A 33-year-old woman died and 20 others suffered food poisoning after eating momo served by a street vendor at different locations in Hyderabad’s Banjara Hills area, police have said.

Ram Babu, Sub-inspector of Banjara Hills Police Station, told news agency PTI, “We received a complaint yesterday that Reshma Begum (33) died and 15 others suffered food poisoning after consuming memos (street food) from a single vendor at different locations. We have registered a case and are investigating the matter.”

An investigation has found that the vendor was operating without any food safety licence and that food was being prepared in unhygienic conditions. The dough used to prepare momos was placed in the refrigerator without any packing, the probe found. It also found that the refrigerator door was broken.

Samples from the food vendor have been sent for lab analysis. The vendor’s owner has been asked to immediately suspended the food business and a criminal case will be filed under the Food Safety and Standards Act.
