PORTLAND, OR - MAY 12: Katie Wussler, a program coordinator at Mother & Child Education Center, throws away recalled Similac baby formula, which the company would not replace or reimburse because the donated supplies did not come with a receipt, on May 12, 2022 in Portland, Oregon. More than 60 percent of Mother & Childs formula supply was affected by the recall, and like many similar non-profits they are struggling to meet increased demand from mothers who are unable to find or afford formula in stores. Executive Director Maura White said she's had to turn away mothers looking for formula about three times a week since the recall was announced. (Photo by Nathan Howard/Getty Images)

WASHINGTON (AP) — The Senate has approved a bill aimed at easing the baby formula shortage for families participating in a government assistance program known as WIC. That program accounts for about half of all formula purchases in the U.S. The House had passed the bill the day before, so it now goes to President Joe Biden to be signed into law. The vouchers can generally only be used to purchase one brand of infant formula, which encourages the manufacturer to offer big discounts to secure a state’s business. The bill makes it possible for families to redeem the WIC vouchers for whatever formula brand is available.
