Made ha mea bean soup and looks like maggots?

I just made ham and bean soup from the left over ham from Christmas. I had put the trimmings and bone into the freezer the night of Christmas dinner. I put the frozen bone and meat into the refrigerator 2 days ago to thaw it. I soaked the navy beans over night in a pan with a lid and boiled the bone and meat for about a 1/2 hour before straining the 'ham water' into another pot. I shredded the edible meat by hand and used the broth from the 'ham water' and started to boil/simmer that with the ham bone and beans. Anyway, its done now and seems to taste great. My question is...I see these little tiny things in the soup that look like cooked maggots. I took some out and they 'smear' between my fingers like a bean. What is it?? I didn't see any maggots when preparing and I would have no idea how they would have even gotten in it..but who knows?? Please let me know that what it could be. This is suppose to be dinner tonight with cornbread. And if they are maggots, obviously we are not eating it. OR..if it is something from the beans, that look like maggots..then I would feel better if someone could say so. Thanks for your help!
