Not sure at what temp you pack jelly but if it's not above 180F then you will need to sterilize the jars, either by heating in the oven or immersing in boiling water for 2 min. I assume with jelly you're not going to want to invert them so you will probably need to sterilize the jars anyways so that the area above the jelly level is sterile. Ditto with the lids. Bacteria love sugar so if you leave any alive inside the sealed jars they will happily multiply! Of course if it's really good jelly it might get consumed long before that can happen!!
