The Centre for Health Protection is investigating two reports of suspected food poisoning outbreaks involving 17 people upon notification by the Guangdong Department of Health.
The affected people, five men and 12 women, aged 24 to 69, were among two tour groups to Shaoguan in Guangdong Province.
A group of 15 people had breakfast at a hotel in Shaoguan on September 22. Five of them, a man and four women aged 40 to 52, developed gastrointestinal symptoms including diarrhea, abdominal pain and vomiting 4.5 to seven hours afterwards.

They sought medical treatment from the Accident & Emergency Department of North District Hospital upon returning to Hong Kong. All are in stable condition and no hospitalisation was required.
Another group of 34 people had breakfast at the same place on September 22. Twelve of them, four men and eight women aged 24 to 69, developed gastrointestinal symptoms including diarrhea, abdominal pain and vomiting two to 13.5 hours afterwards.
Some of them sought medical treatment at a local hospital. All are in stable condition and no hospitalisation was required.
Initial investigations suggested that bacteria were likely to be the causative agent of the outbreaks.
