"We are yet to receive any notice. Once we receive the notice, we will reply to it at the earliest. We want to say we have not flouted any norms, rules or regulations of FSSAI," Ramdev said on the sidelines of a programme here.
"We have followed all the rules and regulations of FSSAI. We have not done anything illegal."
The Ramdev-promoted Patanjali came out with 'atta noodles' earlier this week in 70-gram packs priced at Rs 15, claiming it to be cheaper than those from its competitors, with an aim to take on the market leader, Nestle.
Nestle's Maggi is now back on shelves five months after FSSAI had banned it.
