Love to binge on pani puri? Beware, eating pani puri laden with artificial colours may increase your risk of various cancers and asthma amongst a host of other health issues, according to an expert on Tuesday.

Based on several complaints, Food Safety officials in Karnataka collected about 260 samples from roadside stalls. Of these, 22 per cent pani puris failed miserably at quality tests. About 41 samples contained artificial colours and cancer-causing agents, while 18 were found stale and unfit for human consumption.
