The other night a reader found “a tiny white worm with what looked like a reddish brown head” in some precooked ham she bought. The reader bought and cooked (or technically recooked) the ham for dinner, and the following day she found the worm when eating leftovers. She looked through all the ham, but was only able to find one of the worms. The reader was wondering if we have any idea what the tiny white worms with the red or brown head might be.
