drug companies are located in the Medak district of Andhra Pradesh. This large concentration especially in Patancheru industrial zone, combined with lax oversight and inadequate water treatment, has left lakes (such as Kazhipally shown in the photo) and rivers laced with antibiotics, making this a giant Petri dish for anti-microbial resistance.
study conducted by scientists from Sweden's University of Gothenburg, on pollution in the area revealed antibiotic concentrations in effluent from a treatment plant used by drug factories were higher than would be expected in the blood of patients undergoing a course of treatment. That effluent was discharged into local lakes and rivers.
study by the same group reveals the polluted lakes harboured considerably higher proportions of ciprofloxacin-resistant and sulfamethoxazole-resistant bacteria than did other Indian and Swedish lakes included for comparison. These findings are disputed by local government officials and industry representatives.
Study published by researchers from the Indian Institute of Technology, Hyderabad, found very high levels of broad-spectrum antibiotics in the Musi, a tributary of the Krishna, one of India's longest rivers.
