The Whataburger and Raising Cane's chains removed white buns and Texas toast from some restaurants Wednesday as a bun and bread crisis continues to plague Texas restaurants.
An "unbalance in the yeast" affected the hamburger buns' flavor, and Whataburger recalled them from the Dallas-Fort Worth area, Texas, Oklahoma and Arkansas, according to a statement from the San Antonio-based Whataburger corporate office.
According to a KXAS/Channel 5 report, Louisiana-based Raising Cane's did not cite a reason other than to say the toast "did not meet our high quality standards."
Whataburger stores are open and continue to serve burgers and sandwiches on wheat buns, tortillas or as a bunless platter, the company statement said.

The announcements came the same day as Texas locations of California-based In-N-Out Burger reopened after closing two days to replace a batch of buns.
"There's no health risk at all, rather an impact on our bun's flavor," the corporate statement read.
Whataburger also extended breakfast hours until 1 p.m. Wednesday as an alternative, the company said.
Patrons commenting on social media said they were told only that the location was out of white buns.
Some locations posted a letter saying that "due to a quality issue," the restaurant was not serving either its signature 5-inch white buns, 4-inch white buns or Texas toast.
No date was given for white buns to return: "The company looks forward to getting back to business as usual just as soon as we can."
Patrons of Whataburger and In-N-Out, both privately owned and each with its own fan following, had exchanged barbs online after the Texas In-N-Out locations closed Monday and Tuesday, citing only an undisclosed problem with bun quality.
