What are pesticides ?
Pesticides are chemical or biological substances that are used to kill or control pests that harm our food, health or environment. They are usually used in food production because pests can have devastating effects on the quantity and quality of crops. Pests include rodents, insects, fungi and plants. In Hong Kong, only officially approved pesticides may be used. Plant growth regulators, which are used to influence particular growth processes in plants (for example, slowing down the growth of sprouts on potatoes) are also regulated as pesticides.
What are pesticide residues?
Pesticide residues are the very small amounts of pesticides that can remain in or on a crop after harvesting or storage and make their way into the food chain. Pesticide residues also include any breakdown products from the pesticide.
Pesticide residues can remain even when pesticides are applied in the right amount and at the right time. Sometimes they need to stay on the crop to do their job. For example, they may need to be on the surface of a fruit or vegetable to protect it from pests during storage. Some pesticides are applied after harvest for this purpose.
Pesticide Residues in Food Regulation
In Hong Kong, the “Pesticide Residues in Food Regulation (Cap. 132CM)” has been released on June 2012. The Regulation will come into operation on 1 August 2014 after a two-year grace period. Under the regulation, the presence of any listed pesticide residues in food at levels exceeding the Maximum Residue Limits (MRLs) and Extraneous Maximum Residues Limits (EMRLs) will be an offence.
