What is the probability of the organism or a product of the organism causing 
harm? For this consideration, one should assume that establishment in the 
environment has occurred. The probability of harm can be estimated from an 
analysis of the known properties of the parental unmodified organism, and an 
informed judgement about the role the introduced material is likely to play 
in changing those properties. Results frcm laboratory and greenhouse tests 
will serve as the first tests of a prediction, but results from preliminary 
field tests will be the best test for unexpected consequences.
