PLoS ONE paper demonstrates "ubiquity" of DNA contamination

From The Scientist:

Fact or Artifact?  "A study documenting the ubiquity of DNA contamination calls into question a recent paper on food-derived nucleic acids in the human bloodstream. DNA from diverse species—including bacteria, plants, and humans—contaminates nearly every sample sent through a next-generation sequencer, according to a study published today (October 29) in PLOS ONE."

A dissertation from Kent State University (Attarhaie Tehrani 2011) in the OhioLINK Electronic Thesis and Dissertation Center discusses similar challenges for eliminating DNA contamination in research protocols.  Read the dissertation abstract in OhioLINK library catalog.
