Tests find oil legal, but not fit for food: FDA

FDA LAB TESTS:A sample from unrefined oil exceeded legal standards for acid value of edible lard, but a sample taken from a finished product was within the guidelines

By Stacy Hsu  /  Staff reporter

Chang Guann has been at the center of a snowballing oil scandal that erupted after 782 tonnes of its edible “fragrant lard oil” products were found to contain about 247 tonnes of recycled waste oil, which should have been disposed of or used in the production of soap.

As of yesterday, the FDA had identified 1,248 companies that bought the tainted edible oil or products made with them, up from 1,207 on Sunday, while it said the number of types of products contaminated with the waste oil rose from 136 on Sunday to 208.

Asked to comment on the FDA’s test results, Linkou Chang Gung Memorial Hospital toxicologist Yen Tsung-hai (顏宗海) said that they left him with several concerns.

“First, the FDA did not collect enough samples for testing, nor did it take a sample of the waste oil sold by Kuo to Chang Guann. Chances are the test results only look nice because the samples the FDA tested on had been drawn from batches of oil that were less contaminated,” Yen said.

Second, since the agency conducted standard tests, Chang Guann’s problematic lard could contain other toxic substances that are not normally tested by the FDA, Yen said.

“If a student already knows what questions are going to be on a test, it will be harder to fail than to pass it,” Yen added.
