A health educator with the Fond du Lac County Public Health Department says she is pleased to hear baby formula production has resumed at a troubled Michigan factory. Abbott Nutrition says baby formula production has resumed at the plant whose February shutdown over contamination contributed to a national shortage. Fond du Lac County Public Health Educator Rhianna Schmidt says it’s still going to take few weeks to get baby formula stocks back up. Abbott says EleCare, a specialty formula, is being made at Sturgis following a July 1 reboot and that Similac production will resume as soon as possible. Abbott is one of just four companies that produce 90 percent of U.S. formula.
