CHP investigates case of Shiga toxin-producing E. coli infection
The Centre for Health Protection (CHP) of the Department of Health is today (October 15) investigating a case of Shiga toxin-producing Escherichia coli (STEC) infection, and hence reminded the public to maintain good personal, food and environmental hygiene against intestinal infections.
The case involves a 47-year-old male with good past health, who presented with abdominal pain and diarrhoea on September 23. He attended Hong Kong Sanatorium & Hospital (HKSH)on September 26, September 27 and October 3. His condition was stable and did not require hospitalisation.
His stool specimen grew STEC upon laboratory testing.
Initial enquiries of the CHP revealed that the patient had travelled to the Mainland during the incubation period. His travel collateral has remained asymptomatic so far. Information from the patient revealed that he did not consume any high-risk food (such as raw meat and unpasteurised dairy products) during the incubation period. As the patient worked at the HKSH Canteen (address: 4/F, Li Shu Pui Block, HKSH, Happy Valley) and was responsible for handling siu mei, the CHP is contacting other relevant staff members of the restaurant to follow up their health conditions.
Symptoms of STEC infection include abdominal cramps and diarrhoea that may in some cases progress to bloody diarrhoea. Fever and vomiting may also occur.The CHP appealsto persons who have patronised the above restaurant from September 23 onwards and have experienced relevant symptoms to seek medical attention immediately.
The investigations of the CHP are ongoing.
"Escherichia coli (E. coli) is a bacterium that is commonly found in the gut of humans and warm-blooded animals. Most strains of E. coli are harmless. Some strains, however, such as STEC, can produce powerful toxins and cause severe food-borne disease. The most recognised serogroup of STEC is E. coli O157:H7," a spokesman for the CHP explained.
Preventive measures for STEC infection are similar to those recommended for other food-borne diseases. The public are advised to observe good personal and food hygiene:
- Adopt the Five Keys to Food Safety in handling food, i.e. Choose (choose safe raw materials), Clean (keep hands and utensils clean), Separate (separate raw and cooked food), Cook (cook thoroughly) and Safe Temperature (keep food at a safe temperature) to prevent food-borne diseases;
- Wash hands properly with liquid soap and water before handling food, after handling raw meat or poultry and before eating, and after going to the toilet or changing diapers;
- Cook food and boil water thoroughly before consumption. When cooking or reheating, the core temperature of the food should reach at least 75 degrees Celsius;
- Avoid consumption of unpasteurised milk or undercooked food; and
- Consult your doctor immediately if you have symptoms of STEC infection, particularly bloody diarrhoea.

Suspected use of fraudulent life-saving attendant certificate at private housing estate's swimming pool in Happy Valley
A spokesman for the Food and Environmental Hygiene Department (FEHD) said today (August 6) that a life-saving attendant at the licensed swimming pool of a private housing estate, located at 1-5 Ventris Road, Happy Valley, is suspected of using a fraudulent life-saving attendant certificate. As the qualification of the life-saving attendant is in doubt and the swimming pool has allegedly failed to provide a sufficient number of qualified life-saving attendants as required by law, the FEHD has ordered the immediate closure of the pool and is considering prosecuting its licensee. The incident has been reported to the Police, and the FEHD has also notified the Property Management Services Authority to take parallel follow-up action.
Officers from the FEHD yesterday (August 5) verified a batch of lifeguard records with the Hong Kong China Life Saving Society (HKCLSS), and received the verification result today. It is discovered that the credentials of a life-saving attendant on duty at the aforementioned swimming pool yesterday did not match the records of the HKCLSS. The FEHD immediately took action regarding the pool.
The spokesman stressed, "Swimming pool licensees must strictly comply with the Swimming Pools Regulation (Cap. 132CA) and the licensing conditions, ensuring that sufficient qualified life-saving attendants are on duty during the opening hours of the pool. The FEHD will continue to implement various regulatory measures, including stepping up surprise inspections and increasing the frequency of spot checks during the peak swimming season."
Since May 2025, the FEHD has implemented a series of enhancement measures, including stepping up surprise inspections, clearly stipulating the responsibility of licensees to verify the qualifications of life-saving attendants, introducing a tiered penalty mechanism, and strengthening collaboration with relevant organisations. From January to the end of July this year, officers from the FEHD had conducted about 7 000 inspections of over 1 400 licensed private swimming pools across the territory, and had verified the qualifications of about 2 100 life-saving attendants through the HKCLSS. According to the records, since the implementation of enhanced regulatory measures in 2025, the FEHD also discovered a case involving the suspected employment of unqualified life-saving attendants on duty in 2025.
To ensure that licensees fulfil their responsibilities properly, the FEHD explicitly requires them through licensing conditions to verify the identity documents of life-saving attendants before employment, and to keep copies of their Pool Lifeguard Awards and personal logbooks on proper record. The FEHD has also established a standard template of life-saving attendants' duty records. Licensees are required to clearly record the relevant information of life-saving attendants on duty in accordance with the prescribed format, and the records have to be verified and signed by both the inspecting staff assigned by the licensees and the life-saving attendants. FEHD officers will check the relevant records as necessary during inspections or complaint investigations, and will follow up on any violations.
In addition, the FEHD will continue to maintain close collaboration with relevant organisations and regulatory bodies to enhance compliance with the regulatory measures. This includes sustaining close liaison with the HKCLSS and making good use of its mechanism for verifying life-saving attendants' qualifications, and strengthening co-operation with the Property Management Services Authority to require property management companies to exercise strict gatekeeping over the recruitment procedures of life-saving attendants.
The FEHD will continue to implement the relevant measures straightly to enhance the safety standards of licensed swimming pools and safeguard the safety of swimming pool users. Members of the public are called on to take part in the monitoring and report suspected cases of irregularities to the department.
