affects what's on your plate, here's the situation.

What happened

Soybean cooking oil produced by 中聯油脂Zhōng lián yóu zhī (Central Union Oil Corp), a Taichung supplier, tested at 8.1 parts per billion of benzo[a]pyrene (BaP) — roughly four times Taiwan's legal limit of 2 ppb. BaP is classified as a Group 1 carcinogen by the International Agency for Research on Cancer; it can form during high-temperature processing.

The timeline is what turned a contamination case into a scandal. A downstream customer detected the problem in May. Health officials say Central Union was informed on June 11 but didn't notify authorities until June 30. For sitting on it, the company was fined NT$165.2 million — reported as the largest fine ever imposed on a single company under Taiwan's food safety act. Prosecutors raided the company on July 10, and its general manager was released on NT$20 million bail the next day while the investigation continues.

How big is it

About 1,300 tonnes of the affected oil were distributed between April and June to three major food companies — 泰山Tài shān (Taisun), 福壽Fú shòu (Fwusow), and 福懋Fú mào (Formosa Oilseed) — and from there into hundreds of downstream products. Because the company's own retained samples produced conflicting test results, regulators stopped trusting them and expanded the recall as a precaution to cover all Central Union oil from that period, plus foods made with it.

As of July 8, the recall list stood at over 400 products, and it has kept growing. It includes names you'll actually recognize: 33 products from Louisa Coffee, items from bakery chain Le Blé d'Or, 老協珍Lǎo xié zhēn (Lao Xie Zhen) rice burgers, packaged chicken products, instant noodles, and convenience-store ready meals. Restaurant group Wowprime reportedly confirmed that a hot pot broth base at its 青花驕Qīng huā jiāo brand and a retail shacha sauce had used affected batches at some southern locations.

What it means for you

The affected products are being pulled, and anything recalled as a precaution can only return to shelves after passing inspection — the Premier has ordered batch-by-batch checks. The recall is mostly about packaged goods and ingredients working their way through supply chains, not about any particular restaurant's cooking. Authorities have framed the expanded recall explicitly as precautionary, with testing of remaining batches ordered to finish within a week.

If you want to check a specific product, the TFDA publishes the recall list (Chinese-language); convenience stores and supermarkets have been clearing flagged items, and affected chains are offering refunds.

Worth knowing for context: Taiwan takes cooking oil scandals seriously because it has been here before — the 2014 gutter oil scandal reshaped the country's food safety enforcement, and this case is already prompting talk of amending the food safety act again. The system that caught this was imperfect and slow, but it did catch it, publish it, and fine the company a record amount in a matter of days once regulators knew.

We've talked about Louisa Coffee — their recalled items are packaged products from the affected supply chain, part of the precautionary sweep. We'll keep this post updated as the list changes.

Update — July 29, 2026

The investigation has reported back. On July 27 the FDA released the findings of an independent expert panel, convened by the Food Industry Research and Development Institute, into how the contamination happened. The short version: it was a management failure, not a broken machine. Investigators found no direct evidence that Central Union's process or equipment generated the benzo[a]pyrene. What they found instead was that oil made from Brazilian-imported soybeans tested higher for BaP than oil made from US beans, with levels varying between shipments — and that the company didn't respond to that. No tighter oversight of those raw materials, no increase in testing frequency, no additional production controls. It had also relaxed quality-control standards for higher-risk inputs without increasing testing of either ingredients or finished products, and BaP wasn't included in its food safety management system at all. Minister Without Portfolio Chen Shih-chung, presenting the results, described the cause as a combination of management failures rather than any single point of failure.

The batch testing is finished. Of the 30 batches Central Union produced between April and June, seven failed to meet safety standards, 22 complied (including three that were never shipped downstream), and one had been exported with no retained sample to test. That closes the precautionary sweep described above: the net was cast over all 30 batches while testing ran, and most came back clean. Seven is up from the five confirmed when this post first went up.

The law is moving. The Executive Yuan approved draft amendments to the Act Governing Food Safety and Sanitation on July 23 and sent them to the Legislature. The proposals target source management, production process controls, abnormality reporting, quality management, reporting of test results, and digital governance — much of it aimed at the reporting delay that turned a contamination case into a scandal. The criminal investigation runs separately and is ongoing, with further searches conducted and executives at downstream companies detained since this post was published.
