been initiated at Reed College, Portland, Oregon; University of
_ California at Berkeley and the University of Michigan at Ann Arbor.
The objective of these studies is to provide basie information cone
cerning the safety or non-safety of the eonsumption of highly irradiated
food products prior to the time that the technologic feasibility of
using fiseion products to sterilize foods is established.
