Study finds high levels of pesticide residue in vegetables sold as organic in the city
“Organically grown” is the watchword these days. The
scare created by the high levels of pesticides in vegetables available
in the market has people scampering to buy anything with the ‘organic’
label. Unfortunately, in many instances, the label ‘organic’ might not
even worth the paper on which it is printed.
A
sample study of the ‘organic’ vegetables collected from a few shops
selling organically grown produce in the city, by the Pesticide Residue
Research and Analytical Lab of the College of Agriculture, Vellayani,
has found many ‘organic’ vegetables are as contaminated with pesticide
residues as the ones in the general market.
The
latest findings from samples collected in August-September were revealed
at a seminar on Safe Food Business Practices organised by the
Commissionerate of Food Safety here on Wednesday.
“We
had identified 14 items of vegetables in the general market as heavily
contaminated. Some – curry leaves, mint and coriander leaves, green
chilli, okra (lady’s finger), capsicum, carrots, snake gourd – with the
organic label were found to be contaminated with the same pesticides,
indicating that these are also probably sourced from the same producer
or agent,” says Thomas Biju Mathew, professor, KAU, who has taken up the
periodical analysis of vegetable sample as part of a project funded by
the Agriculture Department.
The pesticide
contaminants found in the ‘organic’ vegetables were Profenaphos and
Bifethrin, for both of which, no maximum residue limit (MRL) has been
fixed by the Food Safety and Standards Authority of India. Hence the
samples were compared with the MRL fixed by the European Union for these
pesticides.
Dr. Mathew said there was no point in
blaming shopkeepers because there was no sure-fire way of identifying
pure organically grown vegetables. It was difficult and not viable for
farmers to produce vegetables for mass consumption without using
pesticides at all. Creating more awareness among farmers on the
judicious use of pesticides and giving adequate withdrawal period for
pesticide residues to vanish before harvesting the produce might be the
only practical solutions.
Case of cardamom
Thomas
George, Associate Professor, KAU, in his presentation on pesticide
residues said that cardamom was one of the most highly contaminated
produce in the State. Every farmer seemed to use at least at least four
pesticides for the crop. The levels of pesticide residues in cardamom
had been going up in recent years and in some samples tested by KAU, a
cocktail of residues of 12 pesticides had been found. Quinalphos,
belonging to the organophosphates group, was the biggest contaminant in
cardamom, followed by profenophos, methyl parathion and triazophos.
However,
almost 80 per cent of the pesticide residues in cardamom were limited
to the outer pod of the spice. Using just the seeds was a safer option.
The seminar discussed the safety of meat and dairy products, trans fat
content in bakery goods, and the microbial quality of various
ready-to-eat food items in the market.
Health
Minister V.S. Sivakumar inaugurated the seminar. Commissioner of Food
Safety Biju Prabhakar; Joint Commissioner K. Anilkumar; and Mayor K.
Chandrika spoke.
