So many as 20 samples of different food items failed laboratory tests in October and November.
Presenting the figures, district health officer Surinder Singla said that they had collected around 109 food samples in the past two months, out of which 20 samples of clarified butter (desi-ghee), ice creams, red chillies and bread pakoras failed the tests.
Singla said they had sent the cases to the additional deputy commissioner for further action against the offenders.
Till September, the health department had collected nearly 407 food samples, out of which 54 had been found substandard in quality.
Singla also directed the food items retailers to get their licenses as per the new guidelines of the Food Safety and Standard Act before February 4.
He said that under the Act a fine of Rs. one to five lakh could be slapped on manufacturers or sellers doling out substandard edible items.
"Raids will be conducted in the future and strict action would be taken against the offenders," he added.
