Taipei, Sept. 23 (CNA) Taiwan has suspended imports from three Vietnamese durian suppliers for one month after shipments were found contaminated with pesticides banned in Taiwan, such as methidathion, dithiocarbamates and carbofuran, the Taiwan Food and Drug Administration (TFDA) said Tuesday. Since July, all Vietnamese durians have been subject to 100-percent border checks, a measure that will remain in place until Oct. 22. To further contain risks, imports from the three suppliers involved will be suspended from Sept. 26 to Oct. 25, Liu said. The three durian shipments were part of the TFDA's latest list of border inspection violations, which included 17 food products, including German collagen drinks and Australian mandarins. As this was the importer's first violation in six months, the sampling rate of its sesame imports will increase to between 20 and 50 percent.
