Heavy Met­als

Consumer Voice - - Curd (dahi) -

Heavy met­als such as arsenic, lead and mer­cury are toxic or poi­sonous when these ac­cu­mu­late in the body due to ex­po­sure through food or wa­ter. These should not be present in higher than the lim­its spec­i­fied in the na­tional stan­dards. We tested the 12 brands for pres­ence of arsenic and lead. • For arsenic, the spec­i­fied limit for curd is a max­i­mum 1.1 ppm (mg/kg) as per FSS Reg­u­la­tions. Arsenic was

not de­tected in any of the tested brands, the de­tec­tion limit be­ing 0.05 mg/kg. • For lead, the spec­i­fied limit for sec­ondary milk prod­ucts (curd is one) is 0.02 ppm (mg/kg) as per FSS

Reg­u­la­tions. Lead was not de­tected in any of the brands. Lead is ex­tremely toxic to hu­mans and af­fects the liver, kid­neys, re­pro­duc­tive sys­tem and ner­vous sys­tem. Lead ex­po­sure can hap­pen qui­etly and causes per­ma­nent prob­lems, es­pe­cially to the brain. Ex­po­sure to small amounts of lead over a long pe­riod of time is called chronic tox­i­c­ity. Lead is par­tic­u­larly dan­ger­ous be­cause once it gets into a per­son’s sys­tem, it is dis­trib­uted through­out the body just like help­ful min­er­als such as iron, cal­cium and zinc. And lead can cause harm wher­ever it lands in the body.
