Bread samples of virtually all top brands in Delhi contained cancer-causing chemicals, a study released today said, prompting the Union Health Ministry to order a probe.
Nearly 84 percent of 38 commonly available brands of pre-packaged breads including pav and buns, tested positive for potassium bromate and potassium iodate, banned in many countries as they are listed as "hazardous" for public health, the report by Centre for Science and Environment (CSE) said.
It claimed that while one of the chemicals is a category 2B carcinogen (possibly carcinogenic to humans), the other could trigger thyroid disorders but India has not banned their use.
The bread samples which were tested included brands such as Britannia, Harvest Gold and the fast food chains – KFC, Pizza Hut, Domino's, Subway, McDonald's and Slice of Italy.
Britannia, KFC, Domino's, McDonald's and Subway denied that these chemicals were used in their products. Other brands did not comment despite repeated attempts.
Reacting to the CSE report, Health Minister J P Nadda said, "We are seized of the matter. I have told my officials to report to me on an urgent basis. There is no need to panic. Very soon we will come out with the (probe) report."
CSE's Pollution Monitoring Laboratory (PML) tested 38 commonly available branded varieties of pre-packaged breads, pav and buns, ready-to-eat burger bread and ready-to-eat pizza breads of popular fast food outlets from Delhi.
"We found 84 per cent samples positive with potassium bromate or iodate. We re-confirmed the presence of potassium bromate or iodate in a few samples through an external third-party laboratory. We checked labels and talked to industry and scientists.
