Fan Zhen, a senior official at Jiugui Liquor, has raised doubts over the methods used by the company which conducted the test and said he is also uncertain whether the liquor that was tested was produced by Jiugui, according to a report from stcn.com, a news portal under the Securities Times.
The company has already sent some samples of its products to authorized test agencies, said the report.
The report on 21cbh.com said that the test was conducted by third-party quality tester Intertek.
Henry Lin, a spokesperson for the Shanghai office of Intertek, told the Global Times Tuesday that he is not authorized to reveal clients' information, but admitted they had tested some liquor samples.
"The entire testing process of Intertek is in accordance with Chinese standards," said Lin.
Liu Hui, a senior analyst at Capital Securities, told the Global Times that the industry is recovering from the incident, and the situation is far less serious than the melamine scandal in the dairy industry in 2008.
