The announcement comes after a popular food blogger launched a petition this week asking the sandwich chain to stop using the ingredient, called azodicarbonamide. A representative for Subway says the change was underway before the petition was launched, but did not immediately provide details on when it started or when it would be complete.
I'm impressed that this was only with a week of petitioning. There must have been enough other pressures though that it's been in the back of their minds for awhile.
Anyhow, it's promising that the customer still has some pull.
