Why would pesticide residues appear in food?

The Pesticide Residues in Food Regulation (Cap. 132CM) will come into operation on 1 August 2014. You may wonder why pesticide residues would appear in our food. In fact, pesticides have a role to play in food security. In general, they are applied to prevent and control crops infestation. Proper use of pesticides can reduce crop damage by pests and increase the crop yield. Small amounts of pesticides may remain in crops following its application under Good Agricultural Practice (GAP) or as a result of environmental contamination. In general, the levels of pesticide residues in food should be low and do not pose health concern if GAP has been followed. With proper use of pesticides, consumers can enjoy a large variety of safe and wholesome produce, which is pest- and disease-free.
