A nasal spray sold at CVS drug stores nationwide is being recalled. 

Bottles of CVS Health 12-Hour Sinus Relief Nasal Mist could be contaminated with a bacterium called pseudomonas aeruginosa. 

According to the Food and Drug Administration, using the nose spray could cause slight illness in most people. 

But for people with cystic fibrosis or immune disorders, the bacterium can be deadly. 

There have been no reports of illness associated with the nasal spray so far. 

Anybody who has purchased it should throw it away or return it to CVS.
