Pesticide tests on Thai fruit show red grapes, dates high in chemical contamination
The Department of Agriculture has ordered an investigation after tests by the Thai Pesticide Alert Network (ThaiPAN) found worrying levels of chemical contamination in fruits and vegetables on sale in markets and malls.
All 30 random samples of red grapes and dates exceeded the maximum residue level (MRL) permitted, while pomelo was the only product found to be safe from chemical contamination.
ThaiPAN tested 509 samples of fruit and vegetables – 201 from six malls and 308 from 10 markets. Among them were locally produced products as well as imports, both certified and non-certified.
In response to the test results, Department of Agriculture director-general Pichet Wiriyapaha has ordered officials to conduct inspections on supermarket fruit and vegetables labelled Organic Thailand, Q GAP, Thai GAP, PGS, or with foreign organic standards. If any are found to exceed maximum residue levels, the relevant certification authority will be told to alert the farmers, he said.
If banned chemicals are found, officials will revoke certification, Pichet added.
He said the department was currently developing biological substances and plant extracts to replace agrochemicals.
“At present, 17 types of biofilms are recommended for farmers to use as part of Good Agricultural Practices [GAP] to kill pests in organic farming systems.”
Registration guidelines for the use of biological and plant extracts to eliminate weeds will be offered soon, he said.
Meanwhile the Agriculture and Cooperatives Ministry and the Food and Drug Administration (FDA) under the Public Health Ministry will collaborate on their own inspections of chemical contamination in fruits and vegetables.
