Chapter synopsis: Tea growers require pesticides to prevent crop loss due to pest attacks, which are aggravated by climate change. As pesticides invariably leave residues, it is of utmost importance that samples of traded tea are monitored to ensure compliance to food safety standards. This chapter reviews research into the extent of pesticide residues in tea, conventional methods for determining trace levels of multiple residues in tea and the problems with these methods and advanced, rapid methods which are more suitable for ensuring food safety. We also consider food safety standards in the EU and Japan, methods of assessing the risk posed by pesticide residues and strategies for reducing the residues in tea.
