The Centre for Health Protection (CHP) of the Department of Health is today (January 19) investigating an outbreak of food poisoning affecting 11 persons, and reminded the public to maintain personal, food and environmental hygiene to prevent food-borne diseases.

The patients, comprising one man and 10 women aged 63 to 76, developed abdominal pain, nausea, vomiting, diarrhoea and fever about 12 to 26 hours after having lunch at a restaurant at Lau Fau Shan in Yuen Long on January 7.

Five of them sought medical attention, of whom one required hospitalisation but was discharged upon treatment. The stool specimen of that patient tested positive for Vibrio parahaemolyticus. All affected persons are now in stable condition.
