Pandemic Will Continue Limiting US FDA Inspections In Driving FY 2021 Drug GMP Warnings

FDA historically has based 100% of drug adulteration warning letters on inspections but COVID-19-related travel restrictions began changing that in FY 2020, when 2% of drug GMP warning letters were based on testing import samples. The change became even more pronounced in the first two months of FY 2021, with 59% of actions related to sample testing and 41% to inspections.
