These regulations are based on international guidelines set by organizations like the Codex Alimentarius commission and the Food and Agriculture Organization (FAO).
Key aspects of Hong Kong’s pesticide regulations include:
- Maximum Residue Limits (MRLs): Specific MRLs are established for various pesticides in different food commodities.
- Import Controls: Food imports are subject to inspection and testing to verify compliance with MRLs.
- Local Production Monitoring: The CFS monitors pesticide use in local agricultural production.
- Risk Assessment: Regular risk assessments are conducted to evaluate the potential health risks associated with pesticide exposure.
