MAJOR flour manufacturers are considering taking legal action against the Director of Health, Dr Lee Shiu-hung, if he refuses to correct alleged inaccuracies made in a statement about a cancer-causing additive found in local flour. Hong Kong Flour Mills and Kowloon Flour Mills, two of the territory's biggest producers, will meet Dr Lee this afternoon to discuss the use of potassium bromate. The director and general manager of Hong Kong Flour Mills, Thomas Poon Pik-kin, said: ''Our lawyers have instructed us not to discuss the nature of the inaccuracies and whether or not we use the additive. ''But what has been said is detrimental to our interests and an inconvenience to the public and so we will be asking Dr Lee to publicly clarify a number of points.'' On Sunday, the Department of Health ordered flour manufacturers to stop using potassium bromate after international research found that it might cause cancer. Dr Lee said the department had sent warning letters to flour manufacturers after routine tests found low traces of potassium bromate. But Mr Poon said: ''I can assure the public that every aspect of our flour production relating to health is of the highest standard.''
