One potential effect (and probably the most important one) is that treated materials can offgas the toxic ethylene oxide for a variable period (depending on the nature of the plant material being treated).  Its effect as a potential human carcinogen probably rapidly decreases with time (especially given adequate air exchange), but its potential as a reproductive poison could be more troublesome to pregnant women in particular for a much longer period (even at lower concentrations).   I have no first hand knowledge, so would encourage you to read up on the hazard risks, including the following link:
