WASHINGTON—U.S. regulators have historically inspected baby formula plants at least once a year, but they did not inspect any of the three biggest manufacturers in 2020, according to federal records reviewed by The Associated Press.
When they finally did get inside an Abbott Nutrition formula plant in Michigan after a two-year gap, they found standing water and lax sanitation procedures. But inspectors offered only voluntary suggestions for fixing the problems and issued no formal warning.
