"As part of FDA's overall commitment to ensure the safety of the food supply, the agency uses an extensive, science-based process to evaluate the safety of food additives," FDA spokeswoman Theresa Eisenman said. "Under FDA regulations, safety for food additives means that there is a reasonable certainty of no harm when an additive is used within the intended conditions of use."
Eisenman told ABCNews.com that the FDA is currently collecting data on the use of azodicarbonamide in bread.
"The agency continues to monitor the safety of food additives, including azodicarbonamide, and is prepared to take appropriate action if there are safety concerns," she said.
Meanwhile, Stier agrees that "it's appropriate that we should be concerned about what's in our food."
"That's why we have risk assessment and toxologists and career scientists at the FDA," he said. "And if Sen. Schumer wants to make the argument that it's the Bush administration's propensity for industry, these are Obama scientists. This is not the way to develop food policy."
Stier said both Subway and Schumer had agendas.
"Subway is trying to position itself as a healthy fast food company," he said. As for Schumer, "He gets headlines from it and gets his name out there. What he doesn't realize is that if we use his standards, he'll put New York businesses out of business."
