The Centre for Health Protection (CHP) of the Department of Health (DH) today (February 7) reminded the public, particularly the elderly and people with chronic illnesses, to adopt appropriate measures to protect their health in view of the cold weather.

     A spokesman for the CHP said that cold weather can easily trigger or exacerbate diseases, especially among the elderly and persons suffering from heart disease, respiratory illness or other chronic illnesses.

     "Elderly people have less insulating fat beneath their skin to keep them warm and their body temperature control mechanism may be weaker. Their body may not be able to appropriately respond to the cold weather," the spokesman said.

     Some senior persons may have decreased mobility, which can in turn impair their ability to generate and conserve body heat. Chronic illnesses, such as hypertension, diabetes and endocrine disorders may undermine the health of elderly people and lower their metabolic rate, subsequently causing their body to generate less heat. Persons with chronic illnesses such as chronic respiratory illnesses or heart disease are vulnerable to disease aggravation due to cold weather.

     The CHP reminded the public, in particular the elderly and persons with chronic illnesses, to adopt the following preventive measures:
 

• Take note of the weather forecast. Wear warm clothing, including hats, scarves, gloves and socks accordingly;
• Consume sufficient food to ensure adequate calorie intake;
• Perform regular exercise to facilitate blood circulation and heat production;
• Stay in a warm environment and avoid prolonged outdoor exposure;
• Use heaters with care, and maintain adequate indoor ventilation; and
• Seek medical advice if feeling unwell.

     In addition, the public should avoid alcoholic beverages.

     "Drinking alcohol cannot keep you warm. Alcohol accelerates the loss of body heat through dilated blood vessels, resulting in chilling instead," the spokesman said.

     "Parents should ensure that babies are sufficiently warm, but it is also important to keep babies relatively lightly clothed to avoid overheating them," the spokesman added.

     Parents should observe the following safety measures when putting their children to bed:  

• Keep the room well ventilated and at a comfortable temperature;
• Always place babies on their back to sleep. Leave their head, face and arms uncovered during sleep;
• Babies do not need pillows. Place babies on a firm and well-fitted mattress to sleep. Avoid soft objects, pillows and loose bedding;
• Let babies sleep in a cot placed in the parents' room and near their bed; and
• Maintain a smoke-free environment.

 
     In addition, seasonal influenza vaccination is recommended for all persons aged 6 months or above except those with known contraindications. Persons at higher risk of getting influenza and its complications, including the elderly and children, should receive seasonal influenza vaccination early. Please see details of the vaccination schemes on the CHP's website.
      
     A person who gets influenza and COVID-19 at the same time may be more seriously ill and would have a higher risk of death. Influenza vaccination may reduce the likelihood of hospitalisation and the length of stay. It is important for elderly persons, especially those residing in residential care homes, to receive both seasonal influenza vaccination and COVID-19 vaccination. They should also receive an additional booster against COVID-19 according to recommendations as soon as possible. The public should also maintain good personal and environmental hygiene against respiratory illnesses and note the following:
 

• Surgical masks can prevent transmission of respiratory viruses from ill persons. It is essential for persons who are symptomatic (even if having mild symptoms) to wear a surgical mask;
• Wear a surgical mask when taking public transport or staying in crowded places. It is important to wear a mask properly, including performing hand hygiene before wearing and after removing a mask;
• Avoid touching one's eyes, mouth and nose;
• Wash hands with liquid soap and water properly whenever possibly contaminated;
• When hands are not visibly soiled, clean them with 70 to 80 per cent alcohol-based handrub;
• Cover the mouth and nose with tissue paper when sneezing or coughing. Dispose of soiled tissue paper properly into a lidded rubbish bin, and wash hands thoroughly afterwards;
• Maintain good indoor ventilation;
• When having respiratory symptoms, wear a surgical mask, refrain from work or attending classes at school, avoid going to crowded places and seek medical advice promptly; and
• Maintain a balanced diet, exercise regularly, take adequate rest, do not smoke and avoid overstress.

    
     Food-borne diseases, particularly those linked to hot pot cuisine, are also common in cold weather. The following preventive measures should be taken:
 

• Wash hands before handling and consuming food;
• Do not patronise unlicensed vendors or those with poor hygienic standards while selecting food;
• Wash and cook all food thoroughly;
• Vegetables should be washed thoroughly in clean running water before cooking and consumption. When appropriate, scrub vegetables with hard surfaces with a clean brush to remove dirt and substances, including pesticide residues and contaminants, from the surface and crevices;
• Shrimps should be fully cooked until the shells turn red and the flesh turns white and opaque;
• For shellfish such as scallops and geoduck, scrub the shells thoroughly and remove internal organs;
• Most hot pot ingredients should be stored in a refrigerator at 4 degrees Celsius or below, while frozen food should be stored in a freezer at -18 degrees C or below;
• Never use raw eggs as a dipping sauce for hot pot; and
• Use different sets of chopsticks to handle raw and cooked food to avoid cross-contamination.

     In addition, when using fuel-burning appliances, especially in indoor areas, the public should ensure adequate ventilation to avoid harmful exposure to carbon monoxide (CO) and prevent CO poisoning.

