NASA announced decision to discontinue quarantine of astronauts, spacecraft, and lunar samples for remaining three Apollo flights. Dr. George M. Low, NASA Deputy Administrator, said NASA had concluded from analysis of Apollo 11, 12, and 14 quarantine information "that there is no hazard to man, animal, or plants in the lunar material. These results have been reviewed by the Interagency Committee on Back Contamination, and that committee has recommended that further lunar missions need not be subject to quarantine."
