Test results of seasonal food surveillance project on mooncakes (second phase) all satisfactory

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department (FEHD) today (September 25) announced the second-phase results of a seasonal food surveillance project on mooncakes. Some 160 mooncake samples collected were all satisfactory.

A spokesman for the CFS said that the Centre announced the first-phase test results on mooncakes on September 2, with all samples passing the tests. As the Mid-Autumn Festival is around the corner, the Centre conducted the second phase of the surveillance project. In addition to carrying out chemical and microbiological tests, the Centre also conducted nutrition content analysis of mooncake samples. The CFS collected samples of over 20 brands of mooncakes, covering traditional, snowy, ice-cream and other types of mooncakes from various retailers (including online retailers) and food factories for testing.

Chemical tests covered colouring matters such as Sudan dyes, preservatives such as sulphur dioxide and sorbic acid, antioxidants, heavy metals, aflatoxins and mineral oil. Microbiological tests covered pathogens such as Bacillus cereus, Clostridium perfringens, Salmonella and coagulase-positive staphylococci organisms. For nutrition content analysis, the contents of energy, carbohydrates, protein, total fat, saturated fatty acids, trans fatty acids, sodium and sugars of the samples were tested to see if the test results comply with their declared values on the nutrition labels.

Despite the fact that all test results in the two phases of the project were satisfactory, the spokesman reminded people to maintain a balanced diet and avoid excessive eating of mooncakes as they are mostly high in sugar and fat. Some types also contain relatively high levels of salt. Eating too much fat increases the risk of being overweight or obese, while dietary sugar intake is a determinant of body weight and dental caries. In addition, excessive sodium intake will increase the risk of developing hypertension, fatal stroke and coronary heart disease.

He advised people to refer to nutrition labels, particularly on the sugar, salt and fat contents, to make a healthier choice. People should avoid mooncake types with high levels of fat or sugar, i.e. containing more than 20 grams in total of fat or containing more than 15g of sugar per 100g of food. As for reducing salt intake, people can choose low-sodium mooncake types, i.e. containing less than 120 milligrams of sodium per 100g of food.

Members of the public should observe the following "Five Keys to Food Safety" in the purchasing, storage and consumption of mooncakes to prevent food-borne diseases:

* Buy mooncakes from reliable outlets rather than patronising unlicensed hawkers; check whether the mooncakes are properly packaged, pay attention to the expiry dates before purchase and eat them within the recommended period;

* Store mooncakes in a refrigerator immediately after purchase (snowy mooncakes should be kept at 4 degrees Celsius or below, and ice-cream mooncakes at minus 18 degrees C or below) and consume them as soon as possible after taking them out from the refrigerator;

* Use an icebox to carry snowy or ice-cream mooncakes outdoors and consume them as soon as possible;

* Wrap mooncakes properly and separate them from raw food while storing to prevent cross-contamination; and

* Maintain good personal hygiene. Wash hands properly with liquid soap and running water before handling mooncakes.

The spokesman also reminded food traders to adhere to the Good Manufacturing Practice. Other than purchasing food ingredients from reliable suppliers, they should also comply with legal requirements when using food additives.

"Snowy and ice-cream mooncakes, which do not undergo a baking process at high temperature, need to be handled hygienically during processing, transportation and storage to avoid contamination and growth of germs," he said.
