poppy seeds have oil, and anything oily can go rancid.
in your fridge or freezer, they could be fine for years. however, stored in a warm place, for example near your stove, in a warm kitchen in the summer, etc., they could concievably go bad within a few months. the same with cookng oil, nuts, whole grain flours, etc.
rancid food has a distinctive acrid smell, and a bitter taste. i've read that they are carcinogenic. if you have any doubts, you should probably toss them out.
google and wikipedia should provide you with plenty of better detaled info.
