worms in my food, can anyone ID?

I'd post a picture if I knew how.

I just made a pot of delicious pinto beans and ground beef (unfortunately, I did eat a tiny bit before realizing what I'd find in there). I'll give the ingredients at the end of this post. After the pot of food was cooked, I realized there were rice like worms in there. They looked like delicate pre-cooked basmati rice. Most were full bodied (not like small Tapeworm segments), maybe 3/4 cm in length or less, beige to white. My best guess is they came from the beans, as the meat was ground and looked very fresh, but I'd like to know for sure if they were from beans and not the meat, as other people got a taste as well and I am concerned. I did not notice any worms off the meat at any point, and if it did come from the meat, it'd either be a beef parasite and therefore ground up with the beef, or a fly landed on the meat before packing and hatched in a short time in refrigeration. The beans on the other hand had some shrivelled up skins on the top floating after soaking them which I did not discard. They were organic and I figured that'd add extra fibre. My theory is that they had worms on the insides (perhaps already dried up) that had eaten the insides of the beans and left the skins. Has anyone seen anything like this? (anyone know how I can post a picture? I will see if I can figure it out). If anyone can help, I'd greatly appreciate it! thanks ~ magma

Here's what was in the beans:
