(I)(i) Food Safety Day — Food Temperature Control cum Signing of Food Safety Charter

Hi, everybody! As a young reporter, I always like trying various delicacies, and take great stock in food safety. To promote the importance of the tripartite collaboration among the Government, the food trade and the public in enhancing food safety, the Food and Environmental Hygiene Department (FEHD) and Radio Television Hong Kong (RTHK) jointly organized the Food Safety Day — "Food Temperature Control" cum "Signing of Food Safety Charter" on July 24 this year at Plaza Hollywood, Diamond Hill. I will now give a detailed report on this publicity drive.

Officiating at the "Food Safety Day" opening ceremony were Dr York CHOW Yat-ngok (centre, front row), the Secretary for Health, Welfare and Food, Dr MAK Sin-ping (right, front row), the acting Director of Food and Environmental Hygiene, and Mr Eric NG Ka-lim (left, front row), the Head of Radio 5 of RTHK.

The "Food Safety Day" is part of the Government's publicity drive to promote food safety awareness among the food trade and members of the public. Featuring performances by star singers, game booths with attractive souvenirs, short educational film shows and exhibition on food safety, the event aims to:

Officiating at the brief yet solemn opening ceremony were Dr CHOW Yat-ngok, the Secretary for Health, Welfare and Food, Dr MAK Sin-ping, acting Director of Food and Environmental Hygiene, Mr Eric NG Ka-lim, the Head of Radio 5 of RTHK, as well as Legislative Councillors and representatives of the Consumer Council and the trade. The ceremony symbolizes the tripartite cooperation among the Government, the food trade and the public in promoting food safety.

By signing the "Food Safety Charter," major stakeholders show all sectors of the society their commitment to strictly uphold the principles and responsibilities set out in the charter in the course of food preparation.

At this year's event, we are glad to have the full support of Mr Martin YAN Man-tat, the world-renowned chef, who was the Food Safety Ambassador and played a leading role in the two short educational films "美味食物Wonderful" and "美味食物You Can Cook." His international fame will surely help drive home the food safety messages.

As regards the performances, all star singers did their very best to perform hit songs. They also joined the audiences in a quiz game. While listening to the intoxicating songs and making close contact with their idols, the audiences would acquire a deeper understanding of food temperature control and the "temperature danger zone." This year, a theme song called "食物安全要注意" was meticulously written for the "Food Safety Day." Through the performances of the star singers, food safety messages wrapped in enchanting melodies were carried to every corner of the Plaza.

In another corner of the venue, display boards with food safety tips were provided for members of the public, who could also pick up well-designed leaflets containing a wealth of information on food safety.

At this year's "Food Safety Day" , there were a number of game booths awarded attractive souvenirs, including "Refrigerator Game - Ball Pond" and the "tooth-hitting" game called "Down with Food Poisoning Germs." Besides, FEHD had also produced two brand-new computer games called "Bug Buster" and "Young Chef at High Temperature." Participants could play the games with their family members to obtain more knowledge on food temperature control. This was surely "learning through playing, and playing through learning." The participants would receive fabulous souvenirs including magnetic labels with the message of "Control Food Temperature Properly 4 to 60 Degrees is Risky" imprinted, miniature handkerchiefs, ball pens, fluorescent pens, notebooks, and environmentally-friendly shopping bags in many different colours. The game booths, which opened from 10:00 am to 5:30 pm, attracted an endless stream of people. It was estimated that the event drew as many as 24 200 participants.

(II) Food Consumption Survey

The Food and Environmental Hygiene Department (FEHD) is conducting Hong Kong's biggest and most comprehensive food consumption survey to collect information on food consumption patterns of the general public and evaluate the risks associated with food. In the past, only small scale studies for collecting food consumption data were conducted in Hong Kong. As no territory-wide food consumption data was available, it is crucial for FEHD to conduct this food consumption survey to establish a comprehensive database for food safety risk assessment. The survey will also enhance the department's risk assessment capacity. Moreover, such information will be useful for the Government to formulate public policies and education strategies to promote food safety in Hong Kong.

The food consumption survey will collect food consumption data of the local population, such as (1) types of food intake, (2) amounts of food intake and (3) dietary habit. FEHD has commissioned the Chinese University of Hong Kong (CUHK) to conduct this survey. The CUHK survey team consists of experts in nutrition, public health and statistics as well as well-trained interviewers.

