	abstract = {A method, developed to detect low concentrations of virus on vegetables, irrigated with wastewater, was investigated in the field. Celery, spinach, lettuce and tomato crops, grown at an experimental station near Melbourne, Victoria, were spray-irrigated with stored wastewater, which had been seeded with either poliovirus or adenovirus. At specified intervals after irrigation, vegetables were harvested, washed to remove virus and the washings concentrated into a small volume which was inoculated into cell cultures for virus isolation. The method demonstrated rapid inactivation, within 48 h, of poliovirus on crops and low level persistence of this virus for up to 13 days. Adenovirus could not be detected on a lettuce crop as early as 24 h after irrigation. On crops harvested immediately after irrigation and stored at 4??C in a humid atmosphere in the dark, the method was able to demonstrate more gradual inactivation of poliovirus than under field conditions and virus persistence for up to 76 days. Since seeded virus concentrations were similar to those commonly detected in wastewater before storage, results indicate that this is a practical method for assessing viral contamination of vegetable crops spray-irrigated with wastewater. ?? 1987.},
