Food safety is once again in the limelight following media reports that a "significant portion" of used cooking oil from Taiwan was being recycled and returned to people's dining tables.
Taiwan has ordered the cooking oil supplier at the centre of the food scandal to pull all of its "Chuan Tung" lard oil products from store shelves, even product that passes food safety tests.
Taiwan's Food and Drug Administration released test results showing that one sample of the oil sold under the Chuan Tung brand met requirements.
But samples from two other batches - obtained by prosecutors investigating the scandal - failed.
The FDA also says there is no record of Chang Guann importing gutter oil from the mainland.
