Fox News health columnist Colleen Cappon also cites a study from the University of North Carolina School of Dentistry which found that one out of five bib chains tested were contaminated with bacteria, including traces of Staphylococcus aureus and E. coli. The majority of bacteria growth was attributed to saliva, dental plaque, skin and flesh.

Cappon also references the work of Noel Kelsch, former president of the California Dental Hygienists' Association, whose own study was published in a recent issue of Infection Control Today.

"The more crevices and indentations on a clip or a chain, the higher the contaminant count," Kelsch tells Cappon.

Those contaminants, Cappon reports, can mean trouble for patients.