From March 2005 to March 2006, selected households will receive an invitation letter from FEHD explaining the interview arrangement. Selected household will be invited to contact the CUHK Survey Unit by telephone so that one participant can be recruited from each household. For further information, please call the FEHD Hotline 2868 0000, or call the CUHK Survey Unit at 2609 6876 during office hours, or e-mail to the CUHK Survey Unit at hkfcs@cuhk.edu.hk.

Invited households are appealed to render their full support and cooperation by accepting the interview when called upon and providing accurate information.

Food Safety Tips

(I) Safety Tips for Consuming Fresh Water Hairy Crabs

When refreshing wind blows, we know that autumn has arrived. Autumn is the season for outings and seasonal delicacies, such as hairy crabs. When eating hairy crabs, consumers should pay particular attention to food safety and to maintain a balanced diet, consumers should also avoid eating too many hairy crabs, particularly the cholesterol-rich roe and sperm. Patients with chronic illnesses should limit their intake of hairy crabs.

Crab-lovers are advised to heed the following safety advice:

In the shop

  • Buy hairy crabs from reputable shops and restaurants.
  • Hairy crabs for sale must be kept in the refrigerator.
  • Buy live hairy crabs with intact, shiny shells without a foul smell.



  • Wash hands with soap and water before eating hairy crabs.
  • Completely remove the offal of hairy crabs before eating.
  • Avoid eating raw crabs. Do not believe that condiments such as salt, vinegar, wine and wasabi can kill bacteria.
  • Maintain a balanced diet and avoid eating too many hairy crabs, particularly the cholesterol-rich roe and sperm.
  • Children, pregnant women and patients with chronic illnesses should only eat hairy crabs in moderation.

(II) How much do you know about Noroviruses?

Noroviruses have been identified as one of the major causes of non-bacterial gastroenteritis in many countries. Although it can cause food poisoning, this foodborne hazard can easily be prevented. Let us learn more about the viruses.

Q: What are Noroviruses?  
A: Noroviruses are also known as Small Round Structure Viruses (SRSVs). Gastroenteritis caused by Noroviruses is usually mild and self-limiting. Symptoms include nausea, vomiting, non-bloody diarrhea and abdominal cramps. According to the literature, Noroviruses are common pathogens of viral gastroenteritis. As the disease caused by Noroviruses is more common in winter, it is also known as "Winter Vomiting Syndrome" .
Q: How do the Noroviruses spread?  
A: Infected human is the only known host for Noroviruses. Fecal contaminated food and water are the main media of transmission. Other modes of transmission include person-to-person spread, direct contact with contaminated objects and aerosol spread.
Q: What kinds of food are prone to be contaminated by the viruses?
A: Noroviruses can be found in sewage. Shellfish harvested from polluted water zone or nearby waters and vegetables irrigated with polluted water are more likely to be contaminated by the viruses. Ingestion of raw or inadequately cooked foods (including shellfish, salad and vegetables), is prone to a higher risk of Noroviruses infection. In Hong Kong, ingestion of raw oysters is one major reason of Noroviruses infection.
Q: How to prevent Noroviruses infection?
A: The key to prevention of Norovirus infection is strict observance of food, personal and environmental hygiene.

Interpretation of Ordinance

How to control food unfit for consumption?

In Hong Kong, there is a complete set of food ordinance to control and ensure food safety. Section 54 of the Public Health and Municipal Services Ordinance (Cap. 132) requires that all foods for the purpose of sale in Hong Kong shall be fit for human consumption.

Section 59 of the Ordinance authorizes an FEHD officer to seize, remove and destroy any food which is unfit for human consumption to protect public health. FEHD's Health Inspectors will regularly examine foods which are intended for human consumption at import, wholesale and retail levels in addition to examining foods on food premises. If a Health Inspector suspects that the food is unfit for consumption, he may seize and remove such food or affix to such food a mark or seal, or even destroy the food.

Any person who sells food which is unfit for human consumption or any food on which a mark or seal is affixed commits an offence and shall be liable to a fine of $50,000 and to imprisonment for 6 months.
