If you feel that your neighbourhood store is adulterating your food but cannot confirm it, then head to the NGO Hall in Cubbon Park, where a National Agmark Exhibition is under way.

From simple home tests to complicated microbial tests in accredited laboratories, the exhibition showcases and demonstrates ways to check for adulteration.

“Children are attracted by colours, and most of the colours used in food products are extremely harmful to health,” an employee of a Bruhat Bangalore Mahanagara Palike food laboratory told a group of women gathered around the stall.

With samples of such adulterated food products on display, the group listened attentively as the employee explained home-based checks for food products.

“More elaborate tests will be conducted in laboratories. You can either complain to BBMP health officials or pay a fee of Rs. 300 and get products tested at Bruhat Bangalore Mahanagara Palike laboratories,” she added.

Besides laboratories, a host of companies are participating in the exhibition to showcase their products.

“This is an eye-opener to some of us,” said Sujatha, a homemaker from Jayanagar who was at the exhibition with some of her friends.

The four-day exhibition was inaugurated on Wednesday by S.K. Bellubbi, Minister for APMC, Haj and Wakf.

The National Agmark Exhibition will end on February 16.
