HONG KONG - Hong Kong's Center for Food Safety (CFS), part of the Food and Environmental Hygiene Department (FEHD), released the findings of its food safety report for May.

CFS said that Of the 10,500 food samples tested, 11 were found unsatisfactory and the overall satisfactory rate was 99.9 percent.

A CFS spokesman said about 4,000 food samples were taken for chemical tests. Another 1,600 samples were collected for microbiological tests, while the remaining 5,000 samples were tested for radiation levels. This included roughly 4,700 samples taken from food imported from Japan, according to CFS. The agency sampled vegetables and fruits and their products; meat and poultry and their products; aquatic products; milk, milk products and frozen confections; and cereals, grains and their products.

The microbiological tests examined pathogens and hygienic indicators while the chemical tests were aimed at detecting pesticides, preservatives, metallic contamination, coloring matters, veterinary drug residues and plasticizers.

The CFS completed the testing of 700 samples that included fresh, chilled and frozen pork, beef and poultry, ready-to-eat dishes of meat and poultry served at food establishments, and meat- and poultry-made products, such as Chinese preserved meat, sausages and ham.

CFS said most of the samples of in the meat and poultry category returned satisfactory results regarding pathogens, pesticide residues and preservatives. Three fresh meat samples were found to contain sulphur dioxide, a preservative not permitted in fresh and chilled meat.
