Ambassador Mohamed Alhakim said he conveyed the information to the United Nations after speaking with his government in Baghdad yesterday.
"There is really no evidence that Daesh has used this chemical weapon," Alhakim told reporters ahead of a Security Council meeting on Iraq. Daesh is the Arabic acronym for the Islamic State (IS).
The Red Cross had reported that seven people, five of them children, had been hospitalised near Mosul in early March suffering from exposure to a chemical agent.
Iraqi forces launched an operation to retake west Mosul, the largest population centre still held by the jihadists, on February 19.

Alhakim said Iraq had been in contact with The Hague-based Organisation for the Prohibition for Chemical Weapons (OPCW), which could dispatch a team of experts in the event of a suspected toxic gas attack.
Following the closed-door Security Council meeting on Iraq, British Ambassador Matthew Rycroft said the Iraqi investigation of the alleged chemical attacks had not been completed and that the council had expressed concern.
