Abbott Nutrition, the country’s largest producer of baby formula, has been cleared to resume production at its Michigan plant.

The company announced the news in a statement Saturday, nearly three months after it was forced to shutter the factory due to contamination concerns. Around that time, Abbott issued a product recall of its Similac, Alimentum and EleCare powdered infant formulas, all of which were produced at the Michigan plant and consumed by babies were contracted bacterial infections. Two of those babies died from the illness.
