CQ breaks a story today (available by subscription only) that I haven’t seen reported elsewhere yet (it’s not on the wires or reported by the St. Louis media):
An air monitoring system in St. Louis picked up particles of a biological agent on Monday that can be deadly in large doses.
Tularemia â€” also known as rabbit fever â€” is naturally found in the St. Louis region. But officials have been working since last night to determine whether the detection is a threat after a BioWatch sensor near Busch Stadium picked up the bacteria, according to a source familiar with the investigation.
Local officials have the lead on the investigation, but the Department of Homeland Security is closely monitoring the progress. Testing is on-going.
Update (10/17): The AP now has the story.
