  1. Generally speaking, to reduce pesticide residues in vegetables, members of the public can rinse vegetables thoroughly under clean running water, and scrub produce with hard surfaces with a clean produce brush to remove dirt and substances including pesticides and contaminants from the surface and the fissures, when appropriate.
  2. Any person who imports, manufactures or sells any food not in compliance with the requirements of the Pesticide Residues in Food Regulation (Cap 132CM) concerning pesticide residues commits an offence and is liable to a maximum fine of $50,000 and to imprisonment for six months upon conviction.
  3. The CFS will follow up on the unsatisfactory result, including advising the vendor concerned to stop selling the food in question, tracing the source and distribution of the food in question and taking samples for testing.
