Many people are unimpressed by the standards of hygiene in Hong Kong restaurants, a survey by the Democratic Party has found. Of 505 people interviewed last month, 22 per cent said Hong Kong restaurants were 'dirty' or 'very dirty'. Only 15 per cent found them 'clean' or 'very clean' while 57 per cent said standards were average. About 36 per cent of those asked said they had no confidence in the officials of the Food and Environmental Hygiene Department. More than 40 per cent said they considered hygiene the most important factor when choosing a restaurant. About one-third chose by food quality and taste. More than 70 per cent agreed that restaurants should be classified according to their standards of food hygiene and safety. Posting the classifications at eye-catching places was backed by 67 per cent of people. Lawmaker Fred Li Wah-ming, who is also chairman of the Legco food safety and environmental panel, believed the new classification system could help to raise hygiene standards. 'Our survey has found that people are very concerned about the hygiene of restaurants and are demanding an open classification system,' he said. The Government proposed replacing the five-star classification with a scoring system. Inspections will be less frequent but more detailed.
