Abbott says it will continue to "leverage" its supply network in Cootehill to address severe baby formula shortages in the US.
In a statement to Northern Sound, an Abbott spokesperson said the company "understands the situation is urgent".
Its plant in Michigan in the US is closed following a federal investigation, after it recalled three baby-formula products amid reports of infant illness.
Two of the infants have since died, but Abbott says "after a thorough review of all available data, there is no evidence to link our formulas to these infant illnesses".
The statement added that "subject to FDA approval, Abbott could restart the site within two weeks".
From the time Michigan site restarts, the Abbott spokesperson says "it will take six to eight weeks before the baby formula product is available on shelves" in the US.