Attention duty announcers, radio and TV stations:

     Please broadcast the following special announcement immediately, and repeat it at frequent intervals when the Cold Weather Warning is in force:

     The Labour Department reminds employers that as the Cold Weather Warning is in force, they should take appropriate precautions such as reminding employees who have to work outdoors or in remote areas to wear appropriately warm clothing, and make arrangements for employees to rotate from outdoor to indoor or sheltered work sites as far as possible. Employees should take note of the weather report, wear appropriately warm clothing and be mindful of their health conditions. They should notify their supervisors and seek medical help immediately if feeling unwell, such as having cold limbs and body shivering.

     In response to the Japanese Government's plan to discharge nuclear-contaminated water at the Fukushima Nuclear Power Station, the Director of Food and Environmental Hygiene issued a Food Safety Order which prohibits all aquatic products, sea salt and seaweeds originating from the 10 metropolis/prefectures, namely Tokyo, Fukushima, Ibaraki, Miyagi, Chiba, Gunma, Tochigi, Niigata, Nagano and Saitama, from being imported into and supplied in Hong Kong.
 
     For other Japanese aquatic products, sea salt and seaweeds that are not prohibited from being imported into Hong Kong, the Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department will conduct comprehensive radiological tests to verify that the radiation levels of these products do not exceed the guideline levels before they are allowed to be supplied in the market.
 
     As the discharge of nuclear-contaminated water is unprecedented and will continue for 30 years or more, the Government will closely monitor and step up the testing arrangements. Should anomalies be detected, the Government does not preclude further tightening the scope of the import ban.
 
     From noon on February 6 to noon today (February 7), the CFS conducted tests on the radiological levels of 200 food samples imported from Japan, which were of the "aquatic and related products, seaweeds and sea salt" category. No sample was found to have exceeded the safety limit. Details can be found on the CFS's thematic website titled "Control Measures on Foods Imported from Japan" (www.cfs.gov.hk/english/programme/programme_rafs/programme_rafs_fc_01_30_Nuclear_Event_and_Food_Safety.html).

     The Agriculture, Fisheries and Conservation Department (AFCD) has also tested 52 samples of local catch for radiological levels. All the samples passed the tests. Details can be found on the AFCD's website (www.afcd.gov.hk/english/fisheries/Radiological_testing/Radiological_Test.html).
 
     The Hong Kong Observatory (HKO) has also enhanced the environmental monitoring of the local waters. No anomaly has been detected so far. For details, please refer to the HKO's website
(www.hko.gov.hk/en/radiation/monitoring/seawater.html).
 
     From August 24 to noon today, the CFS and the AFCD have conducted tests on the radiological levels of 29 631 samples of food imported from Japan (including 19 863 samples of aquatic and related products, seaweeds and sea salt) and 8 322 samples of local catch respectively. All the samples passed the tests.

     The effective exchange rate index for the Hong Kong dollar on Wednesday, February 7, 2024 is 104.9 (down 0.1 against yesterday's index).

     Hong Kong Customs detected two dangerous drugs trafficking cases from January 3 till yesterday (February 6). Suspected dangerous drugs worth about $12 million in total were seized. The seizures include about 40 kilograms of suspected cannabis buds, 3kg of suspected cocaine, about 200 grams of suspected crack cocaine, about 200g of suspected ketamine and a batch of drug packaging paraphernalia. Two men and a woman, suspected to be connected with the cases, were arrested during the operations.
      
     In the first case, through risk assessment, Customs on January 3 selected a seaborne consolidated consignment, declared as carrying pet foods and arriving from Thailand, for inspection at the Kwai Chung Customhouse Cargo Examination Compound. Upon examination, about 40kg of suspected cannabis buds was found mixed with the pet food goods. Upon a follow-up investigation, Customs officers conducted controlled delivery operations and arrested a 55-year-old male consignee who claimed to be a driver in Yuen Long on January 22. An investigation is ongoing.
      
     In the second case, Customs officers intercepted a 28-year-old woman during an anti-narcotics operation conducted in the vicinity of Po Fung Road, Tsuen Wan, yesterday evening and found about 50g of suspected crack cocaine inside a paper bag carried by her. She was then arrested. Customs officers later escorted the woman to a village house nearby for a search, and further seized about 3kg of suspected cocaine, 150g of suspected crack cocaine, about 200g of suspected ketamine and a batch of drug packaging paraphernalia therein. A 31-year-old man inside the premises, who was suspected to be connected with the case, was also arrested. The two arrested persons, who claimed to unemployed, have been jointly charged with one count of trafficking in a dangerous drug. The 28-year-old woman has been additionally charged with a count of trafficking in a dangerous drug. They will appear at the West Kowloon Magistrates' Courts tomorrow (February 8).
      
     Customs will continue to enhance enforcement against drug trafficking activities through intelligence analysis. The department reminds members of the public to stay alert and not to participate in drug trafficking activities for monetary return. They must not accept hiring or delegation from another party to carry controlled items in and out of Hong Kong. They are also reminded not to carry unknown items for other people, nor to release their personal data or home address to others for receiving parcels or goods.
      
     Under the Dangerous Drugs Ordinance, trafficking in a dangerous drug is a serious offence. The maximum penalty upon conviction is a fine of $5 million and life imprisonment.
     â€‹
     Members of the public may report any suspected drug trafficking activities to Customs' 24-hour hotline 2545 6182 or its dedicated crime reporting email account (crimereport@customs.gov.hk) or online form (eform.cefs.gov.hk/form/ced002).
