By Kim Rahn Staff Reporter Coffee and unsanitary donut? Internet users have paid attention to a writing allegedly exposing a doughnut company's unsanitary production process and the firm's refutation against the claim. The writing, titled ``Truth About Dunkin Donuts,'' was posted on a portal site "Daum," by a person who said he has worked for the company's subcontractor at a factory in Guro, western Seoul, for five years. The writer claimed workers at the factory make doughnuts without washing their hands, or sometimes make doughnuts with dough that has fallen on the floor. ``We sometimes made doughnuts with ingredients that had passed the expiration date. We produced doughnuts with rust stains from old boilers for three months. Many machines and trays were rusty and we did not wash them thoroughly,'' he claimed. He also said the company changed the rusty boiler after a customer complained about rust on the doughnuts, but that workers were ordered to lie about the equipment. As evidence, he posted pictures of the boiler. ``More than 70 percent of the ingredients used in making doughnuts are imported. Some of these ingredients were exposed to chemicals and the company stopped producing an item made with the ingredients last October before the Korea Food and Drug Administration's crackdown,'' the writer said. He claimed the company makes doughnuts with genetically modified products, but without informing customers. He added that they made doughnuts with ingredients different from what the company reported to the health authority. The writer also said that the company has not properly paid workers or provided treatment and compensation to workers who were injured on the job. Regarding the writing, Dunkin' Donuts posted an article on its Web site, saying the writer's claim was false, and has had the writing removed from Daum and other Internet sites through legal procedures. The company said it has undergone inspections from related authorities about the issue the writer suggested, such as ingredients and facility sanitation, and attached the inspection record issued by the food administration to the Web site. ``Dunkin' Donuts gives sanitation education to workers regularly, and cleans trays and facilities every day. The boiler on the pictures was not one used at the factory,'' it said. Internet users remain dubious about the situation, as the two sides offer vastly different opinions. ``Dunkin' Donuts should inspect the sanitation standards of its subcontractors and inform the public of the result. It is the their obligation,'' an Internet user with the ID ``meongmeongi'' said. rahnita@koreatimes.co.kr
