Mark Pellin, Headline USA – It seems like only yesterday that President Joe Biden was heralding the delivery of scores of at-home COVID swab kits to help ease long lines at testing sites as the omicron variant swept through communities, leaving a trail of
high infection rates but relatively mild symptoms for most.

It turns out somebody should have done a better job testing the testing kits.Some of the kits that Biden had ordered delivered to about 50 million homes might contain a toxic substance that could be harmful to humans, according to USA Today.

"It is important to know that the extraction vial in many rapid antigen kits includes the chemical sodium azide as a preservative agent," informed Poison Control's National Capital Poison Center.

"The BinaxNow, BD Veritor, Flowflex, and Celltrion DiaTrust COVID-19 rapid antigen kits all contain this chemical," Poison Control's info-portal explained. "Sodium azide is a colorless, tasteless, and odorless powder that has been used as a propellant in automobile airbags, an herbicide, and a pest control agent."

And Uncle Joe potentially had it delivered to your doorstep.
