The Wall Street Journal reports Abbott Laboratories was alerted to problems at one of its infant formula plants months earlier than previously known. The journal reports an Abbott employee filed a complaint of failing equipment in need of repair and potentially unsafe formula back in February 2021. That’s a full eight months before another complaint was filed by the same person in October 2021, and a full year before the plant was shut down in February 2022. Abbott recently restarted production of some of its infant formulas at its Sturgis, Michigan, plant.
