If the food consumed at a food premise is unsanitary

thermostat

The food and Environmental Hygiene Department (FEHD) is responsible for overseeing that the food sold in Hong Kong is safe, hygienic, and fit for human consumption.  

Members of the public may lodge a complaint to FEHD if the food consumed at a food premise is unsanitary or contains substances not suitable for human consumption. Members of the public should seek for medical treatment as soon as possible if they feel unwell after eating.  If the case is confirmed by medical officers as food poisoning, the clinic or hospital will report the case to FEHD and the Centre for Health Protection for follow-up actions and investigation.   

Members of the public may contact FEHD 24-hour Hotline 2868 0000 (which is handled by “1823”) if they want to lodge food complaints.  The complaint cases will be handled by duty FEHD health inspector(s).  The health inspector(s) will contact the complainant and advise him or her on how to handle the food exhibit.  If the complainant would like to wait for the health inspector(s) at the concerned food premise, please note that the waiting time will depend on the situation, and please ask the health inspector(s) for details.

After conducting an initial investigation, the Food Surveillance and Control Division of FEHD will contact the complainant if necessary.
Food premises may be prosecuted by FEHD if they violate public health ordinance or even if the license is revoked.
