Hi Kate,
From your photo, this looks more like a seed than anything left behind by an animal or insect. Is there something growing close to the lettuce that has gone to seed recently and could have dropped seed on your salad?
I'm afraid I cannot certify the safety of consuming something based on a photograph. The Clemson Cooperative Extension has prepared an information sheet on the safe handling of lettuce and you can read it at this link: https://hgic.clemson.edu/factsheet/safe-handling-of-lettuce-leafy-green-salads/. According to that article, grit or foreign objects that can be rinsed off are far less of a concern than bacteria which we cannot see.
You are fortunate that you have been able to keep your lettuce growing for such a long time - mine bolted long ago!
Best regards,
