Bacteria risks

US FDA recalls over 500,000 Covid tests over bacteria risk

The FDA said it "has significant concerns of bacterial contamination" in the test kit solution in some Pilot COVID-19 At-Home Tests.

Using the contaminated solution "may pose safety concerns" as well as cause the test to give an inaccurate result.

BBC reports the agency warned tests should be thrown out immediately.

Over 500,000 tests were distributed to the CVS drugstore and around 16,000 were distributed to Amazon.

None were made available through one of the federal government's testing programmes.
