The Chennai Corporation has started lifting samples of soft drinks from shops in various parts of the city for analyses.
This follows a report from its laboratory on Friday that a bottle of Coca Cola was contaminated with rodent excreta.
The person who lodged a complaint with the civic body alleged that on consuming the soft drink he found the taste different and examined the bottle.
He allegedly found some foreign particles in the bottle. Following his complaint, the sample was sent to the civic body's laboratory for analysis.
On confirmation of the contamination, the shop on Mallan Ponnappan Street in Triplicane was sealed by the Chennai Corporation on Friday.
The Health Department officials of the civic body are examining the reasons for the presence of rodent excreta in a branded product. They added that they would conduct investigations to ascertain whether the Coca Cola bottle and content was original.
Chennai Corporation Health Officer P.Guganantham said spurious products were being filled in empty bottles of branded soft drinks by local retailers in various localities in the city such as Triplicane.
The civic body on Saturday raided 25 shops on Triplicane High Road, Dr. Besant Road, Radhakrishnan Salai, Sivaswamy Salai, Wallajah Road, Bells Road and Llyods Road.
Over 245 bottles of soft drinks, that were believed to be unfit for consumption, were seized. Shops on the Marina Beach were also raided.
