Pesticides in Indian Milk

A 7-year study of pesticide residues in milk covering 12 Indian states has attrac-ted considerable public concern. The study, by the Indian Council of Medical Research (ICMR), found a high proportion of samples of milk foods—bovine, human and other—had residues of HCH and DDT above tolerance limits.

A number of prominent activists, scientists, social scientists and politicians were present at a meeting in July held to discuss the official report, Surveillance of Food Contaminants in India of 1993, prepared by the ICMR. The meeting, organised by an NGO in Delhi, was the brainchild of Maneka Gandhi (former Indian Environment Minister) who is known for her environmental and public interest work. Former Prime Minister VP Singh also attended the seminar (see photo).
   
The report was a result of seven years work covering 12 States, carried out at six prestigious government food testing labs (see PN 21 p. 10). The analysis covered bovine and infant milk foods which were analysed for DDT and HCH. For other food samples, analysis was extend to the presence of metals and aflatoxins. Unlike similar government reports, this document was widely circulated and had attracted considerable public attention locally, especially as it concerned milk—an important source of nutrition especially for the young and elderly. Milk is also rated very highly amongst vegetarians (over 50% of the 800 million population) and is often taken during illness and convalescence.

The results
Dr GS Toteja, who summed up the ICMR report assessing residues in milk and infant foods, pointed out that from 2,205 samples of bovine milk 85% of the milk samples contained HCH isomers (alpha, beta, gamma or delta) above the tolerance limits. In the case of gamma-HCH, 28% of samples were above the tolerance limit of 0.01 mg/kg as set out under the Prevention of Food Adulteration Act on a whole milk basis. In the case of DDT, 82% of the milk samples were contaminated, about 37% of these above the tolerance limit of 0.05 mg/kg on a whole milk basis.
    The highest HCH contamination was in the State of Andhra Pradesh, followed by Bihar and Uttar Pradesh. In Maharashtra, 74% of DDT samples exceeded the upper limit. Of the 186 samples of baby foods (of 20 commercial brands), DDT was present in about 70% of the samples and HCH in 94%. Out of 32 Indian states, 25 had not been taking residue samples from milk.

No prosecutions/no limits
It was observed that there had been no prosecutions or warnings issued since permissible limits were introduced in 1968. It also emerged that no pesticide limits had been set for animal feedstuff, water, air or soil.

Recommendations
The seminar adopted a 10 point resolution pointing out the intolerable level of pesticides in milk, the dangers to health and general apathy from officialdom—particularly regarding research and development into alternatives to dangerous pesticides. Concern was expressed for the environment—protecting the generations to come. In this respect, farmers and NGOs should be supported in taking up sustainable ecological farming. A call was made to set up a Watchdog Task Force to take up these issues.
