FDA warns 4 hand sanitizer companies

April 21, 2011 12:00:00 AM PDT
The manufacturers of four hand sanitizers have been issued warnings by the federal government for making unsupported claims about their products.

The Food and Drug Administration sent warning letters to Tec Laboratories, JD Nelson, Dr. G.H. Tichener Antiseptic Co. and Oh So Clean Inc.

The FDA says these companies have been marketing sanitizers that claim to prevent a variety of infections like E. coli, and bird flu. Companies that claim their products can prevent a disease must submit a scientific study to the FDA before launching them.

The warning letter orders each manufacturer to correct the unsupported claims within 15 days.
