Peach Jam Odor?

I bought some peach jam from Safeway on Monday, and took it to work along with a loaf of bread from home. I was a little nonplussed at why the bread was already molding around the edges, but with a few swift cuts from my knife, those moldy sections were as good as gone. However, when I cracked open the new peach jam, I was nasally assaulted by its strong, pungent odor that can only be best described as sweaty feet that were bathed in a room of flatulence. However, the jam tastes great. I just have to plug my nose while eating it. In the tradition of SaveKaryn.com, I saved myself about $1.50 by not throwing out the moldy bread.
