US President Joe Biden has invoked the Defense Production Act to boost the production of infant formula.
The Defense Production Act is a 1950 law that allows the government to direct manufacturing production for national defense.
This means companies supplying ingredients to formula makers will need to fill those orders first before fulfilling orders from other customers.
The White House will also allow flights to bring in supplies and preparations from other countries, as long as they meet US safety standards.
In a video on Twitter, Mr Biden said: “I know parents across the country are worried about finding enough infant formula to feed their babies.
“As a parent and grandparent, I know how stressful it is.”
Mr Biden said invoking the law would ensure that “manufacturers have the ingredients they need to make healthy and safe formulas right here at home”.
He added: “I have asked my team to do everything possible to ensure that there is enough safe infant formula and that it reaches the families who need it most quickly. one of my top priorities.”
The White House said, “Bypassing regular air cargo routes will expedite the importation and distribution of the formula and serve as immediate support as manufacturers continue to ramp up production.”
For months, the supply of infant formula in the United States has been affected by supply chain issues related to the pandemic, but in February a popular manufacturer had to close one of its facilities.
Abbott Laboratories closed its plant in Sturgis, Michigan, after recalling products following bacterial infections in four babies who received the formula.
Abbott denied any link between the formula and the diseases.
On Monday, the company said it reached an agreement with the US health regulator to resume formula production at the Michigan plant, but it will be weeks before new products start hitting stores.
