HHS to investigate FDA's handling of baby formula recall

What they're saying: "We will determine whether FDA followed the inspections and recall process for infant formula in accordance with Federal requirements," HHS' Office of the Inspector General said in a statement.

• The investigation will specifically look at whether the FDA's actions preceding the February recall at the Abbott facility followed the correct policies and procedures when conducting inspections at the facility and overseeing Abbott's initiation of the recall.

Catch up quick: Abbott — one of the largest suppliers of baby formula in the country — recalled several major brands of its formula back in February after federal officials investigated four babies who suffered bacterial infections from baby formula made at Abbott's factory in Sturgis, writes Axios' Herb Scribner.

• In mid-May, Abbott struck a deal with the FDA to reopen its facility and noted that an investigation involving the FDA, Abbott and the CDC found "no conclusive evidence to link Abbott's formulas to these infant illnesses."
