He said notices had been sent to the owners of erring food stores.
"Before filing a case against the defaulters, we have given them a month's time to move referral laboratory in Ghaziabad for their satisfaction. The reports of referral laboratory will be considered as final result," he added.
According to the Food Safety and Standards Act, a fine of Rs 1 to 5 lakh could be slapped on manufacturers or shopkeepers selling substandard edible items.
