The Department of Justice (DOJ) has ended its criminal investigation into Abbott Laboratories' baby formula plant in Sturgis, Michigan, without filing any charges. This decision comes despite a substantial accumulation of evidence by prosecutors, which included internal company documents, communications, and inspection reports detailing unsanitary conditions and serious manufacturing deficiencies at the facility. The probe, which began in early 2022 following a widespread recall and a national baby formula shortage, examined whether Abbott or its executives should be held criminally responsible for introducing adulterated food into interstate commerce.

Evidence gathered during the investigation painted a concerning picture, with the Food and Drug Administration (FDA) having found "shocking" conditions such as cracks in vital equipment, inadequate hand-washing practices, and clear signs of previous bacterial contamination at the Sturgis plant. The plant was temporarily shut down in February 2022 after reports of bacterial infections in infants who had consumed products from the facility. Although the FDA and Abbott later reached an agreement to allow the plant to reopen, the Justice Department's complaint accompanying that civil agreement explicitly stated that Abbott and its employees had caused "adulterated food" to enter the market and demonstrated an unwillingness to implement sustainable corrective actions.

Despite the strong statements and evidence indicating serious problems, the DOJ ultimately concluded that it could not meet the high legal threshold required to prove criminal intent for the misdemeanor charges it was considering. This decision highlights the challenges in prosecuting food safety cases, where proving deliberate negligence or an intent to defraud can be difficult. The outcome has raised questions among some consumer advocates and legal experts about corporate accountability in cases of public health crises related to food manufacturing.
