IN A PREVIOUS communication1 it was suggested that foods may play a role in the dissemination of the virus of poliomyelitis. Experimental evidence that flies may contaminate food was suggested by Ward, Melnick and Horstmann.2 Recent observations by Melnick and Penner3 have shown that a human strain of the virus of poliomyelitis may be recovered from excreta of fed flies for as long as three weeks.

In this work it was thought that means other than flies may possibly play a role in contaminating fresh foods with virus.

MATERIALS AND METHODS  Collections of stools were begun from 5 peddlers who delivered fresh fruits and vegetables from house to house in and around Salt Lake City. After the first two samples of stool were collected, 2 of these peddlers moved from the area. Three of the peddlers continued to work in the area chosen for the experimental work.
