28th February 2024 – (Hong Kong) The Centre for Health Protection (CHP), a division of the Department of Health, has provided an update on its ongoing investigations into suspected food poisoning clusters associated with Eihou Ryouri restaurant on Lockhart Road in Causeway Bay. Following the announcement made on 27th February, the CHP has identified four additional clusters, bringing the total number of affected individuals to 22. The CHP has urged the public to prioritise personal, food, and environmental hygiene to prevent the spread of foodborne diseases.

The newly identified clusters involve four males and seven females, ranging in age from 21 to 55. These individuals experienced symptoms such as abdominal pain, diarrhoea, dizziness, general weakness, nausea, and vomiting approximately 22 to 48 hours after dining at the restaurant between 24th and 26 February. While four of the affected persons sought medical attention, none of them required hospitalisation. Currently, all individuals affected by the suspected food poisoning are in stable condition.

To date, the CHP has recorded a total of six clusters connected to the restaurant, including those announced yesterday. Through epidemiological investigations, the CHP has determined that the affected individuals consumed a variety of common foods, including raw oysters and sashimi. Based on preliminary assessments, the clusters may have been caused by Vibrio parahaemolyticus and/or norovirus. In order to determine the exact source of infection, the CHP has collected stool specimens from the patients for testing.
