Both a national consumer's group and the Illinois attorney general are demanding a Food and Drug Administration recall.
But the federal agency is saying it had released inaccurate information on what chemicals were found in which top selling products.
The FDA reiterated its position that the baby food is safe and parents should continue feeding it to their babies.
At the same time, Illinois Attorney General Lisa Madigan called on the state's public health department and the FDA to recall both the Nestle and Mead Johnson products.
Madigan also criticized the FDA's handling of its test results.
