In order to understand the pesticide residues in tea leaves, herb tea and tea beverage, 100 tea and 33 herb tea specimens were sampled by local health personnel from tea retailers and 30 samples of tea beverage were purchased from convenience stores from March to May in 2006. Samples were analyzed by the modified multi-residue methods in food, which were proclaimed by the Department of Health, to determine 135 types of pesticide. One (3.0%) herb tea specimens was found to contain carbaryl (1.2 ppm) and chlorpyrifos (6.5 ppm) that were not allowed in herb tea according to the Regulation of the Department of Health. The overall non-compliant rate was 0.6% in 163 of samples. Penalty was enforced by the local authority according to the Food Sanitation Management Act.
