A top federal scientist sounded the alarm about what he feared was contamination in an Atlanta lab where the government made test kits for the coronavirus, according to sources familiar with the situation in Atlanta…

About a week ago, when the Secretary of Health and Human Services Alex Azar was under extreme pressure over the delays in getting coronavirus testing kits to market, Stenzel traveled to Atlanta to help troubleshoot whatever technical problems might have been occurring with the tests.

Stenzel was alarmed by the procedures he witnessed in the Atlanta laboratory and raised concerns with multiple CDC officials, per a source familiar with the situation in Atlanta.

Stenzel is a highly-regarded scientist and diagnostics expert. He was on the ground in Atlanta to deal with technical issues and happened to stumble upon the inappropriate procedures and possible contaminants. He is not a laboratory inspector and thus was not charged with producing an inspection report on the lab conditions.
