Customs officers seized 728 bottles of cooking oil bearing suspected false trade descriptions in a series of raids on two wholesalers, three importers and 25 retail shops over the past two weeks. Two men were arrested. In a separate case, tests by the government laboratory of 58 cooking oils showed samples of 'Gourmet's Kitchen' pure corn oil and 'Dor Po Brand' pure peanut oil were not 'pure'. 'Gourmet's Kitchen' was an all soya bean oil and 'Dor Po Brand' was 50 per cent soya bean oil.
