i believe that in the heat of the moment (the flood running rampant and everyone deciding to take the galactic kool aid) the forerunners may have forgotten about the few specimens they had stored away, or, more logically, had no means in which to dispose of them. since doing so would require to go deep into the halo installations, where the flood had been released and are coming from (giving that area the highest concentration of flood population.) im sure the idea crossed there minds but there wasnt anything they could do about it at that point.
