More than 500 people have been sickened and at least eight may have died. Authorities fault Peanut Corp. of America. Officials said the company shipped products that initially tested positive for salmonella after retesting and getting a negative result.

The outbreak has led to a massive recall of products ranging from ice cream to cookies and prompted consumer groups to urge Congress to require annual inspections of food processing plants.

"I think that the FDA has not been able to catch some of these things as quickly as I expect them to catch," Obama said in an interview aired Monday on NBC's "Today" show. "And so we're going to be doing a complete review of FDA operations."

The president said Americans should be able to count on the government to keep children safe when they eat peanut butter and that includes his 7-year-old daughter Sasha.

"That's what Sasha eats for lunch probably three times a week. And you know, I don't want to have to worry about whether she's going to get sick as a consequence to having her lunch," Obama said.

The FDA has asked the Justice Department to launch a criminal investigation into Virginia-based Peanut Corp. of America. Documents showed that until shortly before the salmonella outbreak, federal food safety inspectors had not been to the plant since 2001.

"The FDA is supposed to be a watchdog for consumers, and for too long, this agency has been coming up short," said Jean Halloran, director of Food Policy Initiatives for Consumers Union.
