"We want our customers and consumers to know that we are continuing to work day and night with the FDA and other officials to determine the source of the problem and ensure that it never happens again," the company added.
But Rep. John Dingell, D-Mich., said the FDA is in such desperate need of money, personnel and authority that something like this could happen again unless the government strengthens the nation's food safety system. Dingell cited a slew of problems that have recently faced the FDA as evidence the agency is not up to the job.
"Go and tell the people who got sick or died from salmonella and peanuts," Dingell told ABC News on Friday. "Go and tell those who have gotten unsafe seafood or shellfish from China. Go and tell those who got heparin or other bad pharmaceuticals from China about how wonderful a job Food and Drug is doing, then come back and tell me how they feel about it."
"Until Congress acts, until this administration undoes some of the doings of the prior administration, I think you can look forward to more scandals of this kind," Dingell said.
President Obama has said before that food safety concerns will be addressed by the new administration.
"When I am president, it will not be business as usual when it comes to food safety," Obama said last year in response to meat from sick cows being sold to the school lunch program. "I will provide additional resources to hire more federal food inspectors."
"As the parent of two young daughters, there are few issues more important to me than ensuring the safety of the food that our children consume," Obama said.
Michael Taylor, professor at George Washington University's School of Public Health, said companies should be required to put a system in place to ensure food safety because right now, there is "no comprehensive prevention system."
"This case was so egregious it should have been caught," Taylor said.
