FAQ
Must Hong Kong restaurants install grease traps before opening?
Yes. Per DSD regulations, all food premises must install compliant grease traps and submit installation proof when applying for food licences. Premises without grease traps will not be licensed.
How often should grease traps be cleaned?
Generally at least weekly; high-grease kitchens like hot pot or fried chicken shops should clean every 3-4 days. Regular cleaning prevents blockages and odour issues and ensures proper system function.
