I agree with NIMROD, one or two may not be an issue, but if the meat is infested with them then trash it and find another lake to fish. I've personally never seen a worm in a fish fillet, I have a buddy who caught some in Memphis in a small private lake and he showed a video of the worms in his fillets. It was literally dozens, I've heard urban ponds and small lakes are more prone to the spread. Yes cooking them at 325 degrees will kill them, but who wants to take a chance with parasites? I've seen brain worms in white-tailed, but never in the meat. Wouldn't chance anything if I wasn't 100% sure, besides you probably ain't going to enjoy eating the meat or fillet knowing what you dug out... just my two cents anyways..
