The 10 products were found to contain between 0.1 ppm and 1.8 ppm of glyphosate, a widely applied pesticide in the United States and other parts of the world, according to the FDA.
Taiwan currently does not allow glyphosate in oatmeal products.
The products found to contain glyphosate included Coach's Oats cracked and toasted oats and Quaker quick 1-minute oats imported by RT-Mart; Quaker old-fashioned oats and Quaker quick 1-minute oats imported by Carrefour Taiwan; and Quaker old-fashioned oats imported by Costco Taiwan.
Also on the list were Fifty50 low glycemic hearty cut oatmeal and McCann's Irish oatmeal imported by the Far Eastern Retail Group; Bob's Red Mill instant rolled oats imported by Macroscopic Co.; Australia fine oat flakes imported by Fu Yuan Foods Co.; and an unbranded oatmeal product imported by Fong Gwo food company.
According to Wang Teh-yuan, deputy director of the FDA's Northern Center, glyphosate is a relatively safe agricultural pesticide that is usually expelled from the human body in urine and stool.
At present, the maximum level of glyhosate residues allowed in foods is 30 ppm in the United States, 20 ppm in Japan and the European Union, 15 ppm in Canada and 0.1 ppm in Australia, Wang said.
Because Taiwan has a ban on glyphosate residues in oatmeal products, the importers are required to recall the 10 affected products or risk a fine of up to NT$200 million (US$6.16 million), he said.
Also on Thursday, Standard Foods Corp., which is licensed by U.S.-based Quaker Oats Company to produce, distribute and market Quaker products in Taiwan, said the U.S.-originated Quaker products found to contain glyphosate were unrelated to those produced by the company in Taiwan.
Standard Foods said all its Quaker oatmeal products are manufactured in Taiwan using mainly ingredients from Australia that have passed pesticide tests. (By Chang Ming-hsuan, Han Ting-ting and Y.F. Low)
