Preliminary tests show baking soda in daycare mailbox

HUNTSVILLE, AL (WAFF) -

Preliminary tests performed on a substance found in a Huntsville daycare's mailbox indicate the white, powdery substance is baking soda.

Police, fire, FBI, Drug Task Force and hazmat units were called to the scene of a daycare on Hammonds Avenue near Powers Avenue in North Huntsville Thursday afternoon.

Emergency responders on the scene said a white, powdery substance was found in a plastic bag in the daycare's mailbox. 

Officials said the children were removed from the daycare so emergency responders could investigate. "As long as it's unknown, it's dangerous until we can screen it," said Fire Chief Steve Britton. "We have a lot of high tech equipment on site to do preliminary tests."

Crews tested for drugs and other substances such as ricin and anthrax, but two tests later, results showed sodium bicarbonate, commonly known as baking soda.

Investigators said neither they nor the owners of the daycare know why or how a bag of baking soda wound up in their mailbox.
