Eight artificial dyes will be banned from medications and the nation's food supply by the end of 2026, Health Sec. Robert F. Kennedy Jr. said.

California fast food staple In-N-Out announced changes to some of its menu items, notably removing the food dye Red 40 from its pink lemonade.

The burger chain said in a Facebook post that it has replaced Red Dye 40 with beta carotene and vegetable juice in its strawberry shakes and "Signature Pink Lemonade."

The company confirmed the changes in a statement provided to USA TODAY May 15.

"We strive to have the best and be the best in all areas. It's been my family's priority since 1948, and it remains my priority to this very day," Lynsi Snyder, owner and president of In-N-Out Burger, said in the statement.

Health Secretary Robert F. Kennedy Jr. and the Food and Drug Administration announced a "mutual understanding" with the food industry in April that says eight food dyes, including Red Dye 40, will be progressively removed. In-N-Out did not reference the so-called agreement in its statement.

The company also said it is transitioning its ketchup from using high fructose corn syrup to cane sugar and is researching oil options for its fries.

The company operates 420 locations across eight states.
